Abstract
This paper investigates the effect of the size of the local labor market on skill mismatch. Using survey data for Germany, I find that workers in large cities are both less likely to be overqualified for their job and to work in a different field than the one for which they trained. Different empirical strategies are employed to account for the potential sorting of talented workers into more urbanized areas. Results on individuals who have never moved away from the place in which they grew up and fixed effects estimates obtaining identification through regional migrants suggest that sorting does not fully explain the existing differences in qualification mismatch across areas. This provides evidence of the existence of agglomeration economies through better matches. However, lower qualification mismatch in larger cities is found to explain at best a small part of the urban wage premium.
The sources of the urban wage premium by worker skills: Spatial sorting or agglomeration economies?
