To what extent must nations cede control over their economic and social policies if global efficiency is to be achieved in an interdependent world? This question is at the center of the debate over the future role of GATT (and its successor, the WTO) in the realm of labor and environmental...

This paper considers self-enforcing trade agreements among privately informed governments. A trade agreement that uses weak bindings (i.e., maximal tariff levels) is shown to offer advantages relative to a trade agreement that uses strong bindings (i.e., precise tariff levels). Consistent with...

We study the implications of customs union formation for multilateral tariff cooperation. We model cooperation in multilateral trade policy as self-enforcing, in that it involves balancing the current gains from deviating unilaterally from an agreed-upon trade policy against the future losses...

We present a theory of collusive pricing in markets subject to business cycle fluctuations. In the business cycle model that we adopt, market demand alternates stochastically between fast-growth (boom) and slow-growth (recession) phases. We provide a complete characterization of the...

A prominent problem with the WTO dispute settlement procedures is the practical difficulty faced by small and developing countries in finding the capacity to effectively retaliate against trading partners that are in violation of their WTO commitments. In light of this problem, Mexico has...

How should the issue of domestic labor standards be handled in the GATT/ WTO? This question is part of a broader debate over the appropriate scope of international economic institutions such as the GATT, where member-countries are considering proposals for a new round of n3 negotiations that...

Empirical studies have repeatedly documented the countercyclical nature of trade barriers. In this paper, we propose a simple theoretical framework that is consistent with this and other empirical regularities in the relationship between protection and the business cycle. We examine the ability...

We describe recent work on the theory of trade agreements that speaks to the purpose and design of GATT. Our discussion proceeds in three steps. First, we examine the purpose of a trade agreement. In both the traditional economic and the political-economy approaches to the study of trade...

International disputes over subsidies are increasingly disrupting the world trading system. The creation of the WTO was nearly prevented by disputes in the Uruguay Round of GATT negotiations over the issue of negotiating disciplines on agricultural subsidies, an issue which continues to plague...

Why do governments seek restrictions on the use of export subsidies through reciprocal trade agreements such as GATT? With existing arguments, it is possible to understand GATT's restrictions on export subsidies as representing an inefficient victory of the interests of exporting governments...
