The question of whether two drugs - namely alcohol and tobacco - are used as complements or substitutes is of crucial interest if side-effects of anti-drug policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and...

This article analyses value changes of German stock market companies in response to movements of the US dollar. The approach followed in this work extends the standard means of measuring exchange rate exposure in several ways (e.g. by using multi-factor modelling instead of augmented CAPM,...

Our study is based on the traditional Becker-Ehrlich deterrence model, but we analyse the model in the face of currently discussed factors of crime like demographic changes, youth-unemployment and income inequality. We use a panel of the German Laender (states) that allows us to exploit...

The rising trends both in drug addiction and crime rates are of major public concern in Germany. Surprisingly, the economic theory of crime seems to ignore the drugs?crime nexus, whereas the criminological literature considers illicit drug use a main reason of criminal activities. This paper...

This paper compares technologies across space and time on the basis of factual and counterfactual substitution elasticities and argues that differences in estimated substitution elasticities should be decomposed into two counterfactual components. While the first component is designed to...

Die Studie untersucht den Zusammenhang zwischen Dollar- und Aktienkursen. Da für sehr lange Zeiträume nur schwache bivariate Zusammenhänge feststellbar sind, wird die (begrenzte) Informationsmenge der Marktteilnehmer durch abschnittsweise Teilmengen des Untersuchungszeitraums (1974 - 1995)...

We estimate the Dollar exposure of German DAX corporations. Our results are based on a new time-variant, APT-based and panel econometric extension of the exchange-rate exposure model in the tradition of Adler and Dumas (1984) and Jorion (1990). Our stock market data consist of 28 performance...
