Evaluating interest rate rules in an estimated DSGE model
The empirical DSGE (dynamic stochastic general equilibrium) literature pays surprisingly little attention to the behavior of the monetary authority. Alternative policy rule specifications abound, but their relative merit is rarely discussed. We contribute to filling this gap by comparing the fit of a large set of interest rate rules (fifty-five in total), which we estimate within a simple New Keynesian model. We find that specifications in which monetary policy responds to inflation and to deviations of output from its efficient level?the one that would prevail in the absence of ...
Okun’s Law and Long Expansions
Economic forecasters frequently use a simple rule of thumb called Okun's law to link their real GDP growth forecasts to their unemployment rate forecasts. While they recognize that temporary deviations from Okun's law may occur, forecasters often assume that sustained reductions in the unemployment rate require robust GDP growth. However, our analysis suggests that Okun's law has not been a consistently reliable tool for predicting the size of declines in the unemployment rate during the last three expansions—a finding that reflects the impact of changes in the labor market since the early ...
Has U.S. Monetary Policy Tracked the Efficient Interest Rate?
Interest rate decisions by central banks are universally discussed in terms of Taylor rules, which describe policy rates as responding to inflation and some measure of the output gap. We show that an alternative specification of the monetary policy reaction function, in which the interest rate tracks the evolution of a Wicksellian efficient rate of return as the primary indicator of real activity, fits the U.S. data better than otherwise identical Taylor rules. This surprising result holds for a wide variety of specifications of the other ingredients of the policy rule and of approaches to ...
The Great Moderation, Forecast Uncertainty, and the Great Recession
The Great Recession of 2007-09 was a dramatic macroeconomic event, marked by a severe contraction in economic activity and a significant fall in inflation. These developments surprised many economists, as documented in a recent post on this site. One factor cited for the failure to anticipate the magnitude of the Great Recession was a form of complacency affecting forecasters in the wake of the so-called Great Moderation. In this post, we attempt to quantify the role the Great Moderation played in making the Great Recession appear nearly impossible in the eyes of macroeconomists.
