I develop an intra-firm theory of group design and teamwork in the presence of peer effects. The purpose is to understand the interlinkages between intra-firm group formation and the extent of wage dispersion within the firm. Given a set of heterogeneous workers, the manager faces the challenge...

Women still earn less than men on average in Germany. This applies to management positions even more: between 2010 and 2016, there was an average gender pay gap of 30 percent in gross hourly earnings. If gender-specific differences in relevant wage determinants are excluded, a pay gap of 11...

Wage Dispersion and Efficiency. It is often assumed that markets generate efficient allocations, but these are not necessarily fair. The widening of wage differentials that is currently observed is interpreted in this manner: Skill-biased technological progress increases demand for skilled work...

We use data on twins matched to register-based information on earnings to examine the long-standing puzzle of non-existent compensating wage differentials. The use of twin data allows us to remove otherwise unobserved productivity differences that were the prominent reason for estimation bias in...

We develop a search model of informal labor markets with worker and firm heterogeneity, intra-firm bargaining with imperfect substitutability across types of workers, and a comprehensive set of labor regulations, including minimum wage. Stylized facts associated with the informal sector, such as...

In this paper we develop a model capturing key features of the Roy model, a search model, compensating differentials, and human capital accumulation on-the-job. We establish which features of the model can be non-parametrically identified and which cannot. We estimate the model and use it to...

The large inflow of less-educated immigrants that the United States has received in recent decades can worsen or improve U.S. natives' labor market opportunities. Although there is a general consensus that low-skilled immigrants tend to hold "worse" jobs than U.S. natives, the impact of...
