Monetary Policy Interactions under Managed Exchange Rates

This paper studies monetary policy games in a two-period Mundell-Fleming model, under a regime of managed exchange rates. A regime of managed exchange rates is defined as one where exchange rates are pegged but bilateral parities can be changed from time to time. The paper argues that such a regime is the most appropriate description of the Bretton Woods system and many arrangements currently in existence. We show that Cournot-Nash equilibria under managed rates differ significantly from those under fixed or floating rates. Under managed rates the world-wide efficiency losses from lack of coordination are not equally shared by all countries.
