We develop a competitive model of trade between countries with similar aggregate factor endowments. The trade pattern reflects differences in the distribution of talent across the labor forces of the two countries. The country with a relatively homogeneous population exports the good produced by...

This paper develops a model of capacity-price competition in which the equilibrium outcome ranges from the Bertrand to the Cournot outcome as capacity constraints become more important. This model is employed to reexamine aspects of strategic-trade-policy theory and, in particular, the theory's...

The World Trade Organization (WFO) lacks the power to directly enforce agreements. It is, therefore, important to understand what role the WTO can play to facilitate international cooperation and whether a multilateral institution can offer distinct advantages over a web of bilateral agreements....

The Grossman-Helpman "Protection for Sale" model, concerning the political economy of trade protection, yields clear predictions for the cross-sectional structure of import barriers. Our objective is to check whether the predictions of the Grossman-Helpman model are consistent with the data and,...

We propose a model of trade agreements in which contracting is costly, and as a consequence the optimal agreement may be incomplete. In spite of its simplicity, the model yields rich predictions on the structure of the optimal trade agreement and how this depends on the fundamentals of the...

We present a model where trade agreements are motivated by the desire of governments to commit vis-à-vis domestic lobbies, in addition to standard terms-of-trade externalities. The model predicts that trade liberalization is deeper when capital is more mobile across sectors, and when...

In this paper we model contract incompleteness "from the ground up," as arising endogenously from the costs of describing the environment and the parties' behavior. Optimal contracts may exhibit two forms of incompleteness: discretion, meaning that the contract does not specify the parties'...

Some international organizations are governed by unanimity rule, others by (simple or qualified) majority rules. Standard voting models, which assume that the decisions made by voting are perfectly enforceable, have a hard time explaining the observed variation in governance mode, and in...
