We investigate the role of networks of military alliances in preventing or encouraging wars between groups of countries. A country is vulnerable to attack if there is some fully-allied group of countries that can defeat that country and its (remaining) allies based on a function of their...

International trade models typically assume that producers in one country trade directly with final consumers in another. In the real world, of course, trade can involve long chains of potentially independent actors who move goods through wholesale and retail distribution networks. These...

The increased integration of the economies of Central and Eastern Europe with the European Union (EU) as the Europe Agreements are progressively implemented, is projected to have a significant impact on trade flows with Spain, as exports and imports grow very rapidly, albeit starting from a very...

This paper argues that seasonal fluctuations in international trade are large and have non-trivial effects on a country's resource allocation, production, and welfare. Using U.S. quarterly data, we find fluctuations of as much as 43% and 15% for apparel imports and exports respectively, and 7%...

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 paper examines why ‘globaphobia’ seems to be more prevalent among labour in the United States than in Europe. It argues that globalization has generated more wealth, but also more income inequality and adjustment problems, in America than in Europe. In the United States, the median voter...

This paper seeks to integrate more closely the theory of optimum currency areas with the theory of international trade. The currency area is considered as a continuous variable ranging from zero to one: zero if there is no enlargement, and some positive value otherwise, corresponding exactly to...

This paper consits of two parts .. First part is a Static model..and models a globalised economy and observes the effects of sense of security between nations and the willingness of people to develop and cooperate.the Second part considers the world as a set of regions specialising in production...

For Africa, a regional customs union is unlikely to realise net welfare gains (in the sense of trade creation dominating trade diversion) which cannot be attained through unilateral trade liberalization. Unilateral reform has often failed in Africa, however. A regional customs union tied to...

We develop a model where trade liberalization leads to skill-biased technological change, which in turn raises the relative return to skilled labour. As firms get access to a larger market, they have incentives to choose a more skill-intensive technology because a lowering of variable costs...
