What is the optimal institutional structure for an independent central bank? The paper shows when it will be optimal for a country to have a central bank to be organized according to federal, purely national or a combination of both aspects. The analysis is then extended to a supranational...

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 rates of inflation and growth? We find that a central bank 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...

We analyze the similarities and the differences in the fragility of the European Monetary system (EMS) and the Eurozone. We test the hypothesis that in the EMS the fragility arose from the absence of a credible lender of last resort in the foreign exchange markets while in the Eurozone it was...

The paper examines the monetary-fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. We first show that monetary uncertainty disciplines fiscal policymakers and thereby reduces taxes, average inflation and output distortions. However, as more...

This paper employs a stylized New Keynesian DSGE model for a monetary union to analyze whether cyclical inflation differentials can be explained by cross-country differences concerning the characteristics of financial markets. Our results suggest that empirically plausible degrees of...

As shown in Sinn and Wollmershäuser (2012a), during the European balance-of-payments crisis, inter-governmental credit and Target credit granted by core-country central banks have replaced private international capital flows in financing the crisis countries' current account deficits, and even...

Europe’s monetary union is part of a broader process of integration that started in the aftermath of World War II. In this “political guide for economists” we look at the creation of the euro within the bigger picture of European integration. How and why were European institutions...

International comparisons show that countries with co-ordinated wage setting generally have lower unemployment than countries with less co-ordinated wage setting. This paper argues that the monetary regime may affect whether co-ordination among many wage setters is feasible. A strict monetary...
