Recent efforts by international trade economics have led to the integration of the theory of the multinational enterprise into the theory of international trade. This is both an exciting and an important development. Prior to the last decade or so, analysis of the MNE was largely distinct from...

International trade economists made seminal contributions to general equilibrium theory, moving away from an emphasis on existence of equilibrium to algebraic formulations which enabled us to characterize key relationships between parameters and variables, such as that between tariffs and...

Foreign producer services can provide substantial benefits for domestic firms. We build on earlier monopolistic-competition models of intermediate producer services in this paper. Results show that: (1) while foreign services are partial-equilibrium substitutes for domestic skilled labour, they...

Classic trade questions are reconsidered by generalizing a factor-proportions model to multiple countries, multi-stage production, and country-specific trade costs. We derive patterns of production specialization and trade for a matrix of countries that differ in relative endowments (columns)...

An interesting empirical phenomenon is export-platform foreign-direct investment, particularly affiliate production for sale in third countries rather than in the parent or host countries. This is rather poorly understood because our theoretical understanding of multinationals is largely derived...

There has been much discussion about what issues should be included in international 'trade' negotiations. Different countries, firms, and activist groups have quite different views regarding which items should (or should not) be negotiated together. Proposals run the gamut from no linking to...

Recent theoretical developments have incorporated endogenous multinational firms into the general-equilibrium model of trade. One simple taxonomy separates the theory into "vertical" models, in which firms geographically separate activities by stages of production, and "horizontal" models, in...

Export-platform foreign direct investment in which the affiliate's output is (largely) sold in third markets rather than in the parent or host markets has received empirical attention recently, but little theoretical analysis. This paper is an attempt to make some sense of this phenomenon. We...
