Using administrative data for West Germany, this paper investigates whether part of the urban wage premium stems from fierce competition in thick labour markets. We first establish that employers possess less wage-setting power in denser markets. Local differences in wage-setting power predict...

This paper investigates women's and men's labor supply to the firm within a structural approach based on a dynamic model of new monopsony. Using methods of survival analysis and a linked employer-employee dataset for Germany, we find that labor supply elasticities are small (0.9?2.4) and that...

This paper presents an alternative explanation of the gender pay gap resting on a simple Hotelling-style dyopsony model of the labor market. Since there are only two employers equally productive women and men have to commute and face travel cost to do so. We assume that a fraction of the women...

This paper investigates the behaviour of employers' monopsony power and workers' wages over the business cycle. Using German administrative linked employer employee data for the years 1985-2010 and an estimation framework based on duration models, we construct a time series of the firm-level...

This paper investigates immigrants' and natives' labour supply to the firm within a semi-structural approach based on a dynamic monopsony framework. Applying duration models to a large administrative employer-employee data set for Germany, we find that once accounting for unobserved worker...

In West Germany, the average size of establishments declined during the 1990s and started to increase again in the late 2000s, while the employer size wage premium followed the opposite trajectory. In this paper, we show that these two developments are interrelated. More precisely, our results...
