In a recent paper Edward Lazear proposed the jack-of-all-trades view of entrepreneurship. Based on a coherent model of the choice between self-employment and paid employment he shows that having a background in a large number of different roles increases the probability of becoming an...

Using a large recent representative sample of the German population this paper contributes to the entrepreneurship literature by empirically testing the hypothesis that young and small firms are hothouses for nascent entrepreneurs. The empirical estimation takes the rare events nature of...

This paper provides a descriptive analysis of the demand for high-skilled workers using a new firm data set, the IZA International Employer Survey 2000. Our results suggest that while workers from EU-countries are mainly complements to domestic high-skilled workers, workers from non-EU countries...

Based on a large employer-employee matched data set, the paper investigates the effects of variable enforcement of German dismissal protection legislation on the employment dynamics in small establishments. Specifically, using a difference-in-differences approach, we study the effect of changes...

In western industrialized countries men are on average more than twice as active in entrepreneurship as women. Based on data from a recent representative survey of the adult population in Germany this paper uses an empirical model for the decision to become selfemployed to test for differences...

18 studies using data from 20 highly developed, developing, and less developed countries document that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. The existence of these so-called exporter wage premia is one of the stylized facts...

An empirical analysis of various waves of the ALLBUS social survey shows that union density fell substantially in West Germany from 1980 to 2000. Such a negative trend can be observed for men and women and for different groups of the workforce. Repeated crosssectional analyses suggest that a...

An empirical analysis of various waves of the ALLBUS social survey shows that the level and the structure of unionization has become more and more similar in eastern and western Germany in the period 1992 to 2000. The originally high level of union density in eastern Germany has dropped below...

Using a German employer-employee matched panel data set this paper examines the effects of High Performance Workplace Systems (HPWSs) on labor productivity (defined as sales per worker) and labor efficiency (defined as the inverse of unit labor costs). The estimation results indicate that simple...

Research in wage differentials has a long tradition. Prominent reasons why people make more or less money in the labor market include personal characteristics of the employee (e.g., human capital or gender), job characteristics (working conditions demanding compensating wage differentials), and...
