The paper discusses the policy problems of a project aimed at substituting several national currencies with one single currency. While these problems are of general interest, the analysis is motivated by the plan for Economic and Monetary Union among the members of the European Community. The...

This paper studies the equilibrium determination of the number of political jurisdictions in different political regimes, democratic or not, and in different economic environments, with more or less economic integration. We focus on the trade off between the benefits of large jurisdictions in...

Migrants from a population with heterogeneous intergenerational discount rates will be self-selected on intergenerational altruism. Thus, immigrants may be...

Using cross-country and Russian household survey data, we assess six possible explanations for this...

Delays at the border for customs clearance are seemingly a central feature of the trade regime in the CIS states. Here, we argue that with queuing costs being endogenously determined in such circumstances tariff liberalization (even in the small economy case) can be welfare worsening since...
