As a result of the Balassa effect relative prices change rapidly between and within the euro countries. Thus it is impossible to find a common monetary policy that will result in price stability in all countries. Based on empirical estimates of the Balassa model, the paper calculates a minimum...

The view that high unemployment in West Germany and other European countries is caused by a path dependence effect - or hysteresis effect - is quite popular among economists. However, because of an identification problem, much of the empirical evidence for this hypothesis is not fu lly...

Decisions on the presence of seasonal unit roots in economic time series are commonly taken on the basis of statistical hypothesis tests. Some of these tests have absence of unit roots as the null hypothesis, while others use unit roots as their null. Following a suggestion by Hylleberg (1995)...

The eastern expansion of the EU resembles German unification in its mometousness. Whereas the latter led to a 26% increase in the population of the Federal Republic, the former will increase the population of the EU by 28% if all ten entry aspirants are accepted. A special problem will be posed...

Based on explicit present value calculations, the paper criticizes the view that the PAYGO system wastes economic resources. In present value terms, there is nothi ng to be gained from a transition to a funded system even though the latter offers a permanently higher rate of return. The sum of...
