This paper examines the magnitude of informational problems associated with the implementation and interpretation of simple monetary policy rules. Using Taylor's rule as an example, I demonstrate that real-time policy recommendations differ considerably from those obtained with ex post revised...

Theory restricts short-run job creation and destruction responses and cumulative employment and job reallocation responses to allocative and aggregate shocks. We formulate these restrictions and implement them for postwar data on U.S. manufacturing. Allocative shocks are the main driving force...

Using panel data for a large set of high-income, emerging market, developing, and transition countries, we find robust evidence that the large output loss from financial crises and some types of political crises is highly persistent. The results on financial crises are also highly robust to the...

We investigate the sources of the important shifts in the volatility of US macroeconomic variables in the postwar period. To this end, we propose the estimation of DSGE models allowing for time variation in the volatility of the structural innovations. We apply our estimation strategy to a...

Countercyclical risk aversion can explain major puzzles such as the high volatility of asset prices. Evidence for its existence is, however, scarce because of the host of factors that simultaneously change during financial cycles. We circumvent these problems by priming financial professionals...

The paper considers optimal monetary stabilization policy in a forward-looking model, when the central bank recognizes that private sector expectations need not be precisely model-consistent, and wishes to choose a policy that will be as good as possible in the case of any beliefs that are close...

I revisit the question of indeterminacy in US monetary policy using limited-information identification-robust methods. I find that the conclusions of Clarida, Galí, and Gernter (2000) that policy was inactive before 1979 are robust, but the evidence over the Volcker-Greenspan periods is...
