This paper analyses the relationship between wage inequality and labour market development. Relevant economic theories are ambiguous, just as public debates. We measure the effects of wage inequality, skill-biased and skill-neutral technology on hours worked, productivity and wages in a novel...

Does interacting product and labor market regulation alter the impact of immigration on wages of competing native workers? Focusing on the large, sudden and unanticipated wave of migration from East to West Germany after German reunification and allowing for endogenous immigration, we compare...

We consider Roy's economies with perfectly competitive labor markets and asymmetric information. Firms choose their investments in physical capital before observing the characteristics of the labor markets they will face. We provide conditions under which equilibrium allocations are constrained...

We consider an economy where production may use labor of two different skill levels. Workers are heterogeneous and, by investing in education, self-select into one of the two skills. Ex-ante, when firms choose their investments in physical capital, they do not know the level of human capital...

We examine the effects of endogenous offshoring on cost-efficiency, wages and unemployment in a task-assignment model with skill heterogeneity. Exact conditions for the following insights are derived. The distributional effect of offshoring (high-) low-skill-intensive tasks is similar to...

Dass Arbeitsmarkt-Pooling einer der Vorteile von Ballungsräumen ist, ist zwar empirisch belegt, theoretisch jedoch nur gering fundiert. Der Beitrag stellt ein Modell der Humankapitalbildung in einem imperfekten kompetitiven gepoolten Arbeitsmarkt mit heterogenen Arbeitskräften und Unternehmen...

Proficiency in the host country's language is an important factor for a successful labor market integration of immigrants. In this study we analyze the effects of a language training program for professional purposes on the employment opportunities of the participants. We apply an instrumental...

In a structural macroeconometric analysis based on comprehensive micro data, we examine the role of skill-biased technical change for the flattening of productivity growth and effects on hours worked. The results show that more than 60 percent of the slowdown in productivity growth in Germany...

Demographic change implies an increasing demand for elderly care and a lower labor force potential at the same time. Training unemployed workers in care occupations might mitigate this problem. This study analyzes the effectiveness of subsidized training in elderly care professions for the...

The transition towards a greener, less carbon-intensive economy leads to a growing demand for green products, services and business processes. In theory, this trend should lead to a greening of jobs, i.e. to an increasing share of environmentally friendly requirements within occupations...
