The rise of offshoring of intermediate inputs raises important questions for commercial policy. Do the distinguishing features of offshoring introduce novel reasons for trade policy intervention? Does offshoring create new problems of global policy cooperation whose solutions require...

We provide a first formal analysis of the international rules that govern the use of subsidies to domestic production. Our analysis highlights the impact of the new subsidy disciplines that were added to GATT rules with the creation of the WTO. While GATT subsidy rules were typically viewed as...

The authors propose a unified theoretical framework within which to interpret and evaluate the foundational principles of GATT. Working within a general equilibrium trade model, they represent government preferences in a way that is consistent with national income maximization but also allows...

According to the terms-of-trade theory, negotiations over tariffs alone, coupled with an effective market access preservation rule, can bring governments to the efficiency frontier. In this paper, we show that the nature of international price determination is important for this central result...

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...

According to the terms-of-trade theory, governments use trade agreements to escape from a terms-of-trade-driven prisoner's dilemma. We use the terms-of-trade theory to develop a relationship that predicts negotiated tariff levels on the basis of pre-negotiation data: tariffs, import volumes and...

This paper examines how estimates of the deterrent effect of capital punishment depend on alternate choices of assumptions concerning the homicide process. Specific models of the homicide process represent bundles of these assumptions, which involve the unobserved heterogeneity, the relevant...
