Medical-care expenditures have been rising rapidly, accounting for almost one-fifth of GDP in 2009. In this study, we assess the sources of the rising medical-care expenditures in the commercial sector. We employ a novel framework for decomposing expenditure growth into four components at the disease level: service price growth, service utilization growth, treated disease prevalence growth, and demographic shift. The decomposition shows that growth in prices and treated prevalence are the primary drivers of medical-care expenditure growth over the 2003 to 2007 period. There was no growth in service utilization at the aggregate level over this period. Price and utilization growth were especially large for the treatment of malignant neoplasms. For many conditions, treated prevalence has shifted towards preventive treatment and away from treatment for late-stage illnesses.

A recent decline in geographic mobility in the United States may have been caused in part by falling house prices, through the “lock in” effects of financial constraints faced by households whose housing debt exceeds the market value of their home. I analyze the relationship between such “house lock” and the elevated levels and persistence of unemployment during the recent recession and its aftermath, using data that covers the period through the end of 2011. Because house lock will extend job search in the local labor market for homeowners whose home value has declined, I focus on differences in unemployment duration between homeowners and renters across geographic areas differentiated by the severity of the decline in home prices. The empirical analyses rely on microdata from the monthly Current Population Survey (CPS) files and an econometric method that enables the estimation of individual and aggregate covariate effects on completed unemployment durations in “synthetic cohort” (pseudo-panel) data. The estimates indicate the absence of a meaningful house lock effect on unemployment duration.

We discuss the magnitude of and reasons for the shift in the Beveridge curve in the U.S. since the Great Recession and argue that skill mismatch and the extension of unemployment insurance benefits likely have played a nontrivial role in this shift. We then introduce a method to estimate fitted Beveridge curves for other OECD countries for which data on vacancies and employment by job tenure are available. We show that Portugal, Spain, Sweden, and the U.K. also experienced rightward shifts in their Beveridge curves. We argue that the shift in the first three countries is due to similar mismatch factors as in the U.S. while the shift in Sweden is due to labor market reforms passed right before the Great Recession.

This paper develops a general-equilibrium model of skill-biased technological change that approximates the observed shifts in the shares of wage and non-wage income going to the top decile of U.S. households since 1980. Under realistic assumptions, we find that all agents can benefit from the technology change, provided that the observed rise in redistributive transfers over this period is taken into account. We show that the increase in capital’s share of total income and the presence of capital-entrepreneurial skill complementarity are two key features that help support the wages of ordinary workers as the new technology diffuses.

We simulate the Federal Reserve second Large-Scale Asset Purchase program in a DSGE model with bond market segmentation estimated on U.S. data. GDP growth increases by less than a third of a percentage point and inflation barely changes relative to the absence of intervention. The key reasons behind our findings are small estimates for both the elasticity of the risk premium to the quantity of long-term debt and the degree of financial market segmentation. Absent the commitment to keep the nominal interest rate at its lower bound for an extended period, the effects of asset purchase programs would be even smaller.

This paper presents the Economic Security Index (ESI), a new, more comprehensive measure of economic insecurity. By combining data from multiple surveys, we create an integrated measure of volatility in available household resources, accounting for fluctuations in income and out-of pocket medical expenses, as well as financial wealth sufficient to buffer against these shocks. We find that insecurity has risen steadily since the mid-1980s for virtually all subgroups of Americans, albeit with cyclical ups and downs. We also find, however, that there is substantial disparity in the degree to which different groups are exposed to economic risk. As the ESI derives from a data-independent conceptual foundation, it can be measured using different data sources. We find that the degree and disparity by which insecurity has risen is robust across these sources.

We explore the role of foreclosure inventories in a model of housing supply. The foreclosure variable is necessary to account for the steep and sustained drop in new construction activity following the U.S. housing market bust beginning in 2006. There is modest evidence that local banking conditions play a role in determining housing starts. Even with state-level foreclosures and banking variables in the model, there is a sizeable post-2006 residual common to all states. We argue that, in addition to observable macro and local factors, housing starts in the Great Recession have been weighed down in part by aggregate uncertainty factors

This paper describes a real-time, quarterly growth-accounting database for the U.S. business sector. The data on inputs, including capital, are used to produce a quarterly series on total factor productivity (TFP). In addition, the dataset implements an adjustment for variations in factor utilization—labor effort and the workweek of capital. The utilization adjustment follows Basu, Fernald, and Kimball (BFK, 2006). Using relative prices and input/output information, the series are also decomposed into separate TFP and utilization-adjusted TFP series for equipment investment (including consumer durables) and “consumption” (defined as business output less equipment and consumer durables).

This paper makes four points about the recent dynamics of productivity and potential output. First, after accelerating in the mid-1990s, labor and total-factor productivity growth slowed after the early to mid 2000s. This slowdown preceded the Great Recession. Second, in contrast to some informal commentary, productivity performance during the Great Recession and early in the subsequent recovery was roughly in line with previous experience during deep recessions. In particular, the evidence suggests substantial labor and capital hoarding. During the recovery, measures of factor utilization fairly quickly rebounded, and TFP and labor productivity returned to their anemic mid-2000s trends. Third, a plausible benchmark for the slower pace of underlying technology along with demographic assumptions from the Congressional Budget Office imply steady-state GDP growth of just over 2 percent per year—lower than most estimates. Finally, during the recession and recovery, potential output grew even more slowly— reflecting especially the effect of weak investment on growth in capital input. Half or more of the shortfall of actual output relative to pre-recession estimates of the potential trend reflects a reduction in potential.

A flexible labor margin allows households to absorb shocks to asset values with changes in hours worked as well as changes in consumption. This ability to absorb shocks along both margins greatly alters the household’s attitudes toward risk, as shown by Swanson (2012). The present paper extends that analysis to the case of generalized recursive preferences, as in Epstein and Zin (1989) and Weil (1989), including multiplier preferences, as in Hansen and Sargent (2001), all of which are used to bring macroeconomic models into closer agreement with asset pricing facts. Measures of risk aversion commonly used in the literature—including Cobb-Douglas composite good measures as well as traditional, fixed labor measures—show no stable relationship to the equity premium in a standard macroeconomic model, while the closed-form expressions derived in this paper match the equity premium closely. Thus, measuring risk aversion correctly is necessary for it to correspond to asset prices in the model.

We assess the importance of interpersonal income comparisons using data on suicide deaths. We examine whether suicide risk is related to others’ income, holding own income and other individual and environmental factors fixed. We estimate models of the suicide hazard using two independent data sets: (1) the National Longitudinal Mortality Study and (2) the National Center for Health Statistics’ Multiple Cause of Death Files combined with the 5 percent Public Use Micro Sample of the 1990 decennial census. Results from both data sources show that, controlling for own income and individual characteristics, individual suicide risk rises with others’ income.

Transportation spending often plays a prominent role in government efforts to stimulate the economy during downturns. Yet, despite the frequent use of transportation spending as a form of fiscal stimulus, there is little known about its short- or medium-run effectiveness. Does it translate quickly into higher employment and economic activity or does it impact the economy only slowly over time? This paper reviews the empirical findings in the literature for the United States and other developed economies and compares the effects of transportation spending to those of other types of government spending.

Long half-lives of real exchange rates are often used as evidence against monetary sticky price models. In this study we show how exchange rate regimes alter the long-run dynamics and half-life of the real exchange rate, and we recast the classic defense of such models by Mussa (1986) from an argument based on short-run volatility to one based on long-run dynamics. The first key result is that the extremely persistent real exchange rate found commonly in post Bretton Woods data does not apply to the preceding fixed exchange rate period in our sample, where the half-live was roughly half as large. This result suggests a reinterpretation of Mussa’s original finding, indicating that up to two thirds of the rise in variance of the real exchange rate in the recent floating rate period is actually due to the rise in persistence of the response to shocks, rather than due to a rise in the variance of shocks themselves. This result also suggests a way to resolve the “PPP puzzle,” reconciling real exchange rate persistence with volatility. The second key result explains the rise in persistence over time by identifying underlying shocks using a panel VECM model. Shocks to the nominal exchange rate induce more persistent real exchange rate responses compared to price shocks, and these shocks became more prevalent under a flexible exchange rate regime.

We examine optimal monetary policy under prevailing Chinese policy – including capital controls and nominal exchange rate targets – in a DSGE model calibrated to Chinese and global data. Under the closed capital account, domestic citizens are prohibited from holding foreign assets. Foreign currency revenues are sold to the central bank, which then sterilizes these purchases by issuing domestic debt. Uncovered interest parity conditions do not hold, so sterilization results in transfers between the private sector and the government. Given a negative shock to relative foreign interest rates, similar to that which occurred during the global financial crisis, sterilization costs increase and optimal policy calls for a reduction in sterilization activity, resulting in an easing of monetary policy and an increase in Chinese inflation. We then compare these dynamics to three alternative liberalizations: A partial opening of the capital account, removing the exchange rate peg, or doing both simultaneously. The regime with liberalized capital accounts and floating exchange rate yields the lowest losses to the central bank under the foreign interest rate shock. However, intermediate reforms do less well. In particular, letting the exchange rate float without opening the capital account results in higher losses following the interest rate shock than the benchmark case of no liberalization.

Previous research has established that the Federal Reserve large scale asset purchases (LSAPs) significantly influenced international bond yields. This paper analyzes the channels through which these effects occurred. We use dynamic term structure models to decompose international yield changes into changes in term premia and expected short rates. The conclusions for most countries are model dependent. Models that impose a unit root tend to imply large signaling effects for Australia, Canada, Germany and the United States. Models that do not restrict persistence imply negligible signaling effects for any country. Our preferred bias-corrected model implies large signaling effects for Canada and the United States. The idea that LSAP announcements signal information about Canadian rates is intuitively attractive because conventional US monetary policy shocks strongly predict Canadian rates.

Progress on the question of whether policymakers should respond directly to financial variables requires a realistic economic model that captures the links between asset prices, credit expansion, and real economic activity. Standard DSGE models with fully-rational expectations have difficulty producing large swings in house prices and household debt that resemble the patterns observed in many developed countries over the past decade. We introduce excess volatility into an otherwise standard DSGE model by allowing a fraction of households to depart from fully-rational expectations. Specifically, we show that the introduction of simple moving-average forecast rules for a subset of households can significantly magnify the volatility and persistence of house prices and household debt relative to otherwise similar model with fully-rational expectations. We evaluate various policy actions that might be used to dampen the resulting excess volatility, including a direct response to house price growth or credit growth in the central bank’s interest rate rule, the imposition of more restrictive loan-to-value ratios, and the use of a modified collateral constraint that takes into account the borrower’s loan-to-income ratio. Of these, we find that a loan-to-income constraint is the most effective tool for dampening overall excess volatility in the model economy. We find that while an interest-rate response to house price growth or credit growth can stabilize some economic variables, it can significantly magnify the volatility of others, particularly inflation.

We study the macroeconomic effects of uncertainty shocks in a DSGE model with labor search frictions and sticky prices. In contrast to a real business cycle model, the model with search frictions implies that uncertainty shocks reduce potential output, because a job match represents a long-term employment relation and heightened uncertainty reduces the value of a match. In the sticky-price equilibrium, an uncertainty shock--regardless of its source--consistently acts like an aggregate demand shock because it raises unemployment and lowers inflation. We present empirical evidence--based on a vector autoregression model and using a few alternative measures of uncertainty--that supports the theory's prediction that uncertainty shocks are aggregate demand shocks

I introduce a method that combines data from the U.S. Current Population Survey, Job Openings and Labor Turnover Survey, and state-level Job Vacancy Surveys to construct annual estimates of the number of job openings in the U.S. in the Spring by industry and occupation. I present these estimates for 2005-2011. The results reveal that: (i) During the Great Recession job openings for all occupations declined. (ii) Job openings rates and vacancy yields vary a lot across occupations. (iii) Changes in the occupation mix of job openings and hires account for the bulk of the decline in measured aggregate match efficiency since 2007. (iv) The majority of job openings in all industries and occupations are filled with persons who previously did not work in the same industry or occupation.

The standard argument for abstracting from capital accumulation in sticky-price macro models is based on their short-run focus: over this horizon, capital does not move much. This argument is more problematic in the context of real exchange rate (RER) dynamics, which are very persistent. In this paper we study RER dynamics in sticky-price models with capital accumulation. We analyze both a model with an economy-wide rental market for homogeneous capital, and an economy in which capital is sector specific. We find that, in response to monetary shocks, capital increases the persistence and reduces the volatility of RERs. Nevertheless, versions of the multi-sector sticky-price model of Carvalho and Nechio (2011) augmented with capital accumulation can match the persistence and volatility of RERs seen in the data, irrespective of the type of capital. When comparing the implications of capital specificity, we find that, perhaps surprisingly, switching from economy-wide capital markets to sector-specific capital tends to decrease the persistence of RERs in response to monetary shocks. Finally, we study how RER dynamics are affected by monetary policy and find that the source of interest rate persistence - policy inertia or persistent policy shocks - is key.

We use an arbitrage-free term structure model with spanned stochastic volatility to determine the value of the deflation protection option embedded in Treasury inflation-protected securities (TIPS). The model accurately prices the deflation protection option prior to the financial crisis when its value was near zero; at the peak of the crisis in late 2008 when deflationary concerns spiked sharply; and in the post-crisis period. During 2009, the average value of this option at the five-year maturity was 41 basis points on a par-yield basis.

