This paper provides evidence on monopolistic competition models with endogenous technology by studying the effects of sectoral export variety on country productivity. The effects are estimated in a translog GDP function system based on data for 34 countries from 1982 to 1997. Country...

Environmental economics has traditionally fallen in the domain of microeconomics, but recently approaches from macroeconomics have been applied to studying environmental policy. We focus on two macroeconomic tools and their application to environmental economics. First, real business cycle...

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation--in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to...

New Keynesian models of price setting under monopolistic competition involve two kinds of inefficiency: the price level is too high because firms ignore an aggregate demand externality, and when there are costs of changing prices, price stickiness may be an equilibrium response to changes in...

This paper explains prices, output and employment adjustment In an open economy characterized by a monopolistic competitive market structure where goods prices are flexible while wages are determined by contracts that pre-set the wage path for several periods. The paper solves the rational...

The purpose of this paper is to explain price and output dynamics in an open economy characterized by a monopolistic competitive market structure in which pricing decisions incur costs. That lead producers to pre-set the price path for several periods. The paper derives an optimal pricing rule,...

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...

The purpose of this paper is to explain deviations from PPP in an economy charaterived by a mononolistic competitive market structure in which pricing decisions incur costs. That lead producers to pre-set the price path for several periods. The paper derives an optimal pricing rule, including...

Much recent research in the economics of information has analyzed the implications of alternative market structures in the presence of qualitative characteristics which cannot be accurately and objectively measured or described. This approach avoids the more basic question of the influence of...

Motivated by the long-standing debate on the pros and cons of competitive devaluation, we propose a new perspective on how monetary and exchange rate policies can contribute to a country's international competitiveness. We refocus the analysis on the implications of monetary stabilization for a...
