This chapter considers alternatives to the Armington formulation of international trade found in most computable general equilibrium (CGE) models. International trade structures consistent with the monopolistic competition models suggested by Krugman (1980) and Melitz (2003) are presented in a...

This paper investigates the consequences of the completion of the internal market in the EC using a computable general equilibrium model of trade under imperfect competition. The focus of the paper is the welfare consequences of reducing trade barriers and the changes in production and trade...

In this article we develop a simple analytically solvable model of heterogeneous firms. The heterogeneous firm framework presented in this paper is particularly suitable for the structural estimation of variety gains from trade integration, as all structural equations for empirical estimations...

Import competition from China is pervasive in the sense that for many good categories, the competitive environment that US firms face in these markets is strongly driven by the prices of Chinese imports, and so is their pricing decision. This paper quantifies the effect of the...

We investigate theoretically and empirically the competitive effects of increased trade on prices, productivity and markups. Using disaggregated data for EU manufacturing over the period 1988-2000 we find increased openness exerts a negative and significant impact on sectoral prices. Increased...

This paper analyses the consequences for the standard import allocation models of assuming monopolistic competition on the supply side. Together with relative prices, this requires additional variables to capture product differentiation effects. To this end, we derive a composite price index...

We examine the sales of French manufacturing firms in 113 destinations, including France itself. Several regularities stand out: (1) the number of French firms selling to a market, relative to French market share, increases systematically with market size; (2) sales distributions are very similar...

This paper reviews estimates of the effects of `1992' on international trade and welfare, and the policy implications of those estimates. It surveys earlier research starting with the Cecchini Report of 1988 and then summarizes some new results based on general equilibrium modelling with...