We analyze the declines in government bond yields that followed the announcements of plans by the Federal Reserve and the Bank of England to buy longer-term government debt. Using empirical dynamic term structure models, we decompose these declines into changes in expectations about future monetary policy and changes in term premiums. We find that declines in U.S. Treasury yields mainly reflected lower policy expectations, while declines in U.K. yields appeared to reflect reduced term premiums. Thus, the relative importance of the signaling and portfolio balance channels of quantitative easing may depend on market institutional structures and central bank communications policies.

This paper investigates the problem of constructing prediction regions for forecast trajectories 1 to H periods into the future –a path forecast. We take the more general view that the null model is only approximative and in some cases it may be altogether unavailable. As a consequence, one cannot derive the usual analytic expressions nor resample from the null model as is usually done when bootstrap methods are used. The paper derives methods to construct approximate rectangular regions for simultaneous probability coverage which correct for serial correlation. The techniques appear to work well in simulations and in an application to the Greenbook path-forecasts of growth and inflation.

We examine the dynamic macroeconomic effects of public infrastructure investment both theoretically and empirically, using a novel data set we compiled on various highway spending measures. Relying on the institutional design of federal grant distributions among states, we construct a measure of government highway spending shocks that captures revisions in expectations about future government investment. We find that shocks to federal highway funding has a positive effect on local GDP both on impact and after 6 to 8 years, with the impact effect coming from shocks during (local) recessions. However, we find no permanent effect (as of 10 years after the shock). Similar impulse responses are found in a number of other macroeconomic variables. The transmission channel for these responses appears to be through initial funding leading to building, over several years, of public highway capital which then temporarily boosts private sector productivity and local demand. To help interpret these findings, we develop an open economy New Keynesian model with productive public capital in which regions are part of a monetary and fiscal union. We show that the presence of productive public capital in this model can yield impulse responses with the same qualitative pattern that we find empirically.

Using data on 24 teachers and 982 students from a 2006 survey of California high school economics classes, we assess the effects of student and teacher characteristics on student achievement. We estimate value-added models of outcomes on multiple choice and essay exams, with matched classroom pairs for each teacher enabling random-effects and fixed-effects estimation. Students’ own and peer GPAs and their attitudes towards economics have the largest effects on value-added scores. We also find a substantial impact of specialized teacher experience and college-level coursework in economics, although the latter is associated with higher scores on the multiple-choice test and lower scores on the essay test.

The zero lower bound on nominal interest rates has constrained the Federal Reserve's setting of the federal funds rate since December 2008. According to many macroeconomic models, this should have greatly reduced the effectiveness of monetary policy and increased the efficacy of fiscal policy. However, standard macroeconomic theory also implies that private-sector decisions depend on the entire path of expected future short-term interest rates, not just the current level of the federal funds rate. Thus, interest rates with a year or more to maturity are arguably more relevant for assessing the effects of the zero lower bound on the economy, and it is unclear to what extent the zero bound has constrained those yields. In this paper, we propose a novel approach to measure the effects of the zero lower bound on interest rates of any maturity. We compare the sensitivity of interest rates of various maturities to macroeconomic news during periods when short-term interest rates are very low to that during normal times. We find that yields on Treasury securities with six months or less to maturity were strongly affected by the zero bound during most or all of the period when the federal funds rate was near zero. In sharp contrast, yields with more than two years to maturity continued to respond to economic news in their usual way. One- and two-year Treasury yields represent an intermediate case, being only partially attenuated by the zero bound over part of the period when the funds rate was near zero. We discuss the implications of these findings for monetary and fiscal policy. Finally, we offer two explanations for our results: First, market participants often expected the zero bound to constrain policy for only a few quarters, minimizing its effects. Second, the Fed's unconventional policy actions may have helped offset the effects of the zero bound on medium- and longer-term rates.

We combine questions from the Michigan Survey about the future path of prices, interest rates, and unemployment to investigate whether U.S. households are aware of the so-called Taylor (1993) rule. For comparison, we perform the same analysis using questions from the Survey of Professional Forecasters. Our findings support the view that some households form their expectations about the future path of interest rates, inflation, and unemployment in a way that is consistent with Taylor-type rules. The extent to which this happens, however, does not appear to be uniform across income and education levels. In particular, we find evidence that the relationship between unemployment and interest rates is not properly understood by households in the lowest income quartile, and by those with no high school diploma. We also find evidence that the perceived effect of unemployment on interest rates is asymmetric, being relevant only for interest-rate decreases. Finally, we argue that the relationships we uncover can be given a causal interpretation.

We present evidence on the effects of large-scale asset purchases by the Federal Reserve and the Bank of England since 2008. We show that announcements about these purchases led to lower long-term interest rates and depreciations of the U.S. dollar and the British pound on announcement days, while commodity prices generally declined despite this more stimulative financial environment. We suggest that LSAP announcements likely involved signaling effects about future growth that led investors to downgrade their U.S. growth forecasts lowering longterm US yields, depreciating the value of the U.S. dollar, and triggering a decline in commodity prices. Moreover, our analysis illustrates the importance of controlling for market expectations when assessing these effects. We find that positive U.S. monetary surprises led to declines in commodity prices, even as long-term interest rates fell and the U.S. dollar depreciated. In contrast, on days of negative U.S. monetary surprises, i.e. when markets evidently believed that monetary policy was less stimulatory than expected, long-term yields, the value of the dollar, and commodity prices all tended to increase.

Since the end of the Great Recession in mid-2009, the unemployment rate has recovered slowly, falling by only one percentage point from its peak. We find that the lackluster labor market recovery can be traced in large part to weakness in aggregate demand; only a small part seems attributable to increases in labor market frictions. This continued labor market weakness has led to the highest level of long-term unemployment in the U.S. in the postwar period, and a blurring of the distinction between unemployment and nonparticipation. We show that flows from nonparticipation to unemployment are important for understanding the recent evolution of the duration distribution of unemployment. Simulations that account for these flows suggest that the U.S. labor market is unlikely to be subject to high levels of structural long-term unemployment after aggregate demand recovers.

This paper codifies in a systematic and transparent way a historical chronology of business cycle turning points for Spain reaching back to 1850 at annual frequency, and 1939 at monthly frequency. Such an exercise would be incomplete without assessing the new chronology itself and against others —this we do with modern statistical tools of signal detection theory. We also use these tools to determine which of several existing economic activity indexes provide a better signal on the underlying state of the economy. We conclude by evaluating candidate leading indicators and hence construct recession probability forecasts up to 12 months in the future.

This paper studies the role of credit in the business cycle, with a focus on private credit overhang. Based on a study of the universe of over 200 recession episodes in 14 advanced countries between 1870 and 2008, we document two key facts of the modern business cycle: financial-crisis recessions are more costly than normal recessions in terms of lost output; and for both types of recession, more credit-intensive expansions tend to be followed by deeper recessions and slower recoveries. In additional to unconditional analysis, we use local projection methods to condition on a broad set of macroeconomic controls and their lags. Then we study how past credit accumulation impacts the behavior of not only output but also other key macroeconomic variables such as investment, lending, interest rates, and inflation. The facts that we uncover lend support to the idea that financial factors play an important role in the modern business cycle.

We argue that positive co-movements between land prices and business investment are a driving force behind the broad impact of land-price dynamics on the macroeconomy. We develop an economic mechanism that captures the co-movements by incorporating two key features into a DSGE model: We introduce land as a collateral asset in firms’ credit constraints and we identify a shock that drives most of the observed fluctuations in land prices. Our estimates imply that these two features combine to generate an empirically important mechanism that amplifies and propagates macroeconomic fluctuations through the joint dynamics of land prices and business investment.

We study the interaction of borrower mortgage prepayment and mortgage delinquency during the period between 2001 and 2010. We show that when house prices flattened and began their subsequent decline, borrowers had increasingly slow prepayments and that this decline in prepayment rates roughly coincided with the sharp increase in their delinquency rates. Low credit score borrowers, in particular, display a pronounced negative correlation between default rates and prepayment rates. Shortfalls of actual prepayment rates from predicted rates based on an estimated prepayment model suggest that, in addition to the effects of declining house prices, tighter lending standards also may have played a role in weak prepayment activity.

We show that local house prices may be driven almost entirely by the demands of one identifiable group for several years and then by demands of another group at other times. We present evidence that house prices in Hawaii were subject to such regime shifts. Prices responded to demands associated with U.S. incomes and wealth for most years from 1975 through 2008. For about a decade starting in the middle of the 1980s, after the Japanese yen appreciated dramatically and Japanese housing and stock market wealth soared, however, house prices in Hawaii responded to Japanese incomes and wealth. Estimated models with these regime shifts outperformed conventional, constant coefficient models. The regime-shifting model helps explain why, when, and by how much the volatility and the elasticities of house prices in Hawaii with respect to the incomes and wealth of the U.S. and Japan varied over time

Using data from the Current Population Survey from 1980 through 2011 we examine what drives the variation and cyclicality of the growth rate of real wages over time. We employ a novel decomposition technique that allows us to divide the time series for median weekly earnings growth into the part associated with the wage growth of persons employed at the beginning and end of the period (the wage growth effect) and the part associated with changes in the composition of earners (the composition effect). The relative importance of these two effects varies widely over the business cycle. When the labor market is tight job switchers get large wage increases, making them account for half of the variation in median weekly earnings growth over our sample. Their wage growth, as well as that of job-stayers, is procyclical. During labor market downturns, this procyclicality is largely offset by the change in the composition of the workforce, leading aggregate real wages to be almost non-cyclical. Most of this composition effect works through the part-time employment margin. Remarkably, the unemployment margin neither accounts for much of the variation in nor much of the cyclicality of median weekly earnings growth.

A currency crisis is a speculative attack on the foreign exchange value of a currency, resulting in a sharp depreciation or forcing the authorities to sell foreign exchange reserves and raise domestic interest rates to defend the currency. This article discusses analytical models of the causes of currency and associated crises, presents basic measures of the incidence of crises, evaluates the accuracy of empirical models in predicting crises, and reviews work measuring the consequences of crises on the real economy. Currency crises have large measurable costs on the economy, but our ability to predict the timing and magnitude of crises is limited by our theoretical understanding of the complex interactions between macroeconomic fundamentals, investor expectations and government policy.

Previous research has emphasized the portfolio balance effects of Federal Reserve bond purchases, in which a reduced bond supply lowers term premia. In contrast, we find that such purchases have important signaling effects that lower expected future short-term interest rates. Our evidence comes from a model-free analysis and from dynamic term structure models that decompose declines in yields following Fed announcements into changes in risk premia and expected short rates. To overcome problems in measuring term premia, we consider bias-corrected model estimation and restricted risk price estimation. We also characterize the estimation uncertainty regarding the relative importance of the signaling and portfolio balance channels.

How do interest rates react to news? This paper presents a new methodology, based on a simple dynamic term structure model, which provides for an integrated analysis of the effects of monetary policy actions and macroeconomic news on the term structure of interest rates. I find several new empirical results: First, monetary policy directly affects distant forward rates. Second, policy news is more complex than macro news. Third, while payroll news causes the most action in interest rates, it does not affect distant forward rates. Fourth, the term structure response to macro news is consistent with considerable interest rate smoothing.

Analyzing university faculty and graduate student data for the top-ten U.S. economics departments between 1987 and 2007, we find that there are persistent differences in gender composition for both faculty and graduate students across institutions and that the share of female faculty and the share of women in the entering PhD class are positively correlated. We find, using instrumental variables analysis, robust evidence that this correlation is driven by the causal effect of the female faculty share on the gender composition of the entering PhD class. This result provides an explanation for persistent underrepresentation of women in economics, as well as for persistent segregation of women across academic fields.

While the global financial crisis was centered in the United States, it led to a surprising appreciation in the dollar, suggesting global dollar illiquidity. In response, the Federal Reserve partnered with other central banks to inject dollars into the international financial system. Empirical studies of the success of these efforts have yielded mixed results, in part because their timing is likely to be endogenous. In this paper, we examine the cross-sectional impact of these interventions. Theory consistent with dollar appreciation in the crisis suggests that their impact should be greater for countries that have greater exposure to the United States through trade and financial channels, less transparent holdings of dollar assets, and greater illiquidity difficulties. We examine these predictions for observed cross-sectional changes in CDS spreads, using a new proxy for innovations in perceived changes in sovereign risk based upon Google-search data. We find robust evidence that auctions of dollar assets by foreign central banks disproportionately benefited countries that were more exposed to the United States through either trade linkages or asset exposure. We obtain weaker results for differences in asset transparency or illiquidity. However, several of the important announcements concerning the international swap programs disproportionately benefited countries exhibiting greater asset opaqueness.

We provide cross-country evidence on the relative importance of cyclical and structural factors in explaining unemployment, including the sharp rise in U.S. long-term unemployment during the Great Recession of 2007-09. About 75% of the forecast error variance of unemployment is accounted for by cyclical factors--real GDP changes (Okun's law), monetary and fiscal policies, and the uncertainty effects emphasized by Bloom (2009). Structural factors, which we measure using the dispersion of industry-level stock returns, account for the remaining 25%. For U.S. long-term unemployment the split between cyclical and structural factors is closer to 60-40, including during the Great Recession.

Yes. We analyze the economic benefit of Treasury Inflation Protected Securities (TIPS) issuance by estimating the inflation risk premium that penalizes nominal Treasuries vis-a-vis TIPS and the cost derived from TIPS liquidity disadvantage. To account for the latter, we introduce a novel model-independent range for the liquidity premium in TIPS exploiting additional information from inflation swaps. We also adjust our model estimates for finite-sample bias. The resulting measure provides a lower bound to the benefit of TIPS, which is positive on average. Thus, our analysis suggests that the Treasury could save billions of dollars by significantly expanding its TIPS program.

