We estimate a linear and a piecewise linear Phillips curve model with regional labor market data for West German and Neue Länder. Employing regional observations allows us to country difference the data. This eliminates, under the assumption of homogeneous Länder, supply shocks and changes in...

Im folgenden soll versucht werden, empirische Evidenz zum Transmissionsmechanismus mit Hilfe monetärer Schocks zu generieren. Die quantitativen Auswirkungen der monetären Impulse werden mit Hilfe von Impuls-Antwort-Funktionen beschrieben, wobei die Impuls- Antwort-Funktionen auf einem VAR...

We estimate the impact of dollar changes on the value of German DAX corporations, using APT-modelling for the period 1977 - 1995. Several macroeconomic risk factors, including the dollar and a residual market factor representing the general market risk, are specified. The general notion is that...

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...

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a model that describes a two-stage process consisting of a production and an end-of-pipe abatement stage with the environmental efficiency being determined by the efficiency of...

We study the impact of the 1918 influenza pandemic on economic performance in Sweden. The pandemic was one of the severest and deadliest pandemics in human history, but it has hitherto received only scant attention in the economic literature - despite important implications for modern-day...

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...
