Ich untersuche die Beschäftigungsverläufe von deutschen Ausbildungsabsolventen, wie sich frühe Beschäftigungsstabilität auf spätere Löhne auswirkt, und wie sich dieser Zusammenhang seit den späten 1970er Jahren verändert hat. In den Daten zeigt sich seit den späten 1980er Jahren ein...

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...

Bislang liegen kaum Untersuchungen zum Einfluss von Langzeit- und Kurzzeitarbeitslosigkeit auf die Erwerbsbeteiligung vor. Deshalb haben wir mit Daten für Deutschland, getrennt nach Alter und Geschlecht, die Arbeitslosenrate nach Kurz- und Langzeitarbeitslosigkeit getrennt und untersucht,...

From 1992 to 2005, part-time employment in Western Germany has grown by 82 percent, whereas full-time employment has shrunk by 14 percent. Behind these general figures there is substantial variation of employment schemes across industries. Beside this, the share of the service industries in...

This study investigates how the effects of low-wage employment and non-employment on wage prospects vary depending on qualification. We apply dynamic multinomial logit models with random effects and include interactions of the lagged labor market state with qualification to estimate...

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...

This paper examines empirically the relationship between innovation and market structure within a simultaneous framework at the industry level of aggregation. We use a model in which R&D affects both, demand and cost conditions. An optimization process leads to optimal industry R&D expenditure...

Using data from 49 European regions covering 2005-2012, this paper finds that the estimated effect of cohort size on employment and unemployment outcomes is very sensitive to the age range of the sample. We argue that this is because the identification strategy commonly used in this literature...

Analyzing gender gaps of unemployed job-seekers, this study uniquely complements the broad literature focussing predominantly on gender gaps of employed workers. I consider a broad range of labor market outcomes, and disentangle the factors driving the labor market gaps of unemployed men and...

Among health care systems with both public and private elements (such as in the US and Germany), an important question is whether the type of health insurance exerts an impact on workers' careers. We exploit the unique German case of a two-tier health care system to analyze whether opting out of...