How should monetary policy be conducted in the presence of endogenous feedback loops between asset prices, firms’ financial health, and economic activity? We reconsider this question in the context of the financial accelerator model and show that, when the level of natural output is inefficient, the optimal monetary policy under commitment leans considerably against movements in asset prices and risk premia. We demonstrate that an endogenous feedback loop is crucial for this result and that price stability is otherwise quasi-optimal absent this feature. We also show that the optimal policy can be closely approximated and implemented using a speed-limit rule that places a substantial weight on the growth of financial variables.

The importance of information asymmetries in the capital markets is commonly accepted as one of the main reasons for home bias in investment. We posit that effects of such asymmetries may be reduced through relationships between banks established through bank-to-bank lending and provide evidence to support this claim. To analyze dynamics of formation of such relationships during 1980-2009 time period, we construct a global banking network of 7938 banking institutions from 141 countries. We find that recessions and banking crises tend to have negative effects on the formation of new connections and that these effects are not the same for all countries or all banks. We also find that the global financial crisis of 2008-09 had a large negative impact on the formation of new relationships in the global banking network, especially by large banks that have been previously immune to effects of banking crises and recessions.

Data show that better creditor protection is correlated across countries with lower average stock market volatility. Moreover, countries with better creditor protection seem to have suffered lower decline in their stock market indexes during the current financial crisis. To explain this regularity, we use a Tobin q model of investment and show that stronger creditor protection increases the expected level and lowers the variance of stock prices in the presence of credit crunches. There are two main channels through which creditor protection enhances the performance of the stock market: (1) The credit-constrained stock price increases with better protection of creditors; (2) The probability of a credit crunch leading to a binding credit constraint falls with strong protection of creditors. We find strong empirical support for both predictions using data on stock market performance, amount and cost of credit, and creditor rights protection for 52 countries over the period 1980-2007. In particular, we find that crises are more frequent in countries with poor creditor protection. Using propensity score matching we also show that during crises stock market returns fall by more in countries with poor creditor protection.

The affine dynamic term structure model (DTSM) is the canonical empirical finance representation of the yield curve. However, the possibility that DTSM estimates may be distorted by small-sample bias has been largely ignored. We show that conventional estimates of DTSM coefficients are indeed severely biased, and this bias results in misleading estimates of expected future short-term interest rates and of long-maturity term premia. We provide a variety of bias-corrected estimates of affine DTSMs, both for maximally-flexible and over-identified specifications. Our estimates imply short rate expectations and term premia that are more plausible from a macro-finance perspective.

We document that trust in public institutions—and particularly trust in banks, business and government—has declined over recent years. U.S. time series evidence suggests that this partly reflects the pro-cyclical nature of trust in institutions. Cross-country comparisons reveal a clear legacy of the Great Recession, and those countries whose unemployment grew the most suffered the biggest loss in confidence in institutions, particularly in trust in government and the financial sector. Finally, analysis of several repeated cross-sections of confidence within U.S. states yields similar qualitative patterns, but much smaller magnitudes in response to state-specific shocks.

We construct probability forecasts for episodes of price deflation (i.e., a falling price level) using yields on nominal and real U.S. Treasury bonds. The deflation probability forecasts identify two "deflation scares" during the past decade: a mild one following the 2001 recession, and a more serious one starting in late 2008 with the deepening of the financial crisis. The estimated deflation probabilities are generally consistent with those from macroeconomic models and surveys of professional forecasters, but they also provide highfrequency insight into the views of financial market participants. The probabilities can also be used to price the deflation option embedded in real Treasury bonds.

A number of recent empirical studies have cast doubt on the "modernization theory" of democratization, which posits that increases in income are conducive to increases in democracy levels. This doubt stems mainly from the fact that while a strong positive correlation exists between income and democracy levels, the relationship disappears when one controls for country fixed effects. This raises the possibility that the correlation in the data reflects a third causal characteristic, such as institutional quality. In this paper, we reexamine the robustness of the income-democracy relationship. We extend the research on this topic in two imensions: first, we make use of newer income data, which allows for the construction of larger samples with more within-country observations. Second, we concentrate on panel estimation methods that explicitly allow for the fact that the primary measures of democracy are censored with substantial mass at the boundaries, or binary censored variables. Our results show that when one uses both the new income data available and a properly non linear estimator, a statistically significant positive income-democracy relationship is robust to the inclusion of country fixed effects.

This paper undertakes a modern event-study analysis of Operation Twist and compares its effects to those that should be expected for the recent quantitative policy announced by the Federal Reserve, dubbed "QE2". We first show that Operation Twist and QE2 are similar in magnitude. We identify six significant, discrete announcements in the course of Operation Twist that potentially could have had a major effect on financial markets, and show that four did have statistically significant effects. The cumulative effect of these six announcements on longer-term Treasury yields is highly statistically significant but moderate, amounting to about 15 basis points. This estimate is consistent both with Modigliani and Sutch’s (1966) time series analysis and with the lower end of empirical estimates of Treasury supply effects in the literature.

This paper investigates how concentrated ownership of capital influences the pricing of risky assets in a production economy. The model is designed to approximate the skewed distribution of wealth and income in U.S. data. I show that concentrated ownership significantly magnifies the equity risk premium relative to an otherwise similar representative-agent economy because the capital owner’s consumption is more strongly linked to volatile dividends from equity. A temporary shock to the technology for producing new capital (an “investment shock”) causes dividend growth to be much more volatile than aggregate consumption growth, as in long-run U.S. data. The investment shock can also be interpreted as a depreciation shock, or more generally, a financial friction that affects the supply of new capital. Under power utility with a risk aversion coefficient of 3.5, the model can roughly match the first and second moments of key asset pricing variables in long-run U.S. data, including the historical equity risk premium. About one-half of the model equity premium is attributable to the investment shock while the other half is attributable to a standard productivity shock. On the macro side, the model performs reasonably well in matching the business cycle moments of aggregate variables, including the pro-cyclical movement of capital’s share of total income in U.S. data.

The wage premium for high-skilled workers in the United States, measured as the ratio of the 90th-to-10th percentiles from the wage distribution, increased by 20 percent from the 1970s to the late 1980s. A large literature has emerged to explain this phenomenon. A leading explanation is that skill-biased technolog- ical change (SBTC) increased the demand for skilled labor relative to unskilled labor. In a calibrated vintage capital model with heterogenous labor, this paper examines whether SBTC is likely to have been a major factor in driving up the wage premium. Our results suggest that the contribution of SBTC is very small, accounting for about 1/20th of the observed increase. By contrast, a gradual and very modest shift in the distribution of human capital across workers can easily account for the large observed increase in wage inequality.

The U.S. unemployment rate has remained stubbornly high since the 2007-2009 recession leading many to conclude that structural, rather than cyclical, factors are to blame. Relying on a standard job search and matching framework and empirical evidence from a wide array of labor market indicators, we examine whether the natural rate of unemployment has increased since the recession began, and if so, whether the underlying causes are transitory or persistent. Our analyses suggest that the natural rate has risen over the past several years, with our preferred estimate implying an increase from its pre-recession level of close to a percentage point. An assessment of the underlying factors responsible for this increase, including labor market mismatch, extended unemployment benefits, and uncertainty about overall economic conditions, implies that only a small fraction of this increase is likely to be persistent.

Financial globalization opened international capital markets to investors and firms all over the world. Foreign capital raisings by firms have increased substantially since the early 1990s in terms of equity as well as debt. I review the literature on the determinants and patterns of cross-border capital raisings and their effects on developments of domestic markets, highlighting the differences between mature and emerging economies. I focus on the effects the introduction of the euro had on European and global capital markets by bringing into existence a currency area comparable in size to that of the United States. Finally, I discuss the effects of financial crises on foreign capital raisings and review capital raisings during the 2007-09 global financial crisis.

This paper performs Bayesian estimation of affine Gaussian dynamic term structure models (DTSMs) in which the risk price parameters are restricted. A new econometric framework for DTSM estimation allows the researcher to select plausible constraints from a large set of restrictions, to correctly quantify statistical uncertainty, and to incorporate model uncertainty. The main empirical result is that under the restrictions favored by the data the expectations component, and not the term premium, accounts for the majority of high-frequency movements of long-term interest rates. At lower frequencies, term premia are counter-cyclical and more stable than implied by DTSMs without risk price restrictions.

We update Rose and Spiegel (2010a, b) and search for simple quantitative models of macroeconomic and financial indicators of the "Great Recession" of 2008-09. We use a cross-country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars. We check a number of different indicators of crisis intensity, and a variety of different country samples. While countries with higher income and looser credit market regulation seemed to suffer worse crises, we find few clear reliable indicators in the pre-crisis data of the incidence of the Great Recession. Countries with current account surpluses seemed better insulated from slowdowns.

Before the recent recession, the consensus among researchers was that the zero lower bound (ZLB) probably would not pose a significant problem for monetary policy as long as a central bank aimed for an inflation rate of about 2 percent; some have even argued that an appreciably lower target inflation rate would pose no problems. This paper reexamines this consensus in the wake of the financial crisis, which has seen policy rates at their effective lower bound for more than two years in the United States and Japan and near zero in many other countries. We conduct our analysis using a set of structural and time series statistical models. We find that the decline in economic activity and interest rates in the United States has generally been well outside forecast confidence bands of many empirical macroeconomic models. In contrast, the decline in inflation has been less surprising. We identify a number of factors that help to account for the degree to which models were surprised by recent events. First, uncertainty about model parameters and latent variables, which were typically ignored in past research, significantly increases the probability of hitting the ZLB. Second, models that are based primarily on the Great Moderation period severely understate the incidence and severity of ZLB events. Third, the propagation mechanisms and shocks embedded in standard DSGE models appear to be insufficient to generate sustained periods of policy being stuck at the ZLB, such as we now observe. We conclude that past estimates of the incidence and effects of the ZLB were too low and suggest a need for a general reexamination of the empirical adequacy of standard models. In addition to this statistical analysis, we show that the ZLB probably had a first-order impact on macroeconomic outcomes in the United States. Finally, we analyze the use of asset purchases as an alternative monetary policy tool when short-term interest rates are constrained by the ZLB, and find that the Federal Reserve's asset purchases have been effective at mitigating the economic costs of the ZLB. In particular, model simulations indicate that the past and projected expansion of the Federal Reserve's securities holdings since late 2008 will lower the unemployment rate, relative to what it would have been absent the purchases, by 1-1/2 percentage points by 2012. In addition, we find that the asset purchases have probably prevented the U.S. economy from falling into deflation.

The negative relationship between the unemployment rate and the job openings rate, known as the Beveridge curve, has been relatively stable in the U.S. over the last decade. Since the summer of 2009, in spite of firms reporting more job openings, the U.S. unemployment rate has not declined in line with the Beveridge curve. We decompose the recent deviation from the Beveridge curve into different parts using data from the Job Openings and Labor Turnover Survey (JOLTS). We find that most of the current deviation from the Beveridge curve can be attributed to a shortfall in hires per vacancy. This shortfall is broad-based across all industries and is particularly pronounced in construction, transportation, trade, and utilities, and leisure and hospitality. Construction alone accounts for more than half of the Beveridge curve gap.

The passage of the 1996 welfare reform bill led to sweeping changes to the central U.S. cash safety net program for families with children. Importantly, along with other changes, the reform imposed lifetime time limits for receipt of welfare de facto ending the entitlement nature of cash welfare for poor families with children in the United States. Despite dire predictions about poverty and deprivation, the previous research shows that caseloads declined and employment increased, with no detectible increase in poverty or worsening of child-well-being. We re-evaluate these results in light of the severe recession which began in December 2007. In particular, we examine how the cyclicality of the response of program caseloads and family wellbeing has been altered by the implementation of welfare reform. We find that use of food stamps and non-cash safety net program participation have become significantly more responsive across economic cycles after welfare reform, going up more after reform when unemployment increases. By contrast, there is no evidence that cash welfare for families with children is more responsive after reform, and some evidence that it might be less so. There is some evidence that poverty increases more with the unemployment rate after reform (and no evidence that poverty increases less with unemployment after reform). We find that reform has led to no significant effects on the cyclical responsiveness of food consumption, food insecurity, health insurance, household crowding, or health.

Suicide is an important scientific phenomenon. Yet its causes remain poorly understood. This study documents a paradox: the happiest places have the highest suicide rates. The study combines findings from two large and rich individual‐level data sets—one on life satisfaction and another on suicide deaths—to establish the paradox in a consistent way across U.S. states. It replicates the finding in data on Western industrialized nations and checks that the paradox is not an artifact of population composition or confounding factors. The study concludes with the conjecture that people may find it particularly painful to be unhappy in a happy place, so that the decision to commit suicide is influenced by relative comparisons.

Engel (2005) derives a theoretical variance inequality involving the change in equilibrium stock prices Var (Δp) : Assuming that stock prices are "cum-dividend" and that investors are risk neutral, he shows that Var (Δp) must be greater than or equal to the variance of the "perfect foresight" (or "ex post rational") price change Var (Δp*) ; where p* is computed from the discounted stream of subsequent realized dividends. This paper expands the analysis to consider "ex-divdend" prices and risk aversion in a standard Lucas-type asset pricing model. I show that the direction of the price-change variance inequality can be reversed, depending on the values assigned to some key parameters of the model, namely the dividend AR(1) parameter, the investor's subjective time discount factor, and the coefficient of relative risk aversion. Overall, the results demonstrate that the present-value model of stock prices does not impose theoretical bounds on price-change volatility except in some special cases.

