External trade and monetary policy in a currency area

No 738, Temi di discussione (Economic working papers) from Bank of Italy, Economic Research and International Relations Area
For historical and geographical reasons, the member countries of the European Monetary Union (EMU) display different degrees of external trade openness. The paper lays out a model for a currency area composed of two regions. One region is more open to trade with a third country outside the area than the other. Using the utility-based loss function for the currency area, the optimal monetary policy is compared to the one for a homogeneous area. In the model with heterogeneity, the relative competitiveness across regions influences the extent to which shocks are transmitted to the area-wide inflation and output gap. Under a plausible calibration for the EMU, the optimal policy plan exhibits a stronger tendency towards currency area exchange rate stabilization than the one in the homogeneity case. Moreover, it is welfare-improving to forgo some area-wide inflation stabilization to dampen inflation differentials.
