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...

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...

Existing theories of trade agreements suggest that GATT/WTO efforts to reign in export subsidies represent an inefficient victory for exporting governments that comes at the expense of importing governments. Building from the Cournot delocation model first introduced by Venables (1985), we...

We consider the purpose and design of the World Trade Organization (WTO) and its predecessor, GATT. We review recent developments in the relevant theoretical and empirical literature. And we describe the GATT/WTO architecture and briefly trace its historical antecedents. We suggest that the...

We consider the purpose and design of trade agreements in imperfectly competitive environments featuring firm-delocation effects. In both the segmented-market Cournot and the integrated-market monopolistic competition settings where these effects have been identified, we show that the only...