We explore the relationships between subjective well-being and income, as seen across individuals within a given country, between countries in a given year, and as a country grows through time. We show that richer individuals in a given country are more satisfied with their lives than are poorer individuals, and establish that this relationship is similar in most countries around the world. Turning to the relationship between countries, we show that average life satisfaction is higher in countries with greater GDP per capita. The magnitude of the satisfaction-income gradient is roughly the same whether we compare individuals or countries, suggesting that absolute income plays an important role in influencing well-being. Finally, studying changes in satisfaction over time, we find that as countries experience economic growth, their citizens‘ life satisfaction typically grows, and that those countries experiencing more rapid economic growth also tend to experience more rapid growth in life satisfaction. These results together suggest that measured subjective well-being grows hand in hand with material living standards.

Doubts about the accuracy with which outside investors can assess a banking firm’s value motivate many government interventions in the banking market. The recent financial crisis has reinforced concerns about the possibility that banks are unusually opaque. Yet the empirical evidence, thus far, is mixed. This paper examines the trading characteristics of bank shares over the period from January 1990 through September 2009. We find that bank share trading exhibits sharply different features before vs. during the crisis. Until mid‐2007, large (NYSE‐traded) banking firms appear to be no more opaque than a set of control firms, and smaller (NASD‐traded) banks are, at most, slightly more opaque. During the crisis, however, both large and small banking firms exhibit a sharp increase in opacity, consistent with the policy interventions implemented at the time. Although portfolio composition is significantly related to market microstructure variables, no specific asset category(s) stand out as particularly important in determining bank opacity.

Foreign stock ownership is known to be very limited among households. Using the Survey of Consumer Finances, I show that information acquisition plays a major role in agents’ decisions to invest in foreign stocks. In particular, households that participate in foreign stock markets are better informed about their financial investment choices: they shop more for investment opportunities, update their investment portfolios more frequently, and use the Internet more often as a source of information. Households that invest in foreign stocks are also substantially wealthier and more educated. The paper considers a model that shows how information acquisition costs and fixed costs of entering a new market can affect investors’ decisions to buy foreign stocks. The model predictions match the two main features of the data: that foreign stock owners are scarce but better informed. Calibrating the model to match returns and volatility for the U.S. and foreign stocks, I show that even a small cost of entering a new market can explain the large degree of nonparticipation among households.

This paper studies the effects of Job Creation Tax Credits (JCTCs) enacted by U.S. states over the past 20 years. First, we investigate whether JCTCs stimulate within-state job growth. Second, we evaluate when JCTCs' effects occur? In particular, we test for negative anticipation effects between JCTC enactment and when legislation goes into effect. Third, we assess from where any increased employment comes from – in-state or out-of-state? These questions are investigated in an event study framework applied to monthly panel data on employment, the JCTC effective and legislative dates, and various controls.

This paper employs a standard asset pricing model with power-utility to derive theoretical volatility measures for the price-dividend ratio and the real equity return in a setting that allows for varying degrees of investor information about future dividends. For reasonable levels of risk aversion, we show that the model can match the observed volatility in long-run U.S. data if investors can accurately foresee future dividends. The variance of the model price-dividend ratio increases monotonically with investor information about future dividends whereas the relationship between equity return variance and information is non-monotonic. Finally, we derive a theoretical variance decomposition for the fundamental price-dividend ratio and show that it differs in important ways from the data. Specifically, even though the model can account for observed stock market volatility, it does so by generating an implausibly volatile risk-free rate combined with an insufficiently predictable excess return on equity.

The degree of exchange-rate pass-through to import prices is low. An average passthrough estimate for the 1980s would be roughly 50 percent for the United States implying that, following a 10 percent depreciation of the dollar, a foreign exporter selling to the U.S. market would raise its price in the United States by 5 percent. Moreover, substantial evidence indicates that the degree of pass-through has since declined to about 30 percent. Gust, Leduc, and Vigfusson (2010) demonstrate that, in the presence of pricing complementarity, trade integration spurred by lower costs for importers can account for a significant portion of the decline in pass-through. In our framework, pass-through declines solely because of markup adjustments along the intensive margin. In this paper, we model how the entry and exit decisions of exporting firms affect pass-through. This is particularly important since the decline in pass-through has occurred as a greater concentration of foreign firms are exporting to the United States. We find that the effect of entry on pass-through is quantitatively small and is more than offset by the adjustment of markups that arise only along the intensive margin. Even though entry has a relatively small impact on pass-through, it nevertheless plays an important role in accounting for the secular rise in imports relative to GDP. In particular, our model suggests that over 3/4 of the rise in the U.S. import share since the early 1980s is due to trade in new goods. Thus, a key insight of this paper is that adjustment of markups that occur along the intensive margin are quantitatively more important in accounting for secular changes in pass-through than adjustments that occur along the extensive margin.

We argue that credit constraints not just amplify fundamental shocks, they can also lead to self-fulfilling business cycles. To make this point, we study a model in which productive firms are credit constrained, with credit limits determined by equity value. A drop in equity value tightens credit constraints and reallocates resources from productive to unproductive firms. This reallocation reduces aggregate productivity and further depresses equity value and further tightens credit constraints, generating a financial multiplier that amplifies the effects of fundamental shocks. At the aggregate level, credit externality manifests as increasing returns and thus can lead to self-fulfilling business cycles.

In this paper we demonstrate that private firms in China have more difficult access to external finance than state owned firms and argue that they make adjustments to reduce their demand for external funds. In particular, we show that private firms have lower levels of inventory and trade credit and that these levels decrease with the difficulty of obtaining external finance. Nevertheless, we find no evidence that these lower levels of inventory and trade credit lead to lower productivity or profitability.

This paper presents a model comparing the optimal degree of asset class diversification abroad by a central bank and a sovereign wealth fund. We show that if the central bank manages its foreign asset holdings in order to meet balance of payments needs, particularly in reducing the probability of sudden stops in foreign capital inflows, it will place a high weight on holding safer foreign assets. In contrast, if the sovereign wealth fund, acting on behalf of the Treasury, maximizes the expected utility of a representative domestic agent, it will opt for relatively greater holding of more risky foreign assets. We also show how the diversification differences between the strategies of the bank and SWF is affected by the government's delegation of responsibilities and by various parameters of the economy, such as the volatility of equity returns and the total amount of public foreign assets available for management.

The paper models monetary policy in China using a hybrid McCallum-Taylor empirical reaction function. The feedback rule allows for reactions to inflation and output gaps, and to developments in a trade-weighted exchange rate gap measure. The investigation finds that monetary policy in China has, on average, accommodated inflationary developments. But exchange rate shocks do not significantly affect monetary policy behavior, and there is no evidence of a structural break in the estimated reaction function at the end of the strict dollar peg in July 2005. The paper also runs an exercise incorporating survey-based inflation expectations into the policy reaction function and meets with some success.

We derive aggregate growth-accounting implications for a two-sector economy with heterogeneous capital subsidies and monopoly power. In this economy, measures of total factor productivity (TFP) growth in terms of quantities (the primal) and real factor prices (the dual) can diverge from each other as well as from true technology growth. These distortions potentially give rise to dynamic reallocation effects that imply that change in technology needs to be measured from the bottom up rather than the top down. We show an example, for Singapore, of how incomplete data can be used to obtain estimates of aggregate and sectoral technology growth as well as reallocation e¤ects. We also apply our framework to reconcile divergent TFP estimates in Singapore and to resolve other empirical puzzles regarding Asian development.

This paper estimates the “jobs multiplier” of fiscal stimulus spending using the state-level allocations of federal stimulus funds from the American Recovery and Reinvestment Act (ARRA) of 2009. Because the level and timing of stimulus funds that a state receives was potentially endogenous, I exploit the fact that most of these funds were allocated according to exogenous formulary allocation factors such as the number of federal highway miles in a state or its youth share of population. Cross-state IV results indicate that ARRA spending in its first year yielded about eight jobs per million dollars spent, or $125,000 per job.

In the aftermath of WorldWar II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies. This acceleration is correlated with the incidence of U.S. economic aid and technical assistance in the same period. We interpret this as supportive of the interpretation that technology transfers from the U.S. to Western European countries and Japan were an important factor in driving growth in these recipient countries during the postwar decades.

We investigate the effectiveness of capital controls in insulating economies from currency crises, focusing in particular on both direct and indirect effects of capital controls and how these relationships may have changed over time in response to global financial liberalization and the greater mobility of international capital. We predict the likelihood of currency crises using standard macroeconomic variables and a probit equation estimation methodology with random effects. We employ a comprehensive panel data set comprised of 69 emerging market and developing economies over 1975-2004. Both standard and duration-adjusted measures of capital control intensity (allowing controls to "depreciate" over time) suggest that capital controls have not effectively insulated economies from currency crises at any time during our sample period. Maintaining real GDP growth and limiting real overvaluation are critical factors preventing currency crises, not capital controls. However, the presence of capital controls greatly increases the sensitivity of currency crises to changes in real GDP growth and real exchange rate overvaluation, making countries more vulnerable to changes in fundamentals. Our model suggests that emerging markets weathered the 2007-08 crisis relatively well because of strong output growth and exchange rate flexibility that limited overvaluation of their currencies.

The persistence of aggregate real exchange rates is a prominent puzzle, particularly since adjustment of international relative prices in microeconomic data is much faster. This paper finds that adjustment to the law of one price in disaggregated data is not just a faster version of the adjustment to purchasing power parity in the aggregate data; while aggregate real exchange rate adjustment works primarily through the foreign exchange market, adjustment in disaggregated data is a qualitatively distinct process, working through adjustment in local-currency goods prices. These distinct adjustment dynamics appear to arise from distinct classes of shocks generating macro and micro price deviations. A vector error correction model nesting aggregate and disaggregated relative prices permits identification of distinct macroeconomic and good-specific shocks. When half-lives are estimated conditional on shocks, the macro-micro disconnect puzzle disappears: microeconomic relative prices adjust to macro shocks just as slowly as do aggregate real exchange rates. These results provide evidence against theories of real exchange rate behavior based on sticky prices and on heterogeneity across goods.

This chapter studies optimal monetary stabilization policy in interdependent open economies, by proposing a unified analytical framework systematizing the existing literature. In the model, the combination of complete exchange-rate pass-through ("producer currency pricing") and frictionless asset markets ensuring efficient risk sharing results in a form of open-economy "divine coincidence": in line with the prescriptions in the baseline New Keynesian setting, the optimal monetary policy under cooperation is characterized by exclusively inward-looking targeting rules in domestic output gaps and GDP-deflator inflation. The chapter then examines deviations from this benchmark, when cross-country strategic policy interactions, incomplete exchange-rate pass-through ("local currency pricing") and asset market imperfections are accounted for. Namely, failure to internalize international monetary spillovers results in attempts to manipulate international relative prices to raise national welfare, causing inefficient real exchange rate fluctuations. Local currency pricing and incomplete asset markets (preventing efficient risk sharing) shift the focus of monetary stabilization to redressing domestic as well as external distortions: the targeting rules characterizing the optimal policy are not only in domestic output gaps and inflation, but also in misalignments in the terms of trade and real exchange rates, and cross-country demand imbalances.

What monetary policy framework, if adopted by the Federal Reserve, would have avoided the Great Inflation of the 1960s and 1970s? We use counterfactual simulations of an estimated model of the U.S. economy to evaluate alternative monetary policy strategies. We show that policies constructed using modern optimal control techniques aimed at stabilizing inflation, economic activity, and interest rates would have succeeded in achieving a high degree of economic stability as well as price stability only if the Federal Reserve had possessed excellent information regarding the structure of the economy or if it had acted as if it placed relatively low weight on stabilizing the real economy. Neither condition held true. We document that policymakers at the time both had an overly optimistic view of the natural rate of unemployment and put a high priority on achieving full employment. We show that in the presence of realistic informational imperfections and with an emphasis on stabilizing economic activity, an optimal control approach would have failed to keep inflation expectations well anchored, resulting in high and highly volatile inflation during the 1970s. Finally, we show that a strategy of following a robust first-difference policy rule would have been highly effective at stabilizing inflation and unemployment in the presence of informational imperfections. This robust monetary policy rule yields simulated outcomes that are close to those seen during the period of the Great Moderation starting in the mid-1980s.

This paper estimates the amount of tightening in bank commercial and industrial (C&I) loan rates during the financial crisis. After controlling for loan characteristics and bank fixed effects, as of 2010:Q1, the average C&I loan spread was 66 basis points or 23 percent above normal. From about 2005 to 2008, the loan spread averaged 23 basis points below normal. Thus, from the unusually loose lending conditions in 2007 to the much tighter conditions in 2010:Q1, the average loan spread increased by about 1 percentage point. I find that large and medium-sized banks tightened their loan rates more than small banks; while small banks tended to tighten less, they always charged more. Using loan size to proxy for bank-dependent borrowers, while small loans tend to have a higher spread than large loans, I find that small loans actually tightened less than large loans in both absolute and percentage terms. Hence, the results do not indicate that bank-dependent borrowers suffered more from bank tightening than large borrowers. The channels through which banks tightened loan rates include reducing the discounts on large loans and raising the risk premium on more risky loans. There also is evidence that noncommitment loans were priced significantly higher than commitment loans at the height of the liquidity shortfall in late 2007 and early 2008, but this premium dropped to zero following the introduction of emergency liquidity facilities by the Federal Reserve. In a cross section of banks, certain bank characteristics are found to have significant effects on loan prices, including loan portfolio quality, capital ratios, and the amount of unused loan commitments. These findings provide evidence on the supply-side effect of loan pricing.

