Almost twenty-five years after the appearance of Dixit and Stiglitz’s paper on monopolistic competition and optimum product diversity, I try to take stock of the progress which has been made in applying their approach to international trade theory. I review the principal applications to trade...

This paper analyses levels of low literacy across twelve countries using the International Adult Literacy Survey. We go beyond existing work that only looks at the proportions below certain critical levels of literacy. Using methods developed for the measurement of poverty we calculate measures...

This paper extends the theory of multinational corporations, identifying three distinct influences of internal trade liberalisation by a group of countries on the level and pattern of inward foreign direct investment (FDI). First, the tariff-jumping motive encourages plant consolidation. Second,...

This paper endogenises the extent of intra-sectoral competition in a multi-sectoral model of oligopoly in general equilibrium. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand behaviour,...

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...

I outline the effect of business networks on trade, FDI and wel- fare in a two-country, two-firm duopoly. The network effect, following Greaney (2002), is modelled as a marginal cost disadvantage facing a firm from Foreign in selling to Home. Unlike traditional trade costs, this cost cannot be...

This paper studies the strategic behavior of multinationals towards weak labor standards in developing countries (South). Without a marginal cost pricing policy, abundant labor in the South gives firms the power to set wages through their choice of output. A strategic reduction in output offsets...

Geographical diversification describes the degree to which a firm’s operations in a particular industry are dispersed across countries. This paper presents evidence on the geographical diversification within the EU of the 290-odd largest manufacturing firms in Europe. We also explore how...

Since firm heterogeneity has been introduced into international trade models, the importance of firm entry and exit (the extensive margin) has been highlighted. In fact, Chaney (2008) illustrates how accounting for this extensive margin and heterogenous firms alters the standard gravity...
