In this study we analyze the relationship between heat events and mortality in Germany. The main research questions are: Does heat lead to rising mortality and if yes, are the effects persistent or compensated for in the near future? Furthermore, we consider differences between heat effects in...

In this paper we specialize the Ngai-Pissarides model of growth and structural change [American Economic Review 97 (2007), 429-443] to the case of three sectors, representing the primary (agriculture, mining), secondary (construction, manufacturing) and tertiary (services) sectors. On that basis...

This work investigates the interrelation between production efficiency and population size of German cities. The productive efficiency in this context is the scale efficiency, which is a result of positive and negative agglomeration externalities. The investigation is performed in a two-stage...

This study presents the results of an extensive Monte Carlo experiment to compare different methods of efficiency analysis. In addition to traditional parametric-stochastic and nonparametric-deterministic methods recently developed robust nonparametric-stochastic methods are considered. The...

Many theoretical models show that redistribution causes low growth or capital outflows even though empirically redistribution and growth are often found to be positively associated across countries. This paper argues that tax competition and the danger of capital outflows leads optimizing...

We assume that some consistent estimator of an equilibrium relation between non-stationary fractionally integrated series is used in a first step to compute residuals (or differences thereof). We propose to apply the semiparametric log-periodogram regression to the (differenced) residuals in...

Since financial derivatives are key instruments for risk taking as well as risk reduction, it is only straightforward to examine their role in currency crises. This paper addresses this issue by investigating the impact of currency futures trading on the underlying exchange rates. After a...

It is obvious that the German economy exhibits a significant decline in economic growth during the last two decades. Although the German economy has still to overcome the burden of the reunification in 1990 it is shown that this burden might be only one reason of this decline. In this study we...

This paper investigates whether entrepreneurs with technical education are more innovative in high-tech industries than economists. The main contribution to the literature is in using the type of education as main explanatory variable for innovation. To analyze this question, the KfW/ZEW...
