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...

Why did inflation increase so dramatically from the 1960s to the 1970s? One possible theory is that once people started believing inflation would rise, the Fed was forced to validate those expectations by increasing the money supply. In "How Inflation Hawks Escape Expectations Traps," Sylvain...

Using survey data on expectations, the authors examine whether the post-war data are consistent with theories of a self-fulfilling inflation episode during the 1970s. Among commonly cited factors, oil and fiscal shocks do not appear to have triggered an increase in expected inflation that was...

Heightened uncertainty acts like a decline in aggregate demand because it depresses economic activity and holds down inflation. Policymakers typically try to counter uncertainty's economic effects by easing the stance of monetary policy. But, in the recent recession and recovery, nominal...

An equilibrium model is used to assess the quantitative importance of monetary policy for the post-1984 decline in U.S. inflation and output volatility. The principal finding is that monetary policy played a substantial role in reducing inflation volatility, but a small role in reducing real...

Heightened uncertainty acts like a decline in aggregate demand because it depresses economic activity and holds down inflation. Policymakers typically try to counter uncertainty's economic effects by easing the stance of monetary policy. But, in the recent recession and recovery, nominal...

Disagreement among economic forecasters about the future path of inflation has risen substantially since the start of the recession. The nature of this disagreement varies with the forecast time horizon, with some forecasters expecting much lower short-run inflation and others anticipating much...

This paper examines the incidence and welfare costs of inflation in the presence of financial market frictions and home production. The results suggest that financing constraints on firms' working capital expenditures significantly increase the welfare costs relative to the standard...

Ball (1997) shows using a small closed economy model that nominal GDP targeting can lead to instability. This paper extends Ball's model to uncover the role inflation expectations play in generating this instability. By changing the process by which inflation expectations are formed in the...

Central banks pay close attention to inflation expectations. In standard models, however, inflation expectations are tied down by the assumption of rational expectations and should be of little independent interest to policy makers. In this paper, we relax the assumption of rational expectations...
