How to Manage Financial Shocks : Intra-European vs. International Monetary Coordination

Using a four-country Mundell-Fleming model including portfolio and wealth effects, we explore the question whether some types of policy coordination could improve the outcomes of a financial shock like the Asian crisis. Time-consistent equilibria are computed: a Nash equilibrium, a target zone regime and a coalition solution. The best equilibrium for all authorities except the US government is the European coalition. Introducing a Stability Pact in Europe does not alter this result. Introducing a Fed less conservative than the ECB or the BoJ provokes a change in US preferences: both authorities give priority to the target zone regime