This paper focuses on simple normative rules for monetary policy which central banks can use to guide their interest rate decisions. Such rules were first derived from research on empirical monetary models with rational expectations and sticky prices built in the 1970s and 1980s. During the past two decades substantial progress has been made in establishing that such rules are robust. They perform well with a variety of newer and more rigorous models and policy evaluation methods. Simple rules are also frequently more robust than fully optimal rules. Important progress has also been made in understanding how to adjust simple rules to deal with measurement error and expectations. Moreover, historical experience has shown that simple rules can work well in the real world in that macroeconomic performance has been better when central bank decisions were described by such rules. The recent financial crisis has not changed these conclusions, but it has stimulated important research on how policy rules should deal with asset bubbles and the zero bound on interest rates. Going forward the crisis has drawn attention to the importance of research on international monetary issues and on the implications of discretionary deviations from policy rules.

Using survey-based measures of future U.S. economic activity from the Livingston Survey and the Survey of Professional Forecasters, we study how changes in expectations, and their interaction with monetary policy, contribute to fluctuations in macroeconomic aggregates. We find that changes in expected future economic activity are a quantitatively important driver of economic fluctuations: a perception that good times are ahead typically leads to a significant rise in current measures of economic activity and inflation. We also find that the short-term interest rate rises in response to expectations of good times as monetary policy tightens. Our results provide quantitative evidence on the importance of expectations-driven business cycles and on the role that monetary policy plays in shaping them.

Over the years, U.S. banks have increasingly relied on the bond market to finance their business. This created the potential for a link between the bond market and the corporate sector whereby borrowers, including those that do not rely on bond funding, became exposed to the conditions in the bond market. We investigate the importance of this link. Our results show that when the cost to access the bond market goes up, banks that rely on bond financing charge higher interest rates on their loans. Banks that rely exclusively on deposit funding follow bond financing banks and increase the interest rates on their loans, though by smaller amounts. Further, banks pass the bond market shocks predominantly to their risky borrowers that have access to the bond market and to their borrowers that do not have access to the bond market. These results show that banks propagate shocks to the bond market by passing them through their loan policies to their borrowers, including those that do not use bond financing.

This paper documents the adjustment of the labor market during the recession, and places it in the broader context of previous postwar downturns. What emerges is a picture of labor market dynamics with three key recurring themes: 1. From the perspective of a wide range of labor market outcomes, the 2007 recession represents the deepest downturn in the labor market in the postwar era. 2. Until recently, the nature of labor market adjustment in the current recession has displayed a notable resemblance to that observed in past severe downturns. 3. During the latter half of 2009, however, the path of adjustment has exhibited important departures from that seen in prior deep recessions.

We study the purchasing power parity (PPP) puzzle in a multi-sector, two-country, sticky-price model. Across sectors, firms differ in the extent of price stickiness, in accordance with recent microeconomic evidence on price setting in various countries. Combined with local currency pricing, this leads sectoral real exchange rates to have heterogeneous dynamics. We show analytically that in this economy, deviations of the real exchange rate from PPP are more volatile and persistent than in a counterfactual one-sector world economy that features the same average frequency of price changes, and is otherwise identical to the multi-sector world economy. When simulated with a sectoral distribution of price stickiness that matches the microeconomic evidence for the U.S. economy, the model produces a half-life of deviations from PPP of 39 months. In contrast, the half-life of such deviations in the counterfactual one-sector economy is only slightly above one year. As a by-product, our model provides a decomposition of this difference in persistence that allows a structural interpretation of the different approaches found in the empirical literature on aggregation and the real exchange rate. In particular, we reconcile the apparently conflicting findings that gave rise to the "PPP Strikes Back debate" (Imbs et al. 2005a,b and Chen and Engel 2005).

Housing is an important component of the consumption basket. Since both rental prices and goods prices are sticky, the literature suggests that optimal monetary policy should stabilize both types of prices, with the optimal weight on rental inflation proportional to the housing expenditure share. In a two-sector DSGE model with sticky rental prices and goods prices, however, we find that the optimal weight on rental inflation in the Taylor rule is small--much smaller than that implied by the housing expenditure share. We show that the asymmetry in policy responses to rent inflation versus goods inflation stems from the asymmetry in factor intensity between the two sectors.

We examine the determinants of issuance of yen-denominated international bonds over the period from 1990 through 2010. This period was marked by low Japanese interest rates that led some investors to pursue \carry trades," which consisted of funding investments in higher interest rate currencies with low interest rate, yen-denominated obligations. In principle, bond issuers that have exibility in their funding currency could also conduct a carry-trade strategy by funding in yen during this low interest rate period. We examine the characteristics of firms who appeared to have adopted this strategy using a data set containing almost 80,000 international bond issues. Our results suggest that there was a movement towards issuing in yen in the international bond markets starting in 2003, but this appears to have ended with the outbreak of the global financial crisis in 2007. Furthermore, the breakdown of carry-trade conditions in 2007 corresponds to a resurgence in the ability of economic fundamentals, such as the volume of trade with Japan, to explain the decision to issue international bonds denominated in yen.

We discover and document errors in public use microdata samples ("PUMS files") of the 2000 Census, the 2003-2006 American Community Survey, and the 2004-2009 Current Population Survey. For women and men ages 65 and older, age- and sex-specific population estimates generated from the PUMS files differ by as much as 15% from counts in published data tables. Moreover, an analysis of labor force participation and marriage rates suggests the PUMS samples are not representative of the population at individual ages for those ages 65 and over. PUMS files substantially underestimate labor force participation of those near retirement ages and overestimate labor force participation rates of those at older ages. These problems were an unintentional by-product of the misapplication of a newer generation of disclosure avoidance procedures carried out on the data. The resulting errors in the public use data could significantly impact studies of people ages 65 and older, particularly analyses of variables that are expected to change by age.

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple equilibria it is first necessary to understand how an economy arrives to a particular equilibrium. In this paper, we employ notions of learnability, self-enforceability, and properness to motivate and develop a suite of equilibrium selection criteria. Central among these criteria are whether the equilibrium is learnable by private agents and jointly learnable by private agents and the policymaker. We use two New Keynesian policy models to identify the strategic interactions that give rise to multiple equilibria and to illustrate our equilibrium selection methods. Importantly, unless the Pareto-preferred equilibrium is learnable by private agents, we find little reason to expect coordination on that equilibrium.

During the past decade, much new research has combined elements of finance, monetary economics, and macroeconomics in order to study the relationship between the term structure of interest rates and the economy. In this survey, I describe three different strands of such interdisciplinary macro-finance term structure research. The first adds macroeconomic variables and structure to a canonical arbitrage-free finance representation of the yield curve. The second examines bond pricing and bond risk premiums in a canonical macroeconomic dynamic stochastic general equilibrium model. The third developsa new class of arbitrage-free term structure models that are empirically tractable and well suited to macro-finance investigations.

The standard model of strategic tax competition – the non-cooperative tax-setting behavior of jurisdictions competing for a mobile capital tax base – assumes that government policymakers are perfectly benevolent, acting solely to maximize the utility of the representative resident in their jurisdiction. We depart from this assumption by allowing for the possibility that policymakers also may be influenced by the rent-seeking (lobbying) behavior of businesses. Businesses recognize the factors affecting policymakers’ welfare and may make campaign contributions to influence tax policy. This extension to the standard strategic tax competition model implies that business contributions may affect not only the levels of equilibrium tax rates but also the slope of the tax reaction function between jurisdictions. Thus, business campaign contributions may directly influence business tax rates, as well as indirectly shape tax competition, and enhance or retard the mobility of capital across jurisdictions. Based on a panel of 48 U.S. states and unique data on business campaign contributions, our empirical work uncovers four key results. First, we document a significant direct effect of business contributions on tax policy. Second, the economic value of a $1 business campaign contribution in terms of lower state corporate taxes is approximately $6.65. Third, the slope of the reaction function between tax policy in a given state and the tax policies of its competitive states is negative, and this slope is robust to business campaign contributions. Fourth, we document the sensitivity of the empirical results to state effects.

Previous studies on financial frictions have been unable to establish the empirical significance of credit constraints in macroeconomic fluctuations. This paper argues that the muted impact of credit constraints stems from the absence of a mechanism to explain the observed persistent comovements between housing prices and business investment. We develop such a mechanism by incorporating two key features into a DSGE model: we identify shocks that shift the demand for collateral assets and we allow productive agents to be credit-constrained. A combination of these two features enables our model to successfully generate an empirically important mechanism that amplifies and propagates macroeconomic fluctuations through credit constraints.

We join the new trade theory with a model of choice between bank and bond financing to show the differential effects of financial policy on the distribution of firm size, welfare, aggregate output, gains from trade, and the real exchange rate in a small open economy. Increasing bank efficiency and reducing bond transaction costs both increase welfare but have opposite effects on the extensive margin of trade, aggregate exports, and the real exchange rate. Increasing the degree of trade openness increases firms. relative demand for bond versus bank financing. We identify a financial switching channel for gains from trade where increasing access to export markets allows firms to overcome high fixed costs of bond issuance to secure a lower marginal cost of capital.

In dynamic stochastic general equilibrium (DSGE) models, the household’s labor margin as well as consumption margin affects Arrow-Pratt risk aversion. This paper derives simple, closed-form expressions for risk aversion that take into account the household’s labor margin. Ignoring the labor margin can lead to wildly inaccurate measures of the household’s true attitudes toward risk. We show that risk premia on assets computed using the stochastic discount factor are proportional to Arrow-Pratt risk aversion, so that measuring risk aversion correctly is crucial for understanding asset prices. Closed-form expressions for risk aversion in DSGE models with generalized recursive preferences and internal and external habits are also derived.

We draw on stylized facts from the finance literature to build a model where altering the relative costs of bank and bond financing changes the entire distribution of firm size, with implications for the aggregate capital stock, output, and welfare. Reducing transactions costs in the bond market increases the output and profits of mid-sized firms at the expense of both the largest and smallest firms. In contrast, reducing the frictions involved in bank lending promotes the expansion of the smallest firms while all other firms shrink, even as it increases the profitability of both small and mid-size firms. Although both policies increase aggregate output and welfare, they have opposite effects on the extensive margin of production--promoting bond issuance causes exit while cheaper bank credit induces entry. When reducing transactions costs in one market, the resulting increase in output and welfare are largest when transactions costs in the other market are very high.

We examine how the economy responds to both disembodied and embodied technology shocks in a model with vintage capital. We focus on what happens when there is a change in the number of vintages of capital that are in use at any one time and on what happens when there is a change in the persistence of the shocks hitting the economy. The data suggest that these kinds of changes took place in the U.S. economy in the 1990s, when the pace of embodied technical progress appears to have accelerated. We find that embodied technology shocks lead to greater variability (of output, investment and labor allocations) than disembodied shocks of the same size. On the other hand, a decrease in the number of vintages in use at any time (such as is likely to occur when the pace of technical progress accelerates) tends to reduce the volatility of output and also to differentiate the initial response of the economy to the two shocks.

This paper reexamines the implications of the zero lower bound on interest rates for monetary policy and the optimal choice of steady-state inflation in light of the experience of the recent global recession. There are two main findings. First, the zero lower bound did not materially contribute to the sharp declines in output in the United States and many other economies through the end of 2008, but it is a significant factor slowing recovery. Model simulations imply that an additional 4 percentage points of rate cuts would have kept the unemployment rate from rising as much as it has and would bring the unemployment and inflation rates more quickly to steady-state values, but the zero bound precludes these actions. This inability to lower interest rates comes at the cost of $1.7 trillion of foregone output over four years. Second, if recent events are a harbinger of a significantly more adverse macroeconomic climate than experienced over the preceding two decades, then a 2 percent steady-state inflation rate may provide an inadequate buffer to keep the zero bound from having noticeable deleterious effects on the macroeconomy assuming the central bank follows the standard Taylor Rule. In such an adverse environment, stronger systematic countercyclical fiscal policy and/or alternative monetary policy strategies can mitigate the harmful effects of the zero bound with a 2 percent inflation target. However, even with such policies, an inflation target of 1 percent or lower could entail significant costs in terms of macroeconomic volatility.

We compare the ex ante observable risk characteristics, the default performance, and the pricing of securitized mortgage loans and mortgage loans retained by the original lender. We find that privately securitized fixed and adjustable-rate mortgages are riskier ex ante than lender-retained loans or loans securitized through the government sponsored agencies. We do not find any evidence of differential loan performance for privately securitized fixed-rate mortgages. However, we do find evidence that privately securitized adjustable-rate mortgages performed worse than retained mortgages, even after controlling for a large number of risk factors. Despite the higher measures of ex ante risk, the loan rates on privately securitized adjustable-rate mortgages were lower than for retained mortgages.

This document describes the construction of and data sources for a state-level panel data set measuring output and factor use for the manufacturing sector. These data are a subset of a larger, comprehensive data set that we currently are constructing and hope to post on the FRBSF website in the near future. The comprehensive data set will cover the U.S. manufacturing sector and may be thought of as a state-level analog to other widely used productivity data sets such as the industry-level NBER Productivity Database or Dale Jorgenson's "KLEM" database or the country-level Penn World Tables, but with an added emphasis on adjusting prices for taxes. The selected variables currently available for public use are nominal and real gross output, nominal and real investment, and real capital stock. The data cover all fifty states and the period 1963 to 2006.

