This paper presents a two-country dynamic general equilibrium model with imperfect competition and nominal price rigidities in which terms of trade shocks coexist with inefficient supply shocks. We first analyse the features of the optimal cooperative plan. While terms of trade shocks should be offset by movements in the exchange rate, inefficient supply shocks are more likely to make a case for a fixed exchange rate regime. Surprisingly, we show that the optimal cooperative solution can be implemented at decentralized level through inflation-targeting regimes. Under these regimes each monetary authority weighs only domestic targets, namely GDP inflation and output gap. Even if there are gains from cooperation, inward looking monetary policymakers can achieve the first best
