We propose a simple method to help researchers develop quantitative models of economic fluctuations. The method rests on the insight that many models are equivalent to a prototype growth model with time-varying wedges which resemble productivity, labor and investment taxes, and government...

The New-Keynesian aggregate supply derives from micro-foundations an inflation-dynamics model very much like the tradition in the monetary literature. Inflation is primarily affected by: (i) economic slack; (ii) expectations; (iii) supply shocks; and (iv) inflation persistence. This paper...

This paper develops a model of unemployment fluctuations. The model keeps the architecture of the general-disequilibrium model of Barro and Grossman (1971) but takes a matching approach to the labor and product markets instead of a disequilibrium approach. On the product and labor markets, both...

The paper extends Woodford's (2000) analysis of the closed economy Phillips curve to an open economy with both commodity trade and capital mobility. We show that consumption smoothing, which comes with the opening of the capital market, raises the degree of strategic complementarity among...

Barro (1991) and others find that growth and schooling are highly correlated across countries, with each additional year of 1960 enrollment associated with about .6% per year faster growth in per capita GDP from 1960 to 1990. In a model with finite-lived individuals who choose schooling,...

Corporate cash flows are highly volatile and strongly procyclical. We examine the asset-pricing implications of the sensitivity of corporate cash flows to economic shocks within a continuous-time model in which dividends are a stochastic fraction of aggregate consumption. We provide closed-form...

This paper uses the neoclassical growth model to examine the extent to which a tax cut pays for itself through higher economic growth. The model yields simple expressions for the steady-state feedback effect of a tax cut. The feedback is surprisingly large: for standard parameter values, half of...

We explore a hypothesis about the take-off in inflation that occurred in the early 1970s. According to the expectations trap hypothesis, the Fed was pushed into producing the high inflation out of a fear of violating the public's inflation expectations. We compare this hypothesis with the...

This paper surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates slowly across a population of agents who strategically interact in their use of information....

Living arrangements have changed enormously over the last two centuries. While the average American today lives in a household of only three people, in 1850 household size was twice that figure. Further, both the number of children and the number of adults in a household have fallen...
