The effects of entry and exit by monopolistically competitive intermediate goods producers on equilibrium business cycles are analyzed in the presence of internal returns to scale and external returns to specialization. In the environment studied, market power and endogenous entry and exit, in...

Strategic interaction among oligopolistic innovators and its implications for economic growth are examined in two dynamic computable general equilibrium models. In each environment, technologies for producing a final good are such that the profits of any intermediate good producer depend on the...

An environment capable of generating both counter- and procyclical movements in markups through the interaction of opposing factors is considered. This framework can account for observed variations in the cyclical behavior of markups across industries. Technology shocks and endogenous labor...

We study the responses of real and nominal prices to random flutuations in costs and money growth using a monetary search economy in which there are no costs or temporal restrictions on sellers' ability to change prices. The economy exhibits a form of price stickiness in that the price level may...

The short-run non-neutrality of money and its implications for inflation dynamics are examined in a monetary search economy with heterogeneous agents. Lump-sum money injections affect the distribution of money holdings in equilibrium and thus generate short-run non-neutrality. The response of...

We study a monetary search economy in which endogenous fluctuations in market power driven by changes in consumers' search intensity determine the extent of price adjustment to movements in productivity and the money growth rate. A calibrated version of the economy exhibits countercyclical...

This paper examines the transitional dynamics of economic integration in the two country endogenous growth model of Rivera-Batiz and Romer (1991) and in an extension by Rivera-Batiz and Xie (1992). It is shown that, in the absence of knowledge flows across countries economic integration will...

There are at least two versions of the Law of One Price under the assumptions of perfect competition, no trade barriers, and no transport costs. One version predicts equal prices of competing goods sold in the same country and manufactured by producers located in different countries. Another...
