This study examines empirically factor mobility and distribution of economic activity under economic integration, with the result that the benchmark of the equal-share relationship holds strongly for US states and less so for EU countries, but does not hold for Developing Countries or the World....

We show that in a fully integrated economy, in which there is free mobility of goods and factors, each member’s share of total output will equal its shares of total stocks of productive factors (i.e., physical and human capital). We label this result the equal-share relationship. This...

We study the optimal trade policy against a foreign oligopoly withendogenous quality. We show that, under the Most Favoured Nation(MFN) clause, a uniform tariff policy is always welfare improvingover the free trade equilibrium. However, a nonuniform tariff policyis always desirable on welfare...

Forthcoming in the <I>International Economic Review</I>.<P> We examine an export game where two firms (home and foreign), located in two differentcountries, produce vertically differentiated products. The foreign firm is the most efficientin terms of R&D costs of quality development and the foreign...</p></i>

We build a simple theoretical model to understand why developing and transition economieshave increasingly applied anti-dumping laws. To that end, we investigate the strategic incentivesof oligopolistic exporting firms to undertake dumping in these economies. We show that dumpingmay be due to...

Anti-dumping actions are now the trade policy of choice of developing and transition economies. To understand why these economies have increasingly applied anti-dumping laws, we build a simple theoretical model of vertical intra-industry trade and investigate the strategic incentives of...
