The classical and early neoclassical economists knew that the essential function of money was its role as a medium of exchange; Recently, this idea has been formalized using search-theoretic noncooperative equilibrium models of the exchange process. The goal of this paper is to use a simple model...

A long standing issue in macroeconomics is that of the relation of imperfect competition to fluctuations in output. In this paper we examine the relation between monopolistic competition and the role of aggregate demand in the determination of output. We first show that monopolistically...

This paper is a theoretical study into how credit constraints interact with aggregate economic activity over the business cycle.
