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...

We explain the recent events in the German market for online access using a model of a regulated monopoly renting phone lines to retailers. Retailers offer either a linear or a flat tariff to consumers. Consumer heterogeneity leads to adverse selectiion. We show why market entry for flatrate...

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 fully...

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)...
