A real business cycle model with heterogeneous agents is parameterized, calibrated, and simulated to see if it can account for some stylized facts characterizing postwar U.S. business cycle fluctuations, such as the countercyclical movement of labor’s share of income, and the acyclical...

As part of a fiscal stimulus package, some members of Congress have recently proposed a temporary investment subsidy. This paper uses the neoclassical growth model to evaluate the likely macroeconomic effects of such a subsidy. The model predicts a 0.8 percentage point increase in output growth...

When U.S. steel corporations began declaring bankruptcy and laying off thousands of workers, tariffs on foreign steel seemed a reasonable way of preventing further damage to the industry. But why do most economists favor free trade?

Recent monetary history has been characterized by monetary authorities that appear to shift periodically between distinct policy regimes associated with higher or lower average rates of money creation. As policy regimes are not directly observable and as the rate of monetary expansion varies for...

A chief goal of the Pigou cycle literature is to generate a boom in response to news of a future increase in productivity, and a bust if this improvement does not in fact take place. We nd that monetary policy can generate Pigou cycles in a two sector model with durables and non-durables, and...

Based on a two sector dynamic new Keynesian model with sticky prices, this paper makes two contributions to the Pigou cycle literature. First, the paper quantifies the contribution of `news shocks' -- signals of future productivity changes. Maximum likelihood estimates indicate that nondurable...

Several approaches to finding the second-order approximation to a dynamic model have been proposed recently. This paper differs from the existing literature in that it makes use of the Magnus and Neudecker (1999) definition of the Hessian matrix. The key result is a linear system of equations...

An investigation of whether economic theory supports the claim that a technology shock can change the "natural rate of unemployment."

Statistics that measure labor market activity, such as employment and unemployment, are often interpreted in the press and by politicians as measures of economic performance and social well-being. Discussions that focus on cross-country comparisons of unemployment, for example, seem to be based...
