Reassessing Longer-Run U.S. Growth: How Low?
2016-18 | August 2016
abstract (+)What is the sustainable pace of GDP growth in the United States? A plausible point forecast is that GDP per capita will rise well under 1 percent per year in the longer run, with overall GDP growth of a little over 1-1/2 percent. The main drivers of slow growth are educational attainment and demographics. First, rising educational attainment will add less to productivity growth than it did historically. Second, because of the aging (and retirements) of baby boomers, employment will rise more slowly than population (which, in turn, is projected to rise slowly relative to history). This modest growth forecast assumes that productivity growth is relatively “normal,” if modest—in line with its pace for most of the period since 1973. An upside risk is that we see another burst of information-technology-induced productivity growth similar to what we saw from 1995 to 2004.
The Outlook for U.S. Labor-Quality Growth
2016-14 | With Bosler, Daly, and Hobijn | July 2016
abstract (+)Over the past 15 years, labor-quality growth has been very strong—defying nearly all earlier projections—and has added around 0.5 percentage points to an otherwise modest U.S. productivity picture. Going forward, labor quality is likely to add considerably less and may even be a drag on productivity growth in the medium term. Using a variety of methods, we project that potential labor-quality growth in the longer run (7 to 10 years out) is likely to fall in the range of 0.1 to 0.25 percent per year. In the medium term, labor-quality growth could be lower or even negative, should employment rates of low-skilled workers make a cyclical rebound towards pre-recession levels. The main uncertainties in the longer run are whether the secular decline in employment of low-skilled workers continues and whether the Great Recession pickup in educational attainment represents the start of a new boom or is simply a transitory reaction to a poor economy.
Why Has the Cyclicality of Productivity Changed? What Does It Mean?
2016-07 | With Wang | April 2016
abstract (+)U.S. labor and total factor productivity have historically been procyclical—rising in booms and falling in recessions. After the mid-1980s, however, TFP became much less procyclical with respect to hours while labor productivity turned strongly countercyclical. We find that the key empirical “fact” driving these changes is reduced variation in factor utilization—conceptually, the workweek of capital and labor effort. We discuss a range of theories that seek to explain the changes in productivity’s cyclicality. Increased flexibility, changes in the structure of the economy, and shifts in relative variances of technology and “demand” shocks appear to play key roles.
Does the United States have a Productivity Slowdown or a Measurement Problem?
2016-03 | With Byrne and Reinsdorf | March 2016
abstract (+)After 2004, measured growth in labor productivity and total factor productivity (TFP) slowed. We find little evidence that the slowdown arises from growing mismeasurement of the gains from innovation in information-technology (IT)-related goods and services. First, mismeasurement of IT hardware is significant prior to the slowdown and because the domestic production of these products has fallen, the quantitative effect on productivity is larger in the 1995-2004 period than since, despite mismeasurement worsening for some types of IT. Hence, our adjustments make the slowdown in labor productivity worse. The effect on TFP is more muted. Second, many of the tremendous consumer benefits from smartphones, Google searches, and Facebook are, conceptually, non-market: Consumers are more productive in using their nonmarket time to produce services they value. These benefits raise consumer well-being but do not imply that market-sector production functions are shifting out more rapidly than measured. Moreover, estimated gains in non-market production are too small to compensate for the loss in overall well-being from slower market-sector productivity growth. In addition to IT, other measurement issues we can quantify (such as increasing globalization and fracking) are also quantitatively small relative to the slowdown.
Is China Fudging its Figures? Evidence from Trading Partner Data
2015-12 | With Hsu and Spiegel | September 2015
abstract (+)How reliable are China’s GDP and other data? We address this question by using trading-partner exports to China as an independent measure of its economic activity from 2000-2014. We find that the information content of Chinese GDP improves markedly after 2008. We also consider a number of plausible, non-GDP indicators of economic activity that have been identified as alternative Chinese output measures. We find that activity factors based on the first principal component of sets of indicators are substantially more informative than GDP alone. The index that best matches activity in-sample uses four indicators: electricity, rail freight, an index of raw materials supply, and retail sales. Adding GDP to this group only modestly improves in-sample performance. Moreover, out of sample, a single activity factor without GDP proves the most reliable measure of economic activity.
Shocks and Adjustments
2013-32 | With Daly, Jorda, and Nechio | July 2017
abstract (+)The manner firms respond to shocks reflects fundamental features of labor, capital, and commodity markets, as well as advances in finance and technology. Such features are integral to constructing models of the macroeconomy. In this paper we document secular shifts in the margins firms use, in aggregate, to adjust to shocks that have consequences for the economy’s cyclical behavior. These new business cycle facts on the comovement of output and its inputs are a natural complement to analyzing output and its expenditure components. Our findings shed light on the changing cyclicality of productivity in response to different shocks.
A Quarterly, Utilization-Adjusted Series on Total Factor Productivity
2012-19 | April 2014
abstract (+)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).

