This paper looks at recent advances in the study of aggregate fluctuations. Our emphasis is on three prominent areas of research: the stochastic growth model, economies which exhibit macroeconomic complementarities and models that emphasize heterogeneity. Each section of the paper outlines the...

This paper develops an open-economy model of the business cycle. Thenominal prices in the model are flexible and monetary nonneutrality isdeveloped using information confusion about the sources of disturbances todemand coupled with differential persistence of demand shocks. Firms useinventories...

This paper examines business cycles theoretically and empirically, with a quantitative study based on experience over the long run and in a cross section of countries. Several major questions in business cycle theory are explored. Theoretical concerns indicate that the properties of business...

The purpose of this paper is to construct a quantitative equilibrium model with price setting and use it to ask whether staggered price setting can generate persistent output fluctuations following monetary shocks. We construct a business cycle version of a standard sticky price model in which...

Measured productivity is strongly procyclical. Real business cycle theories suggest that actual fluctuations in productivity are the source of fluctuations in aggregate output. Keynesian theories maintain that fluctuations in aggregate output come from shocks to aggregate demand. Keynesian...

Multi-sector sticky price models have surprising implications when durable goods have flexible prices. While in actual data the production of virtually all durables exhibits strong negative responses to monetary contractions, in dynamic general equilibrium models a monetary contraction causes...

This paper shows that nominal price rigidity can arise from a failure to coordinate price changes. If a firm's desired price is increasing in others' prices, then the gains to the firm from adjusting its price after a nominal shock are greater if others adjust. This "strategic complementarity"...

Our purpose in this paper is to present a class of convex endogenous growth models, and to analyze their performance in terms of both growth and business cycle criteria. The models we study have close analogs in the real business cycle literature. In fact, we interpret the exogenous growth rate...

Recent work by David Lilien has argued that the existence of a strong positive correlation between the dispersion of employment growth rates across sectors (G) and the unemployment rate implies that shifts in demand from some sectors to others are responsible for a substantial fraction of...

According to Austrian macroeconomic theory, capital accumulation today generates supply tomorrow. Will that supply match tomorrows demand? In this paper we study this question in a multi-good and risky environment with an efficient financial system. Towards this end we develop a model based on...
