This paper develops a model of the circumstances under which it is beneficial to participate in a currency area. The proposed two-country monetary model of trade with nominal rigidities encompasses the real and monetary arguments suggested by the optimum currency area literature: correlation of...

This paper contributes to the micro-foundation of money in centralized markets with idiosyncratic uncertainty. It shows existence of stationary monetary equilibria and ensures that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in a...

European monetary integration was one element in the process of financial market integration but by far not the only one. The paper traces the development of financial markets and systems in Europe from the beginnings of the euromarkets in the 1950s over early exchange rate arrangements and the...

We analyze whether financial integration will lead to lower national regulation of domestic banking activities. In our model, banks' efforts and public regulation can lower the probability of bankruptcy. We contrast the national case with an integrated banking market and find that banks will...

Der Beitrag analysiert die Geschichte der europäischen Währungsintegration aus politisch-ökonomischer Sicht. Es wird gezeigt, dass die Währungsunion weniger auf politische Faktoren als auf den Einfluss wichtiger wirtschaftlicher Interessengruppen zurückgeführt werden muss. Die Logik der...

This paper studies the importance of money for inflation in the euro area. An inflation equation is derived from a small model that combines the supply and demand for money with a Phillips curve and the assumption that inflation expectations develop adaptively. The model's solution attributes an...

According to most academics and policymakers, transparency in monetary policymaking is desirable. I examine this proposition in a small theoretical model emphasizing forwardlooking private sector behavior. Transparency makes it easier for price setters to infer the central bank's future policy...

Conventional wisdom says that commitment eliminates the inflationary bias of monetary policy. However, this paper shows that the inflation bias can persist even when the central bank commits. A simple model is presented in which the central bank precommits by setting the policy instrument, and...

We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables. The form of model uncertainty our framework encompasses includes : simple...

In a surprisingly growing number of regions in Germany private "regional currencies" are issued as a cash substitute for the euro. Currently, these regional currencies are conceived almost exclusively as Schwundgeld (depreciative currency), which loses value on a predetermined timescale. This...
