Monetary union or currency competition? Currency arrangements for monetary stability in East and West

Recent events in the European Monetary System on the one hand and monetary disintegration in the former Soviet Union on the other hand have revived interest in the question of how to design and choose a monetary regime for both parts of Europe that ensures monetary stability. The objective of monetary stability can be achieved either by complete monetary union or by currency competition. Building on Hayek's ideas, I argue that both regimes are viable solutions depending on the circumstances. The paper first focuses on the misperceived benefits of flexible exchange rates, making the case for monetary union in Western Europe. However, monetary union is no alternative for Eastern Europe and the former Soviet Union. Instead currency competition could be used to retain the benefits of flexible exchange rates and to foster monetary stability at the same time.
