This paper shows how distance may be used to coordinate on a unique equilibrium in which trade agreements are regional. Trade agreement formation is modeled as coalition formation. In a standard trade model with no distance between countries, a familiar problem of coordination failure arises...

The GATT/WTO Article XXIV prevents a customs union (CU) from raising its common external tariff. In this paper, we compare CU formation with and without this Article XXIV constraint. We show, in a multi-country oligopoly model, that for a given CU structure, Article XXIV improves world welfare...

This paper develops a model of a trade agreement that puts at centre stage the competing interests between ?rms within a sector: Larger ?rms tend to be pro-trade liberalization whereas smaller ?rms favor protection. This set-up contrasts with the prior literature in economics that has tended to...

This paper shows that the WTO's Article XXIV increases the likelihood of free trade, but may worsen world welfare when free trade is not reached and customs unions (CUs) form. We consider a model of many countries. Article XXIV prevents a CU from raising its common external tariff, which makes...

In an international trading economy where countries set tariffs strategically, modeled using a Cobb-Douglas example, this paper studies the relationship between the structure and the performance of the world market. Using new results from monotone comparative statics in a Shapley-Shubik market...

This paper shows how the institutional rules imposed on its signatories by the GATT created a strategic incentive for countries to liberalize gradually. Trade liberalization must be gradual, and free trade can never be achieved, if punishment for deviation from an agreement is limited to a...

This paper argues that free trade agreements (FTAs) are regional because, in their absence, optimal tariffs are higher against (close) regional partners than (distant) countries outside the region. Optimal tariffs shift rents from foreign firms to domestic citizens. Lower transport costs imply...

This paper identifies a new terms-of-trade externality that is exercised through tariff setting. A North-South model of international trade is introduced in which the number of countries in each region can be varied. As the number of countries in one region is increased, each government there...
