The purpose of this paper is twofold. First, we present a new model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this framework can be...

We analyze the possibility and consequences of coalition-formation amongst suppliers of retail services. We first provide a framework in which producers of Substitutes have an incentive to Cluster in market places in order to attract consumers dispersed in space. Owing to spatial externalities,...

This paper presents evidence that, in Europe, production of high-tech goods is attracted to large markets, while R&D activities tend to be located away from them. In order to explain this phenomenon, we develop a two-country general equilibrium model where firms make separate choices about the...

We develop a two-country general equilibrium model where firms make separate choices about the location of R&D and high-tech production. There are two agglomeration forces: R&D spillovers and backward linkages associated with high-tech production. The latter tends to attract production to the...

This paper shows that the degree of competition affects the current account response to nominal shocks. The mechanism hinges on the relationship between the mark-up and the degree of real rigidity of prices. In a model with intermediate goods, the degree of real rigidity increases in the markup....

The New Trade Theory predicts that international trade lowers prices for consumers and expands the choices available to them. This study shows that both predictions may no longer hold once adjustments in the retail sector are taken into account. I present a new model of retailing in general...

In this paper, we study the effects of government debt on macroeconomic aggregates in a non-Ricardian framework. We develop a micro-founded framework which combines time-varying markups, endogenous labor supply and overlapping generations based on infinitely-lived families. The main contribution...

We depart from the trade and wages literature and its emphasis on North-South trade, examining North-North by developing the basic linkages between trade-based integration and relative wages in an Ethier-type division of labor model. Using this model we identify a formal relationship between...

The effects of competition on growth are analyzed in the recent literature by comparing economies with the same market structure but different degrees of substitutability. In this note, we show that in a general equilibrium model with monopolistic competition – la Dixit- Stiglitz the effect of...

Based on a model with imperfectly competitive labor and product markets the real consequences of labor market shocks for economies with either an earnings-related or flatrate unemployment compensation system are considered. A distinctive feature of the analysis is the comparison of both...
