Employer concentration and worker mobility in France
A growing literature has documented that employer concentration is associated with lower wages but it has abstracted from job-to-job mobility. This is problematic because worker mobility is an important source of wage growth and thus these models do not give workers a chance to "flight back" against employer concentration. In this paper I propose a model of the labor market calibrated to employer-employee data from France and use it to quantify the effects of firm market power on wages and study the effect of non-compete agreements between workers and firms.
