This paper studies the determinants of TFPR, a revenue based measure of total factor productivity. Recent business cycle models are built upon the countercyclical dispersion of TFPR. But, the distribution of TFPR is endogenous, dependent upon other exogenous shocks and the endogenous...

A major unresolved issue in business cycle theory is the construction of an endogenous propagation mechanism capable of capturing the amount of persistence displayed in the data. In this paper we explore the quantitative implications of one propagation mechanism: learning by doing. Estimation of...

We analyze a financial collapse, such as the one which occurred during the Great Depression, from the perspective of a monetary model with multiple equilibria. The economy we consider contains financial fragility due to increasing returns to scale in the intermediation process. Intermediaries...

This paper explores cyclical fluctuations in investment due to discrete changes in the plant's stock of capital. To do so, we focus on a machine replacement problem in which a producer decides whether to replace its entire existing stock of capital with new machinery and equipment. This decision...

This paper explores the behavior of the U.S. economy during the interwar period from the perspective of a model in which the existence of non-convexities in the intermediation process gives rise to a multiplicity of equilibria. The resulting indeterminancy is resolved through a sunspot process...

We study the stochastic behavior of a dynamic general equilibrium model with monopolistic competition. Each seller sells his product in the consumption goods as well as the investment goods market and has market power in both. Consumers derive utility from a CES aggregate of all the consumption...

This paper studies an economy in which producers must incur resource costs to replace depreciated machines. The process of costly replacement and depreciation creates endogenous fluctuations in productivity, employment and output of a single producer. We also explore the spillover effects of...
