Fixed exchange rates and non-cooperative monetary policies

This paper presents a model which in a world with fixed exchange rates and absence of capital controls non-cooperative game yield multiple Nash equilibria with nonoptimal allocations, when we introduce regimes as strategies for the players. In general there is a unique Perfect Equilibrium for the game with both strategies. The sub-optimality of the non-cooperative solution provides scope for international coordination, in the form of joint choice of non-inflationary polices that dominate the Nash equilibria allocations.