We study optimal exercise by mortgage borrowers of the option to default. Also, we use an equilibrium valuation model incorporating default to show how mortgage yields and lender recovery rates on defaulted mortgages depend on initial loan-to-value ratios when borrowers default optimally. The analysis treats both the frictionless case and the case in which borrowers and/or lenders incur deadweight costs upon default. The model is calibrated using data on California mortgages. We find that the model's principal testable implication for default and mortgage pricing--that default rates and yield spreads will be higher for high loan-to-value mortgages--is borne out empirically.

We present new measures of household-specific inflation experiences based on comprehensive information from the Consumer Expenditure Survey (CEX). We match households in the Interview and the Diary Surveys from the CEX to produce both complete and detailed pictures of household expenditures. The resulting household inflation measures are based on a more accurate and detailed description of household expenditures than those previously available. We find that our household-based inflation measures track aggregate measures such as the CPI-U quite well and that the addition of Diary Survey data induces small but significant differences in the measurement of household inflation. The distribution of inflation experiences across households exhibits a large amount of dispersion over the entire sample period. In addition, we uncover a significantly negative relationship between mean inflation and inflation inequality across households.

This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model. Our analysis is conducted on a cross-section of 85 countries; we focus on international linkages that may have allowed the crisis to spread across countries. Our model of the cross-country incidence of the crisis combines 2008 changes in real GDP, the stock market, country credit ratings, and the exchange rate. We explore the linkages between these manifestations of the crisis and a number of its possible causes from 2006 and earlier. The causes we consider are both national (such as equity market run-ups that preceded the crisis) and, critically, international financial and real linkages between countries and the epicenter of the crisis. We consider the United States to be the most natural origin of the 2008 crisis, though we also consider six alternative sources of the crisis. A country holding American securities that deteriorate in value is exposed to an American crisis through a financial channel. Similarly, a country which exports to the United States is exposed to an American downturn through a real channel. Despite the fact that we use a wide number of possible causes in a flexible statistical framework, we are unable to find strong evidence that international linkages can be clearly associated with the incidence of the crisis. In particular, countries heavily exposed to either American assets or trade seem to behave little differently than other countries; if anything, countries seem to have benefited slightly from American exposure.

This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model. Our analysis is conducted on a cross-section of 107 countries; we focus on national causes and consequences of the crisis, ignoring crosscountry “contagion” effects. Our model of the incidence of the crisis combines 2008 changes in real GDP, the stock market, country credit ratings, and the exchange rate. We explore the linkages between these manifestations of the crisis and a number of its possible causes from 2006 and earlier. We include over sixty potential causes of the crisis, covering such categories as: financial system policies and conditions; asset price appreciation in real estate and equity markets; international imbalances and foreign reserve adequacy; macroeconomic policies; and institutional and geographic features. Despite the fact that we use a wide number of possible causes in a flexible statistical framework, we are unable to link most of the commonly-cited causes of the crisis to its incidence across countries. This negative finding in the cross-section makes us skeptical of the accuracy of “early warning” systems of potential crises, which must also predict their timing.

How should monetary authorities react to an oil price shock? The New Keynesian literature has concluded that ensuring complete price stability is the optimal thing to do. In contrast, this paper argues that a meaningful trade-off between stabilizing inflation and the welfare relevant output gap arises in a distorted economy once one recognizes (i) that oil (energy) cannot be easily substituted by other factors in the short-run, (ii) that there is no fiscal transfer available to policymakers to neutralize the steady-state distortion due to monopolistic competition, and (iii) that increases in oil prices also directly affect consumption by raising the price of fuel, heating oil, and other energy sources. While the first two conditions are necessary to introduce a microfounded monetary policy trade-off, the third one makes it quantitatively significant. The optimal precommitment monetary policy relies on unobservables and is therefore hard to implement. To address this concern, I derive a simple interest rate feedback rule that mimics the optimal plan in all relevant dimensions but that depends only on observables, namely core inflation, oil price inflation, and the growth rate of output.

In this paper, we derive a linear-quadratic model for monetary policy analysis that is consistent with sticky prices and search and matching frictions in the labor market. We show that the second-order approximation to the welfare of the representative agent depends on inflation and "gaps" that involve current and lagged unemployment. Our approximation makes explicit how the costs of fluctuations are generated by the presence of search frictions. These costs are distinct from the costs associated with relative price dispersion and fluctuations in consumption that appear in standard new Keynesian models. We use the model to analyze optimal monetary policy under commitment and discretion and to show that the structural characteristics of the labor market have important implications for optimal policy.

We examine the impact of foreign underwriting activity on bond markets using issuelevel data in the Japanese "Samurai" and euro-yen bond markets. Firms choosing Japanese underwriters tend to be Japanese, riskier, and smaller. We find that Japanese underwriting fees, while higher overall on average, are actually lower after conditioning for issuer characteristics. Moreover, firms tend to sort properly in their choice of underwriter, in the sense that a switch in underwriter nationality would be predicted to result in an increase in underwriting fees. Finally, we conduct a matching exercise to examine the 1995 liberalization of foreign access to the "Samurai" bond market, using yen-denominated issues in the euro-yen market as a control. Foreign entry led to a statistically and economically significant decrease in underwriting fees in the Samurai bond market, as spreads fell by an average of 23 basis points. Overall, our results suggest that the market for underwriting services is partially segmented by nationality, as issuers appear to have preferred habitats, but entry increases market competition.

In response to the global financial crisis that started in August 2007, central banks provided extraordinary amounts of liquidity to the financial system. To investigate the effect of central bank liquidity facilities on term interbank lending rates, we estimate a six-factor arbitrage-free model of U.S. Treasury yields, financial corporate bond yields, and term interbank rates. This model can account for fluctuations in the term structure of credit risk and liquidity risk. A significant shift in model estimates after the announcement of the liquidity facilities suggests that these central bank actions did help lower the liquidity premium in term interbank rates.

We explore the distortions in business cycle models arising from inefficiencies in price setting and in the search process matching firms to unemployed workers, and the implications of these distortions for monetary policy. To this end, we characterize the tax instruments that would implement the first best equilibrium allocations and then examine the trade-offs faced by monetary policy when these tax instruments are unavailable. Our findings are that the welfare cost of search inefficiency can be large, but the incentive for policy to deviate from the inefficient flexible-price allocation is in general small. Sizable welfare gains are available if the steady state of the economy is inefficient, and these gains do not depend on the existence of an inefficient dispersion of wages. Finally, the gains from deviating from price stability are larger in economies with more volatile labor flows, as in the U.S.

By many objective measures the lives of women in the United States have improved over the past 35 years, yet we show that measures of subjective well-being indicate that women’s happiness has declined both absolutely and relative to men. The paradox of women’s declining relative well-being is found across various datasets, measures of subjective well-being, and is pervasive across demographic groups and industrialized countries. Relative declines in female happiness have eroded a gender gap in happiness in which women in the 1970s typically reported higher subjective well-being than did men. These declines have continued and a new gender gap is emerging—one with higher subjective well-being for men.

This paper uses data from surveys of expected inflation to learn how expectations processes have changed following recent changes in the behavior of inflation. Households do not appear to have recognized the change in the process, and are placing substantially more weight than appears warranted on recent inflation data when forming expectations about inflation over the next year. At first glance, professional forecasters do appear to have changed how they predict inflation. But a closer look at the data reveals that professionals are relying on core rather than headline inflation, and are placing too much weight on recent core inflation data. These errors show up in a noticeable (absolute and relative) deterioration in the forecast accuracy of both households and professionals.

Identifying productivity and real demand shocks in the US with sign restrictions based on standard theory, we provide evidence on real and financial channels of their international propagation. Productivity gains in US manufacturing have substantial macroeconomic effects, raising US consumption, investment and the terms of trade, relative to the rest of the world, while lowering US net exports. Significant international …nancial adjustment occurs via a rise in the global value of the US stock market, portfolio shifts in US foreign assets and liabilities, and especially real dollar appreciation. Positive demand shocks to US manufacturing also lead to real appreciation and raise investment, but have otherwise limited effects on trade flows. This evidence suggests a fundamental role of cross-country endogenous demand and wealth movements in shaping international macroeconomic interdependence.

We examine the effects of the most durable employer health insurance mandate in the United States, Hawaii’s Prepaid Health Care Act, using Current Population Survey data covering the years 1979 to 2005. We find that Hawaii’s law increased insurance coverage over time for worker groups with low rates of coverage in the voluntary market. We find no statistically significant support for the hypothesis that the mandate reduced wages and employment probabilities. Instead, its primary detectable effect was an increased reliance on part-time workers who are exempt from the law. We arrive at these conclusions in part by use of a variation of the classical Fisher permutation test that compares the magnitude of the estimated “Hawaii effect” to “placebo effects” estimated for the other US states.

Regional inequality in China appears to be persistent and even growing in the past two decades. We study potential offsetting factors and interprovincial migration to shed light on the sources of this persistence. We find that some of the inequality could be attributed to differences in quality of labor, industry composition, and geographical location of provinces. We also demonstrate that interprovincial migration, while driven in part by wage differences across provinces, does not offset these differences. Finally, we find that interprovincial redistribution did not help offset regional inequality during our sample period.

Economists are skeptical about the economic benefits of hosting "mega-events" such as the Olympic Games or the World Cup, since such activities have considerable cost and seem to yield few tangible benefits. These doubts are rarely shared by policymakers and the population, who are typically quite enthusiastic about such spectacles. In this paper, we reconcile these positions by examining the economic impact of hosting mega-events like the Olympics; we focus on trade. Using a variety of trade models, we show that hosting a mega-event like the Olympics has a positive impact on national exports. This effect is statistically robust, permanent, and large; trade is around 30% higher for countries that have hosted the Olympics. Interestingly however, we also find that unsuccessful bids to host the Olympics have a similar positive impact on exports. We conclude that the Olympic effect on trade is attributable to the signal a country sends when bidding to host the games, rather than the act of actually holding a mega-event. We develop a political economy model that formalizes this idea, and derives the conditions under which a signal like this is used by countries wishing to liberalize.

Potential output is an important concept in economics. Policymakers often use a one-sector neoclassical model to think about long-run growth, and often assume that potential output is a smooth series in the short run--approximated by a medium- or long-run estimate. But in both the short and long run, the one-sector model falls short empirically, reflecting the importance of rapid technical change in producing investment goods; and few, if any, modern macroeconomic models would imply that, at business cycle frequencies, potential output is a smooth series. Discussing these points allows us to discuss a range of other issues that are less well understood, and where further research could be valuable.

We provide a set of comparable estimates for the rates of inflow to and outflow from unemployment using publicly available data for fourteen OECD economies. We then devise a method to decompose changes in unemployment into contributions accounted for by changes in inflow and outflow rates for cases where unemployment deviates from its flow steady state, as it does in many countries. Our decomposition reveals that fluctuations in both inflow and outflow rates contribute substantially to unemployment variation within countries. For Anglo-Saxon economies we find approximately a 15:85 inflow/outflow split to unemployment variation, while for Continental European and Nordic countries, we observe much closer to a 45:55 split. Using the estimated flow rates we compute gross worker flows into and out of unemployment. In all economies we observe that increases in inflows lead increases in unemployment, whereas outflows lag a ramp up in unemployment.

We construct a price index with weights on the prices of different PCE goods chosen to minimize the welfare costs of nominal distortions: a cost-of-nominal-distortions index (CONDI). We compute these weights in a multisector New Keynesian model with time-dependent price setting, calibrated using U.S. data on the dispersion of price stickiness and labor shares across sectors. We find that the CONDI weights mostly depend on price stickiness and are less affected by the dispersion in labor shares. Moreover, CONDI stabilization leads to negligible welfare losses compared to the optimal policy and is better approximated by core rather than headline inflation targeting. An even better approximation of the CONDI can be obtained with an adjusted core index that covers total expenditures excluding autos, clothing, energy, and food at home, but that includes food away from home.

Managing the credit risk inherent to a corporate credit line is similar to that of a term loan, but with one key difference. For both instruments, the bank should know the borrower's probability of default (PD) and the facility's loss given default (LGD). However, since a credit line allows the borrowers to draw down the committed funds according to their own needs, the bank must also have a measure of the line's exposure at default (EAD). Our study, which is based on a census of all corporate lending within Spain over the last 20 years, provides the most comprehensive overview of corporate credit line use and EAD calculations to date. Our analysis shows that defaulting firms have significantly higher credit line usage rates and EAD values up to five years prior to their actual default. Furthermore, we find that there are important variations in EAD values due to credit line size, collateralization, and maturity. While our results are derived from data for a single country, they should provide useful benchmarks for further academic, business and policy research into this underdeveloped area of credit risk management.

We examine the sources of macroeconomic economic fluctuations by estimating a variety of medium-scale DSGE models within a unified framework that incorporates regime switching both in shock variances and in the inflation target. Our general framework includes a number of different model features studied in the literature. We propose an efficient methodology for estimating regime-switching DSGE models. The model that best fits the U.S. time-series data is the one with synchronized shifts in shock variances across two regimes and the fit does not rely on strong nominal rigidities. We find little evidence of changes in the inflation target. We identify three types of shocks that account for most of macroeconomic fluctuations: shocks to total factor productivity, wage markup, and the capital depreciation rate.

