This paper develops a model of the breakup or unification of nations. In each nation the decision to separate is taken by majority voting. A basic trade-off between the efficiency gains of unification and the costs in terms of loss of control on political decisions is highlighted. The model...

Europe’s monetary union is part of a broader process of integration that started in the aftermath of World War II. In this “political guide for economists” we look at the creation of the euro within the bigger picture of European integration. How and why were European institutions...

This two-volume set provides fundamental analyses of the relations between cultural variables and economic performance. It encompasses indispensable contributions by economists and other influential social scientists in this growing interdisciplinary area.
