This paper studies ethnic discrimination in Germany’s labour market with a correspondence test. We send two similar applications to each of 528 advertisements for student internships, one with a Turkish-sounding and one with a German-sounding name. A German name raises the average probability of a callback by about 14%. Differential treatment is particularly strong and significant in smaller firms at which the applicant with the German name receives 24% more callbacks. Discrimination disappears when we restrict our sample to applications including reference letters which contain favourable information about the candidate’s personality. We interpret this finding as evidence for statistical discrimination.

We show that, in a two-stage model of monetary policy with stochastic policy targets and asymmetric information, the transparency regime chosen by the central bank does never coincide with the regime preferred by society. Independent of society’s endogenous choice of delegation, the central bank reveals its inflation target and conceals its output target. In contrast, society would prefer either transparency or opacity of both targets. As a conclusion, the choice of the transparency regime should be part of the optimal delegation solution.

This paper uses panel data to show that capital controls have a significant impact on international interest rate differentials. Various types of controls can be distinguished within the data. The analysis shows that the aforementioned effects of capital controls on interest rates are especially strong in the case of capital import controls on portfolio capital; the implementation of these controls has been suggested in the wake of the Asian Crisis to prevent further crises. The results presented herein contradict the hypothesis that capital controls can achieve a restructuring of the maturity of capital inflows without a distortion in international capital allocation.

Courts are an important element in the institutional framework of labor markets, often determining the degree of employment protection. German labor courts provide a vivid example in this regard. However, we know relatively little about court behavior. A unique dataset on German labor court verdicts reveals that social and other criteria like employee characteristics, the type of job, local labor market conditions and court composition influence court decisions. At least as striking is that workers’ chances to win depend on where and when their cases are filed. This generates considerable ex ante uncertainty about outcomes.

This paper uses the adaptive Lasso estimator to determine variables important for economic growth. The adaptive Lasso estimator is a computationally very efficient procedure that simultaneously performs model selection and parameter estimation. The computational cost of this method is negligibly small compared with standard approaches in the growth regressions literature. We apply this method for a regional dataset for the European Union covering the 255 NUTS2 regions in the 27 member states over the period 1995-2005. The results suggest that initial GDP per capita (with an implied convergence speed of about 1.5% per annum), human capital ( proxied by the shares of highly and medium educated in the working age population), structural labor market characteristics (the initial unemployment rate and the initial activity rate of the low educated) as well as being a capital region are important for economic growth.

This paper analyzes the persistence of inflation in the euro area and, in particular, whether the persistence properties have changed since the start of European Monetary Union(EMU). For that purpose, we compare pre- and post-EMU inflation persistence, use rolling-window estimates of persistence, and apply tests specifically designed to detect break dates near the end of the sample period. In contrast to previous research, we find that inflation persistence has fallen significantly since the start of EMU. Persistence of consumer price inflation, which is central to the European Central Bank’s policy mandate, has fallen more than the persistence of deflator inflation. The drop in inflation persistence is consistent with the results from a simulated small New Keynesian model with a shift toward a more aggressive monetary policy stance.

The quantity theory of money, Okun’s law, and the Phillips curve are cornerstones of macroeconomic theory. But are they also of practical relevance? Using survey data for the euro area, we found that professional economists’ forecasts are consistent with a version of the quantity theory in which forecasts of the growth rate of money supply correlate in a proportional way with forecasts of the inflation rate. We also found that forecasts of changes in the unemployment rate and forecasts of the growth rate of real output are consistent with Okun’s law. Evidence of a systematic link between forecasts of the inflation rate and forecasts of the unemployment rate, however, is not strong.