Consumption-habits have become an integral component in new Keynesian models. However, consumption-habits can be modeled in a host of different ways and this diversity is reflected in the literature. I examine whether different approaches to modeling consumption habits have important implications for business cycle behavior. Using a standard new Keynesian business cycle model, I show that, to a first-order log-approximation, the consumption Euler equation associated with the additive functional form for habit formation encompasses the multiplicative function form. Empirically, I show that whether consumption habits are internal or external has little effect on the model's business cycle characteristics.

Differences between yields on comparable-maturity U.S. Treasury nominal and real debt, the so-called breakeven inflation (BEI) rates, are widely used indicators of inflation expectations. However, better measures of inflation expectations could be obtained by subtracting inflation risk premiums from the BEI rates. We provide such decompositions using an estimated affine arbitrage-free model of the term structure that captures the pricing of both nominal and real Treasury securities. Our empirical results suggest that long-term inflation expectations have been well anchored over the past few years, and inflation risk premiums, although volatile, have been close to zero on average.

This paper presents statistical analysis supporting stylized facts about sovereign wealth funds (SWFs). It discusses the forces leading to the growth of SWFs, including the role of fuel exports and ongoing current account surpluses, and large hoarding of international reserves. It analyzes the degree to which measures of SWF governance and transparency compare with national norms of behavior. We provide evidence that many countries with SWFs are characterized by effective governance but weak democratic institutions, as compared to other nonindustrial countries. We also present a model with which we compare the optimal degree of diversification abroad by a central bank versus that of a sovereign wealth fund. We show that if the central bank manages its foreign assets with the objective of reducing the probability of sudden stops, it will place a high weight on the downside risk of holding risky assets abroad and will tend to hold primarily safe foreign assets. In contrast, if the sovereign wealth fund, acting on behalf of the Treasury, maximizes the expected utility of a representative domestic agent, it will opt for relatively greater holding of more risky foreign assets. We discuss how the degree of a country's transparency may affect the size of the foreign asset base entrusted to a wealth fund's management, and show that, for relatively low levels of public foreign assets, assigning portfolio management independence to the central bank may be advantageous. However, for a large enough foreign asset base, the opportunity cost associated with the limited portfolio diversification of the central bank induces authorities to establish a wealth fund in pursuit of higher returns.

In recent years China has faced an increasing trilemma--how to pursue an independent domestic monetary policy and limit exchange rate flexibility, while at the same time facing large and growing international capital flows. This paper analyzes the impact of the trilemma on China's monetary policy as the country liberalizes its goods and financial markets and integrates with the world economy. It shows how China has sought to insulate its reserve money from the effects of balance of payments inflows by sterilizing through the issuance of central bank liabilities. However, we report empirical results indicating that sterilization dropped precipitously in 2006 in the face of the ongoing massive buildup of international reserves, leading to a surge in reserve money growth. We estimate a vector error correction model linking the surge in China's reserve money to broad money, real GDP, and the price level. We use this model to explore the inflationary implications of different policy scenarios. Under a scenario of continued rapid reserve money growth (consistent with limited sterilization of foreign exchange reserve accumulation) and strong economic growth, the model predicts a rapid increase in inflation. A model simulation using an extension of the framework that incorporates recent increases in bank reserve requirements also implies a rapid rise in inflation. By contrast, model simulations incorporating a sharp slowdown in economic growth lead to less inflation pressure even with a substantial buildup in international reserves.

The term premium on nominal long-term bonds in the standard dynamic stochastic general equilibrium (DSGE) model used in macroeconomics is far too small and stable relative to empirical measures obtained from the data--an example of the "bond premium puzzle." However, in models of endowment economies, researchers have been able to generate reasonable term premiums by assuming that investors have recursive Epstein-Zin preferences and face long-run economic risks. We show that introducing Epstein-Zin preferences into a canonical DSGE model can also produce a large and variable term premium without compromising the model's ability to fi…t key macroeconomic variables. Long-run real and nominal risks further improve the model's ability to …fit the data with a lower level of household risk aversion.

Nominal rigidities are generally viewed as important for the transmission of monetary policy. We argue that nominal rigidities are important also for the transmission of technology shocks, especially for explaining their effects on hours and real wages. Evidence suggests that a positive technology shock leads to a short-run decline in labor hours and a gradual rise in real wages. We examine the ability of an RBC model augmented with real frictions, a pure sticky-price model, a pure sticky-wage model, and a model combining sticky prices and sticky wages in accounting for this evidence. We find that, according to this metric, the model with nominal wage and price rigidities is more successful than others. This finding is robust and holds true for a relatively small Frisch elasticity of hours and a relatively high frequency of price reoptimization that are consistent with microeconomic evidence.

Between 1992 and 2002, the Japanese Import Price Index (IPI) registered a decline of almost 9 percent and Japan entered a period of deflation. We show that much of the correlation between import prices and domestic prices was due to formula biases. Had the IPI been computed using a pure Laspeyres index like the CPI, the IPI would have hardly moved at all. A Laspeyres version of the IPI would have risen 1 percentage point per year faster than the official index. Second we show that Chinese prices did not behave differently from the prices of other importers. Although Chinese prices are substantially lower than the prices of other exporters, they do not exhibit a differential trend. However, we estimate that the typical price per unit quality of a Chinese exporter fell by half between 1992 and 2005. Thus the explosive growth in Chinese exports is attributable to growth in the quality of Chinese exports and the increase in new products being exported by China.

This paper provides a detailed overview of China's participation in international trade using newly available data on the universe of globally engaged Chinese firms over the 2003-2005 period. We document the distribution of trade flows and product- and trade-partner intensity across both exporting and importing firms and study the relationship between firms' intensive and extensive margins of trade. We also compare trade patterns across firms of different organizational structure, distinguishing between domestic private firms, domestic state‐owned firms, foreign-owned firms, and joint ventures. We explore the variation in foreign ownership across sectors, and find results consistent with recent theoretical and empirical work on the role of credit constraints and contractual imperfections in international trade and investment. Finally, we examine the rapid expansion of China's trade over the 2003-2005 period, and decompose it into its extensive and intensive margins. We also use monthly data and study the frequent churning and reallocation of trade flows across firms and across products and trade partners within firms.

Why are foreigners willing to invest almost $2 trillion per year in the United States? The answer affects if the existing pattern of global imbalances can persist and if the United States can continue to finance its current account deficit without a major change in asset prices and returns. This paper tests various hypotheses and finds that standard portfolio allocation models and diversification motives are poor predictors of foreign holdings of U.S. liabilities. Instead, foreigners hold greater shares of their investment portfolios in the United States if they have less-developed financial markets. The magnitude of this effect decreases with income per capita. Countries with fewer capital controls and greater trade with the United States also invest more in U.S. equity and bond markets, and there is no evidence that foreigners invest in the United States based on diversification motives. The empirical results showing a primary role of financial market development in driving foreign purchases of U.S. portfolio liabilities supports recent theoretical work on global imbalances.

We explore the implications of current account adjustment for monetary policy within a simple two country SGE model. Our framework nests Obstfeld and Rogoff's (2005) static model of exchange rate responsiveness to current account reversals. It extends this approach by endogenizing the dynamic adjustment path and by incorporating production and nominal price rigidities in order to study the role of monetary policy. We consider two different adjustment scenarios. The first is a "slow burn" where the adjustment of the current account deficit of the home country is smooth and slow. The second is a "fast burn" where, owing to a sudden shift in expectations of relative growth rates, there is a rapid reversal of the home country's current account. We examine several different monetary policy regimes under each of these scenarios. Our principal finding is that the behavior of the domestic variables (for instance, output, inflation) is quite sensitive to the monetary regime, while the behavior of the international variables (for instance, the current account and the real exchange rate) is less so. Among different policy rules, domestic inflation targeting achieves the best stabilization outcome of aggregate variables. This result is robust to the presence of imperfect pass-through on import prices, although in this case stabilization of consumer price inflation performs similarly well.

Recent models of international equity portfolios exhibit two potential weaknesses: (1) the structure of equilibrium equity portfolios is determined by the correlation of equity returns with real exchange rates, yet empirically equities don't appear to be a good hedge against real exchange rate risk; (2) Equity portfolios are highly sensitive to preference parameters. This paper solves both problems. It first shows that, in more general and realistic environments, the hedging of real exchange rate risks occurs through international bond holdings since relative bond returns are strongly correlated with real exchange rate fluctuations. Equilibrium equity positions are then optimally determined by the correlation of equity returns with the return on nonfinancial wealth, conditional on the bond returns. The model delivers equilibrium portfolios that are well-behaved as a function of the underlying preference parameters. We find reasonable empirical support for the theory for G-7 countries. We are able to explain short positions in domestic currency bonds for all G-7 countries, as well as significant levels of home equity bias for the U.S., Japan, and Canada.

Fixed transaction costs and delivery lags are important costs of international trade. These costs lead firms to import infrequently and hold substantially larger inventories of imported goods than domestic goods. Using multiple sources of data, we document these facts. We then show that a parsimoniously parameterized model economy with importers facing an (S, s)-type inventory management problem successfully accounts for these features of the data. Moreover, the model can account for import and import price dynamics in the aftermath of large devaluations. In particular, desired inventory adjustment in response to a sudden, large increase in the relative price of imported goods creates a short-term trade implosion, an immediate, temporary drop in the value and number of distinct varieties imported, as well as a slow increase in the retail price of imported goods. Our study of six current account reversals following large devaluation episodes in the last decade provide strong support for the model's predictions.

South Korea's growth miracle has been well documented. A large set of institutional and policy reforms in the early 1960s is thought to have contributed to the country's extraordinary performance. In this paper, we assess the importance of one key set of policies, the trade policy reforms in Korea, as well as the concurrent GATT tariff reductions. We develop a model of neoclassical growth and trade that highlights two forces by which lower trade barriers can lead to increased per worker GDP: comparative advantage and specialization, and capital accumulation. We calibrate the model and simulate the effects of three sets of tariff reductions that occurred between the early 1962 and 1995. Our main finding is that the model can explain up to 32 percent of South Korea's catch-up to the G7 countries in output per worker in the manufacturing sector. We find that the effects of the tariff reductions taken together are about twice as large as the sum of each reduction applied individually.

This paper addresses two substantive issues: (1) Does the magnitude of the expectation effect of regime switching in monetary policy depend on a particular policy regime? (2) Under which regime is the expectation effect quantitatively important? Using two canonical DSGE models, we show that there exists asymmetry in the expectation effect across regimes. The expectation effect under the dovish policy regime is quantitatively more important than that under the hawkish regime. These results suggest that the possibility of regime shifts in monetary policy can have important effects on rational agents' expectation formation and on equilibrium dynamics. They offer a theoretical explanation for the empirical possibility that a policy shift from the dovish regime to the hawkish regime may not be the main source of substantial reductions in the volatilities of inflation and output.

The monetary policy literature assumes increasingly that policies are formulated according to the timeless perspective (Woodford, 1999a). However, treating the auxiliary state variables that characterize the timeless perspective equilibrium appropriately when evaluating policy performance, this paper shows that discretionary policymaking can be superior to timeless perspective policymaking and identifies model features that make this outcome more likely. Using standard New Keynesian DSGE models, discretion is found to dominate timeless perspective policymaking when the price/wage Phillips curves are relatively flat, due, perhaps, to firm-specific capital (or labor) and/or Kimball (1995) aggregation in combination with nominal rigidities. These results suggest that studies applying the timeless perspective might also usefully compare its performance to discretion, paying careful attention to how policy performance is evaluated.

We make use of micro-level data for over 45,000 private bond issues by over 5000 firms from 22 countries in 1990-2006 to analyze the impact that the launch of the EMU had on their currency denomination. The use of the micro data allows us to isolate the "euro effect" on new and seasoned bond issuers while conditioning on individual issue characteristics. To our knowledge, ours is the first systematic analysis of this topic at the micro level. We find that the impact on new issuers is larger than on seasoned issuers and that most of the increase in the euro-denominated bond issuance by seasoned borrowers was along the "extensive" margin, i.e. borrowers switching currency denomination of their issues. Insofar as new entrants to the bond market will define the overall currency composition in the long run, these results imply that aggregate studies might be underestimating the euro effect. We also find that to a large extent the increase in euro issuance was "at the expense" of U.S. dollar issuance, suggesting that euro competes with the U.S. dollar as a currency of choice for international financial transactions.

The use of subjective well-being (SWB) data for investigating the nature of individual preferences has increased tremendously in recent years. There has been much debate about the cross-sectional and time series patterns found in these data, particularly with respect to the relationship between SWB and relative status. Part of this debate concerns how well SWB data measures true utility or preferences. In a recent paper, Daly, Wilson, and Johnson (2007) propose using data on suicide as a revealed preference (outcome-based) measure of well-being and find strong evidence that reference-group income negatively affects suicide risk. In this paper, we compare and contrast the empirical patterns of SWB and suicide data. We find that the two have very little in common in aggregate data (time series and cross-sectional), but have a strikingly strong relationship in terms of their determinants in individual-level, multivariate regressions. This latter result cross-validates suicide and SWB micro data as useful and complementary indicators of latent utility.

This study explores the macroeconomic implications of adaptive expectations in a standard growth model. We show that the self-confirming equilibrium under adaptive expectations is the same as the steady state rational expectations equilibrium for all admissible parameter values, but that dynamics around the steady state are substantially different between the two equilibria. The differences are driven mainly by the dampened wealth effect and the strengthened intertemporal substitution effect, not by escapes emphasized by Williams (2003). Consequently, adaptive expectations can be an important source of frictions that amplify and propagate technology shocks and seem promising for generating plausible labor market dynamics.

