The paper analyses the common European monetary policy based on a Mises-Hayek overinvestment framework, which is combined with the theory of optimum currency areas. It shows how since the turn of the millennium a too expansionary monetary policy contributed to unsustainable overinvestment booms...

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...

The euro area will not have a centralised budget and smoothing of country-specific asymmetric shocks via private financial markets will develop only slowly. Mistrust among the governments has caused rigid, even pro-cyclical fiscal policies. Smoothing mechanisms are absent due to the fear that...

What policy objective should a common central bank in a heterogeneous monetary union pursue? Should it base its decisions on the EU-wide average of inflation and growth or should it instead focus on (appropriately weighted) national welfare losses based on national rates of inflation and growth?...

It is widely debated whether a monetary union has to be accompanied by a fiscal transfer scheme to accommodate asymmetric shocks. We build a model of a monetary union with a central bank and two heterogeneous countries that are linked by a fiscal transfer scheme with repercussions on monetary...

Membership in a monetary union implies stronger incentives for nominal wage flexibility in the form of wage indexation and shorter contract length than nonmembership. For example, entry into a monetary union may cause a move from a non-indexation to an indexation equilibrium. But more wage...

The paper addresses the question what effects the enlargement of a monetary union will have on necessary structural refoms in the (low distortion) member countries and the (high distortion) candidate country. While monetary union lowers reforms in the candidate country, members of the monetary...

The combination of discretionary monetary policy, labor-market distortions and nominal wage rigidity yields an inflation bias as monetary policy tries to exploit nominal wage contracts to address labour-market distortions Although an inflation target eliminates this inflation bias, it creates a...

This paper quantifies the welfare differences among a monetary union, flexible exchange rates (economic disintegration) and a monetary plus fiscal transfer union (higher economic integration). The vehicle of analysis is a medium-scale New Keynesian DSGE model consisting of two heterogeneous...

In a monetary union, the interaction between several governments and a single central bank is plagued by several sources of deficit bias, including common pool problems. Each government has strong preferences over local spending and taxation but suffers only part of the costs of union-wide...
