This paper employs worldwide data on output and bilateral trade in order to identify optimum currency areas (OCA’s) on a global basis. By retaining only two of the many criteria that have been mentioned in the literature on OCA’s, it has been possible to use computer programming to do the...

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...

In contrast to conventional analyses of monetary union between two particular countries or sets of countries, this paper treats the possible expansion of a given currency area as a continuous variable ranging from zero to one; zero if there is no expansion and one if all sources of imports and...

This paper integrates in a unified and tractable framework some of the key insights of the field of international trade and economic growth. It examines a sequence of theoretical models that share a common description of technology and preferences but differ on their assumptions about trade...

Cultural factors and especially common languages are well-known determinants of trade. By contrast, the knowledge of foreign languages was not explored in the literature so far. We combine traditional gravity models with data on fluency in the main languages used in EU and candidate countries....

In order to assess the costs of a European Monetary Union, we use a structural VAR approach based on the long-run identifying scheme pioneered by Blanchard and Quah and extended by others. We then apply the approach to as many EU members as data limitations permit: namely, Germany, Spain,...
