This paper studies the institutional design of the coordination of macroeconomic stabilization policies within a monetary union in the framework of linear quadratic differential games. A central role in the analysis plays the partitioned game approach of the endogenous coalition formation...

We construct a dynamic stochastic general equilibrium model to study optimal monetary stabilization policy. Prices are fully flexible and money is essential for trade. Our main result is that if the central bank pursues a long-run price path, thereby controlling inflation expectations, it can...

This paper develops a dynamic stochastic general equilibrium model to examine the quantitative macroeconomic implications of countercyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity which is the particular market failure justifying policy...

In this paper we consider a number of key issues related to the policy coordination in a monetary union that has been recently discussed in the literature. To this end we propose a multi-country New-Keynesian model of a monetary union cast in the framework of linear quadratic differential games....

It is widely assumed that a common currency makes it desirable to have also a common fiscal policy. However, if fiscal policy is a source of shocks, independent national fiscal policies are generally preferable because they allow for risk diversification.

We examine the sources of macroeconomic economic fluctuations by estimating a variety of medium-scale DSGE models within a unified framework that incorporates regime switching both in shock variances and in the inflation target. Our general framework includes a number of different model features...

Strengthening potential output is high on the agenda for economic policy in the European Union. While there is widespread agreement that structural policies have a positive impact on long-term growth, there is a controversial discussion whether coordination of macroeconomic policies can...

Modelle der neu-keynesianischen Ökonomie geben eine Erklärung für die kurzfristige Nichtneutralität des Geldes. Als Erklärungsansatz dient hierbei die Annahme nominaler Rigiditäten auf dem Arbeits- und Gütermarkt. Der vorliegende Beitrag zielt auf einen Vergleich zweier Modelle der...
