Abstract (EN)

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 authori- ties 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.
