It has recently been claimed that, contrary to popular perception, suitably chosen environmental regulation is often beneficial for the regulated firms because it induces cost-reducing innovations. I analyze to which extent this position is compatible with microeconomic analysis. It turns out...

This paper analyzes the equilibrium outcomes in a network industry under different vertical market structures. In this industry, an upstream monopolist operates a network used as an input to produce horizontally differentiated final products that are imperfect substitutes. Three potential...

We examine vertical backward integration in a reducedform model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to integrate...

This paper examines the spatial dimension of marginal willingness to pay (MWP) for reduction of nuclear risks through increased insurance coverage. The effect of distance from a nuclear power plant on individuals’ MWP is ambiguous. MWP is expected to decrease with distance because the risk of...

This paper investigates the relationship between income satisfaction of adult children and their relative economic status, using data from the German Socio-Economic Panel and income rank as an indicator of status. The results show that children appear to compare their actual economic status with...

This paper examines costs in the Swiss nursing home industry, an issue of concern to Swiss policy makers because of the explosion of elderly care costs and the aging of the population. The paper considers estimation of a translog cost function employing panel data for a sample of 36 nonprofit...

This article investigates power and size of some tests for exogeneity of a binary explanatory variable in count models by conducting extensive Monte Carlo simulations. The tests under consideration are Hausman contrast tests as well as univariate Wald tests, including a new test of notably easy...

By means of a very simple example, this note illustrates the appeal of using Bayesian rather than classical methods to produce inference on hidden states in models of Markovian regime switching.

In der Sozialversicherung gelten Risikoselektionen als unerwuenscht, weil sie die Gefahr mit sich bringen, dass der einheitliche Risikopool in der Sozialversicherung aufgespalten und die sozialpolitisch gewuenschten Umverteilungsstroeme zwischen den Versicherten reduziert werden. Der Beitrag...
