When one firm's strategy affects other firms' value, optimal executive incentives depend on whether shareholders have interests in only one or in multiple firms. Performance-sensitive contracts induce managerial effort to reduce costs, and lower costs induce higher output. Hence, greater...

We investigate the effects of two reforms of temporary employment using panel data on Italian firms. We exploit variation in their implementation across regions and sectors for identification. We find that the reform of apprenticeship contracts increased job turnover and induced the substitution...

The large regional variation in minimum wage levels in the period 2002-08 in China implies that Chinese manufacturing firms experienced competitive shocks as a function of firm location and their low-wage employment share. We find that minimum wage hikes accelerate the input substitution from...

Immigrants in many countries have lower employment rates and lower earnings than natives. We study whether a more liberal access to citizenship improves the economic integration of immigrants. Our analysis relies on two major immigration reforms in Germany, a country with a weak record of...

This doctoral thesis analyses the impact of education and other determinants on labour market outcomes using microeconometric methods. Chapter 1 serves as an introduction. Chapter 2 uses a randomised field experiment among German human resource managers to evaluate which skill signals such as...

The aim of this paper is to measure the returns to human capital. We use a unique data set consisting of matched employer-employee information. Data on individuals’ human capital include a set of 26 tasks that capture the utilization of workers’ skills in a very detailed way. Thus, we can...

It is well-established that human capital contributes to unequal levels of earnings mobility. Individuals with higher levels of human capital, typically measured through education, earn more on average and are privy to greater levels of upward change over time. Nevertheless, other factors may...

An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit...

This paper analyses the effects of education signals for Ethnic Germans and Germans without a migration background ('Native Germans'). We base our analysis on a sorting model with productivity enhancing effects of education. We compare whether the signalling value differs between the migrants...

We extract estimation results on the Mincer earnings function from four earlier studies and add new results from a recent dataset. We analyse differences related to differences in earnings concepts, in sampling frame and differences among studies that cannot be explained. Jointly, the studies...
