This paper analyses the customs union problem in a model containing a continuum of products. The continuum is in three dimensions, so that three countries each have a distinct comparative advantage. Trade patterns are endogenously determined, and changed by policy. This is in the tradition of...

This paper surveys four ex-post quantitative studies of the effect of United Kingdom accession to the European Economic Countries on trade in manufactures. It starts by discussing the principal predictions of economic theory, establishing a framework for measuring integration effects, and...

The Zollverein was arguably the most important free-trade agreement of the 19th century. This paper investigates the economic impact of the Zollverein on trade in Germany. Although 1834 is the official date of the Zollverein's establishment, member states in fact joined in a non-random sequence...

We study a model in which a customs union trades with countries that behaved strategically. If the members of the customs union are similar but not identical, one country will want to delegate authority for making union policy to its partner. Even if side-payments within the union are permitted,...

How are the benefits - and costs - of a customs union divided between member countries? Outcomes depend on the comparative advantage of member countries, relative to each other and to the rest of the world. Countries with a comparative advantage between that of their partners and the rest of the...

In general, a reduction in trade barriers will affect the environment by expanding the scale of economic activity, by altering the composition of economic activity and by initiating a change in the techniques of production. We present empirical evidence to assess the relative magnitudes of these...

This paper considers the location effects of geographically-discriminatory trade policy. A preferential move towards a customs union attracts industry to the integrating countries. When internal barriers fall below some critical level, input-output links between imperfectly competitive firms...

Regional integration is on the rise again, despite its apparent failure among developing countries in the past. The paper first surveys the ambiguous economics of customs unions. We emphasize that the traditional dichotomy between `trade creation' and `trade diversion' is not particularly...

Using an extension of the influence-driven lobbying approach developed by Grossman and Helpman, we study the impact of regional integration arrangements (RIAs) on trade policy towards non-members in a three-good, three-country model. We explore under what conditions the formation of an RIA...

This paper explores the links between international trade theory and the practice of trade and industrial policy in open economies, with special attention to three areas where theoretical lessons have been misunderstood in policy debates. It argues that the ‘concertina rule’ for tariff...
