This article describes three approximation methods I used to solve the growth model (Model 1) studied by the National Bureau of Economic Research's nonlinear rational-expectations-modeling group project, the results of which are summarized by Taylor and Uhling (1990). The methods involve...

It has been suggested that existing estimates of the long-run impact of a surprise move in income may have a substantial upward bias due to the presence of a trend break in postwar U.S. gross national product data. This article shows that the statistical evidence does not warrant abandoning the...

This paper develops the quantitative implications of optimal fiscal policy in a business cycle model. In a stationary equilibrium, the ex ante tax rate on capital income is approximately zero. The tax rate on labor income fluctuates very little and inherits the persistence properties of the...

Hours worked and the return to working are weakly correlated. Traditionally, the ability to account for this fact has been a litmus test for macroeconomic models. Existing real-business-cycle models fail this test dramatically. The authors modify prototypical real-business-cycle models by...

This paper studies P. Cagan's model of the German hyperinflation under the hypothesis that adaptive expectations are rational. It shows that inference about the key money demand elasticity parameter, a, is very senstitive to the specification of the dynamic interaction of the unobserved money...

This paper assesses the impact of a monetary policy shock on the U.S. economy. The authors' measures of contractionary monetary policy shocks are associated with a fall in various monetary aggregates and a rise in the federal funds rate, declines in different measures of real activity, and sharp...
