Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using...

This paper examines the interdependence between innovation and imports of intermediates, and their joint impact on productivity. We do so by developing a quantitative model with heterogeneous firms and international trade where firms can invest in R&D and source inputs internationally....

In order to study the costs/benefits of a monetary union between Germany and France, we attempt to go beyond a mere focus on asymmetries and examine what each country would have lost or gained had there been a common monetary policy. We try to identify the macroeconomic effects of such a change...

What are the prospects that risk sharing in EMU will ever attain the levels in the US? So far as the risk sharing in the US depends on interregional transfers through the budget of the federal government, those prospects are poor. So far as the risk sharing in the US takes place though market...

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 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,...

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...

We construct new series for common native language and common spoken language for 195 countries, which we use together with series for common official language and linguistic proximity in order to draw inferences about (1) the aggregate impact of all linguistic factors on bilateral trade, (2)...

It is generally assumed that distance in the gravity model strictly reflects frictions impeding bilateral trade. However, distances North-South could also reflect differences in factor endowment that provide opportunities for profitable trade. This paper investigates the hypothesis that if we...
