Fiscal federalism may not be a panacea in a monetary union if it does not address the non-cooperative behaviour between fiscal policymakers. To prove this, we assess the relative merits of a fiscal federalism scheme in a monetary union and intergovernmental fiscal cooperation without such a...

This paper studies the design of the policy mix in a monetary union, that is, the institutional arrangement specifying the relationships between the various policymakers present in the union and the extent of their capacity of action. It is assumed that policymakers do not cooperate. Detailing...