Sector-Specific Technical Change
Manuscript | With Basu, Fisher, and Kimball | November 2013
abstract (+)Theory implies that the economy responds differently to technology shocks that affect the production of consumption versus investment goods. We estimate industry-level technology innovations and use the input-output tables to relax the typical assumptions in the investment-specific technical change literature—assumptions that, we find, do not hold in the data.
We find that investment-technology improvements are sharply contractionary for hours, investment, consumption, and output. Consumption-technology improvements, on the contrary, are generally expansionary. Thus, disaggregating technology shocks into consumption and investment-specific changes yields two shocks that both produce business-cycle comovement, and also explain a large fraction of annual changes in GDP and its components. Most of the responses we find are consistent with the predictions of simple two-sector models with sticky prices.

Why Has the Cyclicality of Productivity Changed? What Does It Mean?

The Pre-Great Recession Slowdown in Productivity
European Economic Review 88(C), April 2016, 3-20 | With Cette and Mojon
abstract (+)In the years since the Great Recession, many observers have highlighted the slow pace of productivity growth around the world. For the United States and Europe, we highlight that this slow pace began prior to the Great Recession. The timing thus suggests that it is important to consider factors other than just the deep crisis itself or policy changes since the crisis. For the United States, at the frontier of knowledge, there was a burst of innovation and reallocation related to the production and use of information technology in the second half of the 1990s and the early 2000s. That burst ran its course prior to the Great Recession. Continental European economies were falling back relative to that frontier at varying rates since the mid-1990s. We provide VAR and panel-data evidence that changes in real interest rates have influenced productivity dynamics in this period. In particular, the sharp decline in real interest rates that took place in Italy and Spain seem to have triggered unfavorable resource reallocations that were large enough to reduce the level of total factor productivity, consistent with recent theories and firm-level evidence.
Monetary Policy Effectiveness in China: Evidence from a FAVAR Model
Journal of International Money and Finance, July 2014 | With Spiegel and Swanson
abstract (+)We use a broad set of Chinese economic indicators and a dynamic factor model framework to estimate Chinese economic activity and inflation as latent variables. We incorporate these latent variables into a factor-augmented vector autoregression (FAVAR) to estimate the effects of Chinese monetary policy on the Chinese economy. A FAVAR approach is particularly well-suited to this analysis due to concerns about Chinese data quality, a lack of a long history for many series, and the rapid institutional and structural changes that China has undergone. We find that increases in bank reserve requirements reduce economic activity and inflation, consistent with previous studies. In contrast to much of the literature, however, we find that changes in Chinese interest rates also have substantial impacts on economic activity and inflation, while other measures of changes in credit conditions, such as shocks to M2 or lending levels, do not once other policy variables are taken into account. Overall, our results indicate that the monetary policy transmission channels in China have moved closer to those of Western market economies.

