This paper develops a monetary-fiscal game which stresses the importance of international spillovers and introduces a double (monetary and fiscal) credibility problem. The first part of the paper shows that the welfare cost of structural distortions is increased by the inability of fisical policymakers to commit, whereas the welfare cost of stochastic shocks is increased by international spillovers. The second part of the paper studies the welfare consequences of the monetary union. It is shown that the welfare impact of EMU for Europe is ambiguous, but that EMU is welfare-improving for the US.
