We develop a model of common agency with complete information and general preferences with nontransferable utility, and we prove that the principals' Nash equilibrium in truthful strategies implements an efficient action. We apply this theory to the construction of a positive model of public...

Whether governments clash in trade disputes or negotiate over trade agreements, their actions in the international arena reflect political conditions back home. Previous studies of cooperative and non-cooperative trade relations have focused on governments that are immune from political...

We develop a multicountry, dynamic general equilibrium model of product innovation and international trade to study the creation of comparative advantage through research and development and the evolution of world trade over time. In our model, firms must incur resource costs to introduce new...

In an economy with imperfect labor contracts, differences in the distribution of human capital are an independent source of comparative advantage. I study a world economy with two sectors, one where output is produced by teams and another where individuals can work alone. When worker’...

Paul Romer (1986, 1990) ve Robert Lucas (1988)’in makaleleri bize; ölçeðe göre artan getirilerin mevcut olduðu bir ekonomik ortamda yatýrým gerçekleþtiðinde, sermayenin marjinal ürününün iskonto oranýna göre zamanla düþmesi gerekmediðini hatýrlatmýþtýr. Zira sermaye...

We study patterns of foreign direct investment (FDI) in a multi-country world economy. We develop a model featuring non-homothetic preferences for quality and monopolistic competition in which specialization is purely demand-driven and the decision to serve foreign countries via exports or FDI...

The last decade has seen an important extension of the theory of international trade to include imperfectly competitive market structures. This book collects 19 of the most influential articles on trade with imperfect competition, providing ready access to current research by top-level...

We study the determinants of the location of subcontracted activity in a general equilibrium model of outsourcing and trade. We model outsourcing as an activity that requires search for a partner and relationship-specific investments that are governed by incomplete contracts. The extent of...

Price controls create opportunities for international arbitrage. Many have argued that such arbitrage, if tolerated, will undermine intellectual property rights and dull the incentives for investment in research-intensive industries such as pharmaceuticals. We challenge this orthodox view and...