Productivity and Potential Output Before, During, and After the Great Recession
In NBER Macroeconomics Annual, ed. by Parker, Woodford, 2014
abstract (+)U.S. labor and total-factor productivity growth slowed prior to the Great Recession. The timing rules explanations that focus on disruptions during or since the recession, and industry and state data rule out “bubble economy” stories related to housing or finance. The slowdown is located in industries that produce information technology (IT) or that use IT intensively, consistent with a return to normal productivity growth after nearly a decade of exceptional IT-fueled gains. A calibrated growth model suggests trend productivity growth has returned close to its 1973-1995 pace. Slower underlying productivity growth implies less economic slack than recently estimated by the Congressional Budget Office. As of 2013, about ¾ of the shortfall of actual output from (overly optimistic) pre-recession trends reflects a reduction in the level of potential.

Labor Markets in the Global Financial Crisis: The Good, the Bad and the Ugly
National Institute Economic Review 228: R58-R64, May 2014 | With Nechio, Daly, and Jorda
abstract (+)This note examines labor market performance across countries through the lens of Okun’s Law. We find that after the 1970s but prior to the global financial crisis of the 2000s, the Okun’s Law relationship between output and unemployment became more homogenous across countries. These changes presumably reflected institutional and technological changes. But, at least in the short term, the global financial crisis undid much of this convergence, in part because the affected countries adopted different labor market policies in response to the global demand shock.
The Future of U.S. Economic Growth
American Economic Review 104(5), May 2014, 44-49 | With Jones
abstract (+)Modern growth theory suggests that more than 3/4 of growth since 1950 reflects rising educational attainment and research intensity. As these transition dynamics fade, U.S. economic growth is likely to slow at some point. However, the rise of China, India, and other emerging economies may allow another few decades of rapid growth in world researchers. Finally, and more speculatively, the shape of the idea production function introduces a fundamental uncertainty into the future of growth. For example, the possibility that artificial intelligence will allow machines to replace workers to some extent could lead to higher growth in the future.
Growth Accounting with Misallocation: Or, Doing Less with More in Singapore
American Economic Journal: Macroeconomics 3, April 2011, 29-74
abstract (+)We show that in a two-sector economy with heterogeneous capital subsidies and monopoly power, primal and dual measures of TFP growth can diverge from each other as well as from true technology. These distortions give rise to dynamic reallocation effects that imply technology growth needs to be measured from the bottom up rather than from the top down. Using Singapore as an example, we show how incomplete data can be used to estimate aggregate and sectoral technology growth as well as reallocation effects. Our framework can reconcile divergent TFP estimates in Singapore and can resolve other empirical puzzles regarding Asian development.
What Do We Know (and Not Know) about Potential Output?
FRB St Louis Review 91(4), July 2009, 187-213 | With Basu
abstract (+)Potential output is an important concept in economics. Policymakers often use a one-sector neoclassical model to think about long-run growth, and they 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 the long run, the one-sector model falls short empirically, reflecting the importance of rapid technological 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 the authors to discuss a range of other issues that are less well understood and where further research could be valuable.
A General-Equilibrium Asset-Pricing Approach to the Measurement of Nominal and Real Bank Output
In Price Index Concepts and Measurement, 70, ed. by E. Diewert, J. Greenlees, and C. Hulten | Chicago: University of Chicago Press for NBER, 2009. 273-320 | With Basu and Wang
abstract (+)This paper addresses the proper measurement of financial service output that is not priced explicitly. It shows how to impute nominal service output from financial intermediaries’ interest income, and how to construct price indices for those financial services. We present an optimizing model with financial intermediaries that provide financial services to resolve asymmetric information between borrowers and lenders. We embed these intermediaries in a dynamic, stochastic, general-equilibrium model where assets are priced competitively according to their systematic risk, as in the standard consumption- capital- asset-pricing model. In this environment, we show that it is critical to take risk into account in order to measure financial output accurately. We also show that even using a risk-adjusted reference rate does not solve all the problems associated with measuring nominal financial service output. Our model allows us to address important outstanding questions in output and productivity measurement for financial firms, such as: (1) What are the correct “reference rates” one should use in calculating bank output? (2) If reference rates need to take account of risk, does this mean that they must be ex ante rates of return? (3) What is the right price deflator for the output of financial firms? Is it just the general price index? (4) When–if ever–should we count capital gains of financial firms as part of financial service output?
Trend Breaks, Long-Run Restrictions, and Contractionary Technology Improvements
Journal of Monetary Economics 54(8), November 2007, 2467-2485
abstract (+)Structural vector autoregressions with long-run restrictions are extraordinarily sensitive to low-frequency correlations. Recent literature finds that the estimated effects of technology shocks are sensitive to how one treats hours per capita. However, after allowing for (statistically and economically significant) trend breaks in productivity, results are much less sensitive: hours fall when technology improves. The issue is that the common high-low-high pattern of productivity growth and hours (i.e., the low-frequency correlation) inevitably leads to a positive estimated response. The trend breaks control for this correlation. This example suggests a practical need for care in using long-run restrictions.

