Economic analysis for a general audience

Jens H.E. Christensen and Glenn D. Rudebusch


Interest rates during the current economic recovery have been unusually low. Some have argued that yields have been pushed down by declines in longer-run expectations of the normal inflation-adjusted short-term interest rate—that is, by a drop in the so-called equilibrium or natural rate of interest. New evidence from financial markets shows that a decline in this rate has indeed contributed about 2 percentage points to the general downward trend in yields over the past two decades.

The latest in economic research

U.S. output has expanded only slowly since the recession trough in 2009, even though the unemployment rate has essentially returned to a precrisis, normal level. We use a growth-accounting decomposition to explore explanations for the output shortfall, giving full treatment to cyclical effects that, given the depth of the recession, should have implied unusually fast growth. We find that the growth shortfall has almost entirely reflected two factors: the slow growth of total factor productivity, and the decline in labor force participation. Both factors reflect powerful adverse forces that are largely unrelated to the financial crisis and recession—and that were in play before the recession.
