In this paper, we provide a comprehensive multivariate cointegration analysis of three parts of the steam coal value chain - export, transport and import prices. The analysis is based on a rich dataset of international coal prices; in particular, we combine data on steam coal prices with freight rates, covering the period December 2001 until August 2009 at weekly frequency. We then test whether...

In 1999, in Germany, the statutory sick pay level was increased from 80 to 100 percent of foregone earnings for sickness episodes of up to six weeks. We show that this reform has led to an increase in average absence days of about 10 percent or one additional day per employee, per year. The estimates are based on SOEP survey data and parametric, nonparametric, and combined matching-regression...

Taking advantage of the panel structure of the data, the impact of intermarriage on labor market productivity as measured by earnings is examined. Contrarily to previous studies which rely on instrumental variable techniques, selection issues are addressed within a fixed effects framework. The model accounts for short and long term effects as well as general differences between those who...

This paper studies the cost structure of water distribution utilities in Germany. Stochastic cost frontier models are applied to an unbalanced panel of 371 observations of 72 companies in the period from 1998 to 2007. The results suggest that some utilities could reduce their costs by more than 20%. Water losses and elevation differences in a service area turn out to be significant cost drivers....