Previous research suggests that loan officers play a critical role in relationship lending by producing soft information about SMEs. For the first time, we empirically confirm this hypothesis We also examine whether the role of loan officers differs from small to large banks as predicted by Stein (2002). While we find that small banks produce more soft information, the capacity and manner in which loan officers produce soft information does not seem to differ between large and small banks. This suggests that, although large banks may produce more soft information, they likely tend to concentrate their resources on transactions lending.

This paper assesses whether partial exchange rate pass-through to trade prices has important implications for the prospective adjustment of global external imbalances. To address this question, we develop and estimate an open-economy DGE model in which pass-through is incomplete due to the presence of local currency pricing, distribution services, and a variable demand elasticity that leads to fluctuations in optimal markups. We find that the overall magnitude of trade adjustment is similar in a low and high pass-through world with more adjustment in a low pass-through world occurring through a larger response of the exchange rate and terms of trade rather than real trade flows.

This paper investigates the changing pattern and efficacy of sterilization within emerging market countries as they liberalize markets and integrate with the world economy. We estimate the marginal propensity to sterilize foreign asset accumulation associated with net balance of payments inflows, across countries and over time. We find that the extent of sterilization of foreign reserve inflows has risen in recent years to varying degrees in Asia as well as in Latin America, consistent with greater concerns about the potential inflationary impact of reserve inflows. We also find that sterilization depends on the composition of balance of payments inflows.

Modern corporate finance theory argues that although bank monitoring is beneficial to borrowers, it also allows banks banks to use the private information they gain through monitoring to "hold-up" borrowers for higher interest rates. In this paper, we seek empirical evidence for this information hold-up cost. Since new information about a firm's credit-worthiness is revealed at the time of its first issue in the public bond market, it follows that after firms undertake their bond IPO, banks with an exploitable information advantage will be forced to adjust their loan interest rates downwards, particularly for firms that are revealed to be safe. Our findings show that firms are able to borrow from banks at lower interest rates after they issue for the first time in the public bond market and that the magnitude of these savings is larger for safer firms. We further find that among safe firms, those that get their first credit rating at the time of their bond IPO benefit from larger interest rate savings than those that already had a credit rating when they entered the bond market. Since more information is revealed at the time of the bond IPO on the former firms and since this information will increase competition from uninformed banks, these findings provide support for the hypothesis that banks price their informational monopoly. Finally, we find that while entering the public bond market may reduce these informational rents, it is costly to firms because they have to pay higher underwriting costs on their IPO bonds. Moreover, IPO bonds are subject to more underpricing than subsequent bonds when they first trade in the secondary bond market.

Recent research suggests that there has been a decline in the extent to which firms "pass through" changes in exchange rates to prices. Beyond providing further evidence in support of this claim, this paper proposes an explanation for the phenomenon. It then presents empirical evidence of a structural break during the 1990s in the relationship between the real exchange rate and CPI inflation for a set of 14 OECD countries. It is suggested that the recent reduction in the real exchange rate pass-through can be attributed in part to the low-inflation environment of the 1990s.

We use a hedonic framework to estimate and simulate the impact of global warming on real estate prices at North American ski resorts. To do so, we combine data on resort-area housing values from two sources--data on average values for U.S. Census tracts across a broad swath of the western U.S. and data on individual home sales for four markets in the western U.S. and Canada, each available over multiple decades--with detailed weather data and characteristics of ski resorts in those areas. Our OLS and fixed-effects models of changes in home values with respect to medium-run changes in the share of snowfall in winter precipitation yield precise and consistent estimates of positive snowfall effects on housing values in both data sources. We use our estimates to simulate the impact of likely climate shifts on home values in coming decades and find substantial variation across resort areas based on climatic characteristics such as longitude, elevation, and proximity to the Pacific Ocean. Resorts that are unfavorably located face likely large negative effects on home prices due to warming, unless adaptive measures are able to compensate for the deterioration of conditions in the ski industry.

A number of studies have recently noted that monetary integration in the European Monetary Union (EMU) has been accompanied by increased financial integration. This paper examines the channels through which monetary union increased financial integration, using international panel data on bilateral international commercial bank claims from 1998-2006. I decompose the relative increase in bilateral commercial bank claims among union members following monetary integration into three possible channels: A "borrower effect," as a country's EMU membership may leave its borrowers more creditworthy in the eyes of foreign lenders; a "creditor effect," as membership in a monetary union may increase the attractiveness of a nation's commercial banks as intermediaries, perhaps through increased scale economies enjoyed by commercial banks themselves or through an improved regulatory environment after the advent of monetary union; and a "pairwise effect," as joint membership in a monetary union increases the quality of intermediation between borrowers and creditors when both are in the same union. This pairwise effect could be attributed to mitigated currency risk stemming from monetary integration, but may also indicate that monetary union integration increases borrowing capacity. I decompose the data into a series of difference-in-differences specifications to isolate these three channels and find that the pairwise effect is the primary source of increased financial integration. This result is robust to a number of sensitivity exercises used to address concerns frequently associated with difference-in-differences specifications, such as serial correlation and issues associated with the timing of the intervention.

The literature appears to have reached a consensus that financial globalization has had a "disciplining effect" on monetary policy, as it has reduced the returns from--and hence the temptation for--using monetary policy to stabilize output. As a result, monetary policy over recent years has placed more emphasis on stabilizing inflation, resulting in reduced inflation and greater output stability. However, this consensus has not been accompanied by convincing empirical evidence that such a relationship exists. One reason is likely to be that de facto measures of financial globalization are endogenous, and that instruments for financial globalization are elusive. In this paper, I introduce a new instrument, financial remoteness, as a plausibly exogenous instrument for financial openness. I examine the relationship between financial globalization and median inflation levels over an 11 year cross-section from 1994 through 2004, as well as a panel of 5-year median inflation levels between 1980 and 2004. The results confirm a negative relationship between median inflation and financial globalization in the base specification, but this relationship is sensitive to the inclusion of conditioning variables or country fixed effects, precluding any strong inferences.

This paper examines the robustness characteristics of optimal control policies derived under the assumption of rational expectations to alternative models of expectations formation and uncertainty about the natural rates of interest and unemployment. We assume that agents have imperfect knowledge about the precise structure of the economy and form expectations using a forecasting model that they continuously update based on incoming data. We also allow for central bank uncertainty regarding the natural rates of interest and unemployment. We find that the optimal control policy derived under the assumption of perfect knowledge about the structure of the economy can perform poorly when knowledge is imperfect. These problems are exacerbated by natural rate uncertainty, even when the central bank's estimates of natural rates are efficient. We show that the optimal control approach can be made more robust to the presence of imperfect knowledge by deemphasizing the stabilization of real economic activity and interest rates relative to inflation in the central bank loss function. That is, robustness to the presence of imperfect knowledge about the economy provides an incentive to employ a "conservative" central banker. We then examine two types of simple monetary policy rules from the literature that have been found to be robust to model misspecification in other contexts. We find that these policies are robust to the alternative models of learning that we study and natural rate uncertainty and outperform the optimal control policy and generally perform as well as the robust optimal control policy that places less weight on stabilizing economic activity and interest rates.

This paper develops a general equilibrium model to examine the quantitative effects of speculative bubbles on capital accumulation, growth, and welfare. A near-rational bubble component in the model equity price generates excess volatility in response to observed technology shocks. In simulations, intermittent equity price run-ups coincide with positive innovations in technology, investment and consumption booms, and faster trend growth, reminiscent of the U.S. economy during the late 1920s and late 1990s. The welfare cost of speculative bubbles depends crucially on parameter values. Bubbles can improve welfare if risk aversion is low and agents underinvest relative to the socially-optimal level. But for higher levels of risk aversion, the welfare cost of bubbles is large, typically exceeding one percent of annual consumption.

The Svensson generalization of the popular Nelson-Siegel term structure model is widely used by practitioners and central banks. Unfortunately, like the original Nelson-Siegel specification, this generalization, in its dynamic form, does not enforce arbitrage-free consistency over time. Indeed, we show that the factor loadings of the Svensson generalization cannot be obtained in a standard finance arbitrage-free affine term structure representation. Therefore, we introduce a closely related generalized Nelson-Siegel model on which the no-arbitrage condition can be imposed. We estimate this new arbitrage-free generalized Nelson-Siegel model and demonstrate its tractability and good in-sample fit.

Empirical evidence indicates that the elasticity of capital-labor substitution for the aggregate U.S. economy is below unity. In contrast, the existing indeterminacy literature has mostly restricted attention to a Cobb-Douglas production function which imposes a substitution elasticity exactly equal to unity. This paper examines the quantitative relationship between capital-labor substitution and the conditions needed for equilibrium indeterminacy (and belief-driven fluctuations) in a one-sector growth model. With variable capital utilization, the substitution elasticity has little quantitative impact on the minimum degree of increasing returns needed for indeterminacy. However, when capital utilization is constant, a below-unity substitution elasticity sharply raises the minimum degree of increasing returns. In this version of the model, lower substitution elasticities impose a higher adjustment cost on labor hours that cannot be mitigated by shifts in the capital utilization rate. Overall, our results show that empirically-plausible departures from the Cobb-Douglas specification can make indeterminacy more difficult to achieve.

This paper examines the robustness characteristics of optimal control policies derived under the assumption of rational expectations to alternative models of expectations. We assume that agents have imperfect knowledge about the precise structure of the economy and form expectations using a forecasting model that they continuously update based on incoming data. We find that the optimal control policy derived under the assumption of rational expectations can perform poorly when expectations deviate modestly from rational expectations. We then show that the optimal control policy can be made more robust by deemphasizing the stabilization of real economic activity and interest rates relative to inflation in the central bank loss function. That is, robustness to learning provides an incentive to employ a "conservative" central banker. We then examine two types of simple monetary policy rules from the literature that have been found to be robust to model misspecification in other contexts. We find that these policies are robust to empirically plausible parameterizations of the learning models and perform about as well or better than optimal control policies.

At the center of the financial market crisis of 2007-2008 was a highly unusual jump in spreads between the overnight inter-bank lending rate and term London inter-bank offer rates (Libor). Because many private loans are linked to Libor rates, the sharp increase in these spreads raised the cost of borrowing and interfered with monetary policy. The widening spreads became a major focus of the Federal Reserve, which took several actions--including the introduction of a new term auction facility (TAF)--to reduce them. This paper documents these developments and, using a no-arbitrage model of the term structure, tests various explanations, including increased risk and greater liquidity demands, while controlling for expectations of future interest rates. We show that increased counterparty risk between banks contributed to the rise in spreads and find no empirical evidence that the TAF has reduced spreads. The results have implications for monetary policy and financial economics.

Dramatic declines in capital tax rates among U.S. states and European countries have been linked by many commentators to tax competition and an inevitable "race to the bottom." This paper provides an empirical analysis of the reaction of capital tax policy in a given U.S. state to changes in capital tax policy by other states. The analysis is undertaken with a novel panel data set covering the 48 contiguous U.S. states for the period 1965 to 2006 and is guided by the theory of strategic tax competition. The latter suggests that capital tax policy is a function of "foreign" (out-of-state) tax policy, home state and foreign state economic and demographic conditions and, perhaps most importantly, preferences for government services. We estimate this reaction function for the two primary business tax policies employed by states: the investment tax credit rate and the corporate income tax rate. The slope of the reaction function--the equilibrium response of home state to foreign state tax policy--is negative, contrary to many prior empirical studies of fiscal reaction functions. This seemingly paradoxical result is due to two critical elements--controlling for aggregate shocks and allowing for delayed responses to foreign tax changes. Omitting either of these elements leads to a misspecified model and a positively sloped reaction function. Our results suggest that the secular decline in capital tax rates, at least among U.S. states, reflects synchronous responses among states to common shocks rather than competitive responses to foreign state tax policy. While striking given prior findings in the literature, these results are not surprising. The negative sign is fully consistent with qualitative and quantitative implications of the theoretical model developed in this paper. Rather than "racing to the bottom," our findings suggest that states are "riding on a seesaw."

This paper identifies factors associated with takeoff--a sustained period of high growth following a period of stagnation. We examine a panel of 241 "stagnation episodes" from 146 countries, 54% of these episodes are followed by takeoffs. Countries that experience takeoffs average 2.3% annual growth following their stagnation episodes, while those that do not average 0% growth; 46% of the takeoffs are "sustained," i.e. lasting 8 years or longer. Using probit estimation, we find that de jure trade openness is positively and significantly associated with takeoffs. A one standard deviation increase in de jure trade openness is associated with a 55% increase in the probability of a takeoff in our default specification. We also find evidence that capital account openness encourages takeoff responses, although this channel is less robust. Measures of de facto trade openness, as well as a variety of other potential conditioning variables, are found to be poor predictors of takeoffs. We also examine the determinants of nations achieving sustained takeoffs. While we fail to find a significant role for openness in determining whether or not takeoffs are sustained, we do find a role for output composition: Takeoffs in countries with more commodity-intensive output bundles are less likely to be sustained, while takeoffs in countries that are more service-intensive are more likely to be sustained. This suggests that adverse terms of trade shocks prevalent among commodity exports may play a role in ending long-term high growth episodes.

This paper shows that proximity to major international financial centers seems to reduce business cycle volatility. In particular, we show that countries that are further from major locations of international financial activity systematically experience more volatile growth rates in both output and consumption, even after accounting for domestic financial depth, political institutions, and other controls. Our results are relatively robust in the sense that more financially remote countries are more volatile, though the results are not always statistically significant. The comparative strength of this finding is in contrast to the more ambiguous evidence found in the literature.
