This paper analyzes the early research performance of PhD graduates in labor economics, addressing the following questions: Are there major productivity differences between graduates from American and European institutions? If so, how relevant is the quality of the training received (i.e. ranking of institution and supervisor) and the research environment in the subsequent job placement institution? ...

This essay provides a broad and in-depth account of the effects of the post-enlargement migration flows on the receiving as well as sending countries in three broader areas: labour markets, welfare systems, and growth and competitiveness.

In this paper I assert that the entrepreneurial spirit can also exist in salaried jobs. I study the determinants of wages and the labor market success of two kinds of entrepreneurial women in Germany - self-employed and salaried businesswomen - and investigate whether ethnicity is important in these challenging jobs. Employing data from the German Socioeconomic Panel I estimate selection adjusted ...

Specifically, we consider the minority experts' own perceptions about these issues, the veracities and repercussions of unfavorable attitudes of natives. Employing newly available data from the IZA Expert Opinion Survey 2007 we depict main trends ...

Our paper deals with modeling the effects of introducing a market-based tool for improving end-users' efficiency in an energy market which is already regulated through a cap-and-trade system for green house gas emissions and a quota system meant to improve competitiveness of energy produced using renewable resources. Our results show that the regulation of energy demand achieves its underlying objects ...

In this paper we develop a dynamic structural life-cycle model of labor supply behavior which fully accounts for the effects of income tax and transfers on labor supply incentives. Additionally, the model recognizes the demand side driven rationing risk that might prevent individuals from realizing their optimal labor supply state, resulting in involuntary unemployment. We use this framework to study ...

Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national distribution of skills and thereby equality in the receiving society. This paper suggests that skilled immigration ...

Der Anstoß wurde von der Leibniz-Gemeinschaft, der Dachgesellschaft der Institute, aufgenommen und in den regelmäßigen Evaluationsprozess eingebracht. Er gründet auf der zwingenden Erkenntnis, ...

This paper studies the determinants of naturalization among Turkish and ex-Yugoslav immigrants in Germany differentiating between actual and planned citizenship. Using the German Socio-Economic Panel, we measure the impact that integration and ethnicity indicators exert on the probability to naturalize beyond the standard individual and human capital characteristics. A robust finding is that German ...

This paper assesses the dynamics of treatment effects arising from variation in the duration of training. We use German administrative data that have the extraordinary feature that the amount of treatment varies continuously from 10 days to 395 days (i.e. 13 months). This feature allows us to estimate a continuous dose-response function that relates each value of the dose, i.e. days of training, to ...