Information and Communications Technology as a General-Purpose Technology: Evidence from U.S Industry Data
German Economic Review 8(2), May 2007, 146-173 | With Basu
abstract (+)Many people point to information and communications technology (ICT) as the key for understanding the acceleration in productivity in the United States since the mid-1990s. Stories of ICT as a ‘general-purpose technology’ suggest that measured total factor productivity (TFP) should rise in ICT-using sectors (reflecting either unobserved accumulation of intangible organizational capital; spillovers; or both), but with a long lag. Contemporaneously, however, investments in ICT may be associated with lower TFP as resources are diverted to reorganization and learning. We find that U.S. industry results are consistent with general-purpose technology (GPT) stories: the acceleration after the mid-1990s was broad-based–located primarily in ICT-using industries rather than ICT-producing industries. Furthermore, industry TFP accelerations in the 2000s are positively correlated with (appropriately weighted) industry ICT capital growth in the 1990s. Indeed, as GPT stories would suggest, after controlling for past ICT investment, industry TFP accelerations are negatively correlated with increases in ICT usage in the 2000s.
Are Technology Improvements Contractionary?
American Economic Review 96(5), December 2006, 1418-1448 | With Basu and Kimball
abstract (+)Yes. We construct a measure of aggregate technology change, controlling for aggregation effects, varying utilization of capital and labor, nonconstant returns, and imperfect competition. On impact, when technology improves, input use and nonresidential investment fall sharply. Output changes little. With a lag of several years, inputs and investment return to normal and output rises strongly. The standard one-sector real-business-cycle model is not consistent with this evidence. The evidence is consistent, however, with simple sticky-price models, which predict the results we find: when technology improves, inputs and investment generally fall in the short run, and output itself may also fall.

The Case of the Missing Productivity Growth: Or, Does Information Technology Explain Why Productivity Accelerated in the United States but Not the United Kingdom?
NBER Macroeconomics Annual, 2003 | With Basu, Oulton, and Srinivasan
abstract (+)We argue that unmeasured investments in intangible organizational capital associated with the role of information and communications technology (ICT) as a general purpose technology’ can explain the divergent U.S. and U.K. TFP performance after 1995. GPT stories suggest that measured TFP should rise in ICT-using sectors, perhaps with long lags. Contemporaneously, investments in ICT may in fact be associated with lower TFP as resources are diverted to reorganization and learning. In both the U.S. and U.K., we find a strong correlation between ICT use and industry TFP growth. The U.S. results, in particular, are consistent with GPT stories: the TFP acceleration was located primarily in ICT-using industries and is positively correlated with industry ICT capital growth from the 1980s and early 1990s. Indeed, as GPT stories suggest, controlling for past ICT growth, industry TFP growth appears negatively correlated with increases in ICT capital services in the late 1990s. A somewhat different picture emerges for the U.K. TFP growth does not appear correlated with lagged ICT capital growth. But TFP growth in the late 1990s is strongly and positively associated with the growth of ICT capital services, while being strongly and negatively associated with the growth of ICT investment.
