Kurzfassung auf Englisch:

This paper deals with potential instabilities of the eurozone stemming from an insufficien interplay between monetary policy and reform effort on the one hand and the emergence of intra-euro area divergences on the other. As a first step, we assess the effect of EMU on structural reform and investigate this question by an examination of the relationship between fixed exchange rates and reform in two wider samples of countries. We also stress that loose monetary conditions which prevailed until some months ago can also manifest themselves in asset price inflation, notably in the housing market. When these bubbles burst, for example, when housing prices stop rising, this often leads to a prolonged period of economic instability and weakness rather than consumer price inflation.
As a second step, we point out that risks for EMU are not only increasing because longer-term disequilibria become evident in fiscal and monetary policy, but also because serious divergences are now appearing within the euro area which threaten its long-term cohesiveness. The most manifest example of this threat comes from what promises to be a long-term divergence between Germany and
Italy which for the time being was offset by asynchronous developments of house
prices in both countries. There are still large differences within the euro area, with the small countries performing much better than the large ones on almost every indicator. This suggests that better policies can make a large difference even if monetary policy is the same for everybody.
Finally, we construct a simple formal model in order to investigate whether
EMU is in danger from internal tensions which could lead to severe instabilities. The experience so far has shown that some countries are continuously losing competitiveness. Is this a structural problem in the sense that these countries just have problems in keeping inflation at level that does not imply a continuing loss of competitiveness? Or is the persistence of higher inflation one can observe in some countries due to the internal dynamics of a monetary union in which any country that starts with higher inflation rate also has a lower real interest rate, which stimulates demand, and thus leads potentially to even more inflation. The purpose of our theoretical section is to discuss what the main factors are which could lead to such diverging cycles.
