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 combine original geo-referenced data on mining extraction of 15 minerals with information on conflict events at spatial resolution of 0.5o x 0.5o for all Africa over 1997-2010. Exploiting exogenous variations in world prices, we find a positive impact of mining on conict at the local level....

This paper uses detailed information on the latitude and longitude of conflict events in Sub-Saharan African countries to study the impact of external income shocks on the likelihood of violence. We consider a number of external demand shocks faced by the countries or the regions within...

This paper studies empirically the impact of mining on conflicts in Africa. Using novel data, we combine geo-referenced information over the 1997-2010 period on the location and characteristics of violent events and mining extraction of 27 minerals. Working with a grid covering all African...

Using a French firm-level database that combines balance-sheet and product-destination-specific export information over the period 1995-2001, we study the interconnections between exports and domestic sales. We identify exogenous shocks that affect the firms' demand on foreign markets to...
