We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

Rising wage inequality in the U.S. and Britain (especially in the 1980s) and rising continental European unemployment (with rather stable wage inequality) have led to a popular view in the economics profession that these two phenomena are related to negative relative demand shocks against the...

This paper investigates whether and in what sense the west German wage structure has been ?rigid? in the 1990s. To test the hypothesis that a rigid wage structure has been responsible for rising low-skilled unemployment, I propose a methodology which makes less restrictive identifying...

We estimate the effects of income from various sources on charitable giving using administrative German income tax data. We demonstrate that charitable contributions are not uniformly affected by different income types. While business and capital income exhibit a positive effect, the remaining...

This paper studies whether the transition from a centrally planned to a market economy offers new perspectives for those who, in economic terms, were relatively deprived under the old regime. Previous empirical research on this question has been limited by the availability of representative...

In this study we assess the relationship between father and son earnings among (West) German Workers. To reduce the lifecycle and attenuation bias a novel sampling procedure is developed and applied to the German Socio-Economic Panel (SOEP) 1984-2006. Our preferred point estimate indicates that...

This paper investigates the changes in the German wage structure for fulltime working males from 1999 to 2006. Our analysis builds on the task-based approach introduced by Autor et al. (2003), as implemented by Spitz-Oener (2006) for Germany, and also accounts for job complexity. We perform a...

Using data from the German Socio Economic Panel (SOEP) for the years 1984 to 2007, this paper analyses the amount, the development and the explanations of wage mobility, as well as volatility in West Germany, measured by ranks in the wage distribution. Individual wage mobility decreased between...
