The internet has become an important data source for the Social Sciences because these data are available without lags, can be regarded as involuntary surveys and hence have no observer effect, can be geo-labeled, are available for countries across the globe and can be viewed in continuous time...

Meijer, Rohwedder, and Wansbeek (MRW, Journal of Business & Economic Statistics, 2012) develop methods for prediction of a single earnings figure per worker from mixture factor models fitted using earnings data from multiple linked data sources. MRW apply their method using parameter estimates...

This paper proposes a new approach for analyzing the relationship between macroeconomic factors and the income distribution. The conventional method of analysis is regression of summary inequality indices on variables such as the unemployment and inflation rates. Building on the lessons from...

The macro evidence of increased adjustment pressure since the early seventies suggests that job mobility should have increased. Hence, retrospective and spell data from the German Socio-Economic Panel are combined in order to test the hypothesis that job stability for German workers declined...

Using a stochastic frontier approach this paper evaluates the effects of substantial changes in the teaching material on students learning efficiency. The results indicate that the main effects of the re-organization on the learning efficiency was a decreasing importance of students' attendance...

One cornerstone of current attempts to reform the German public health care system by introducing private insurance schemes is the assumption that economic incentives play an important role in individual decision-making about using medical help.

Using standard as well as recently developed univariate and bivariate count data models, this paper analyzes the determinants of workplace accidents using a firm data set for Germany. Given the tight system of public workplace safety regulation, introduced partly as early as in 1869, and the...

Sharing the available stock of work more fairly is a popular concern in the public policy debate. One policy proposal is to reduce overtime work in order to allow the employment of more people. This paper suggests that such a concept faces major problems. Using Germany as a case study, it is...

This paper studies occupational mobility of ethnic German migrants who have entered Germany since 1984. The empirical analysis suggests significant differences in the probability of downward occupational mobility by gender, immigration status, and schooling levels. In general, migrants with...

We examine the determinants of low income transitions using first-order Markov models that control for initial conditions effects (those found to be poor in the base year may be a nonrandom sample) and for attrition (panel retention may also be non-random). Our econometric model is a form of...
