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 paper examines effects of reference pricing for prescription drugs in German social health insurance based on econometric panel data methods. We analyze the effect on ex-factory prices. Moreover, we investigate whether manufacturers adapt prices of their products not subject to reference...

We assume that central banks can control inflation so that inflation rates reflect the preferences of the central bank council. The hypothesis to be tested is that these preferences depend on the central bankers' educational and/or professional background. In a panel data analysis for the euro...

In the German wastewater sector, innovations are often regarded to be the key to both more efficient service provision and reduction of environmental and health-related problems. However, it is unclear what factors foster these innovations. One possible candidate factor is increased competition...

Huge underinvestment increases the need for private borrowing in the German hospital sector, the access to which is partly determined by the probability of default (PD) of individual hospitals. Using ordinary least squares and quantile regression techniques this paper provides first empirical...

Any researcher would certainly agree with Hamermesh's (1993:34) intuition about separability that the ease of substitution between any two production factors should be unaffected by a third factor that is separable from the others. This paper emphasizes that such a notion of separability needs...

Even though European labor markets are characterized by high average unemployment, there is a shortage of high-skilled labor, leading many European economists to argue for an immigration policy directed at actively recruiting highly qualified workers from abroad. It has further been argued that...
