A two-country model of oligopoly in general equilibrium is used to show how changes in market structure accompany the process of trade and capital market liberalisation. The model predicts that bilateral mergers in which low-cost firms buy out higher-cost foreign rivals are profitable under...

I explore the interactions between comparative, competitive and absolute advantage in a two-country model of oligopoly in general equilibrium. Comparative advantage always determines the direction of trade, but both competitive and absolute advantage affect resource allocation, trade patterns...

This paper presents a new model of oligopoly in general equilibrium and explores its implications for positive and normative aspects of international trade. Assuming "continuum-Pollak" preferences, the model allows for consistent aggregation over a continuum of sectors, in each of which a small...

Empirical evidence shows that R&D spending is highly correlated with firm productivity, highly concentrated among large firms, and responsive to trade liberalization. This paper develops a model of product upgrading with heterogeneous firms that captures these characteristics by allowing firms...

A 2-country model with two groups of agents, workers and capitalists is presented in which economic integration results in an initial phase of catch-up, where the less industrialised country experiences the rise in both capital and labour income. Then, after a certain level of integration has...

We study firm heterogeneity in a specific factors model to address the effect of factor mobility on reallocation gains from trade. A model is proposed with Melitz type firm heterogeneity with two sectors, two countries and two fixed factors and one factor mobile across sectors. Equilibrium in...

I study the influence of minimum quality standards in a partial-equilibrium model of vertical product differentiation and trade in which duopolistic firms face quality-dependent costs and compete in quality and price in two segmented markets. Three alternative standard setting arrangements are...

In a model of vertical product differentiation, duopolistic firms face qualitydependent costs and compete in quality and price in two segmented markets. Minimum quality standards, set according to the principle of Mutual Recognition, can be used to increase welfare. The results of the one-shot...
