Gender Earnings Gap in German Firms
AbstractMost existing analyses on the gender wage gap (GWG) have neglected the establishment as a place where inequality between male and female employees arises and is maintained. The use of linked employee-employer data permits us to move beyond the individual and consider the importance of the workplace to explain gender pay differentials. That is, we first provide a comprehensive study on the effects of various firm characteristics and the institutional framework on the GWG in Germany. The innovation of our research is that we do not just compare average male and female wages (of specific groups of employees), but look at within-firm gender wage differentials. Our results indicate that the mean GWG within firms is smaller than the average overall GWG. Furthermore, we can show that firms with formalized co-determination (works council) and those covered by collective wage agreements are more likely to have smaller GWG. It is also interesting to note that the wage differential between men and women decreases with firm size and increases with the wage level.

Non-technical summaryMost studies analyze gender pay differentials by focusing primarily on differences in the wage-determining characteristics of men and women and how these characteristics are rewarded. The goal of our research is to move beyond the individual and consider the importance of the workplace to explain gender pay differentials. The innovation of our research approach is that we do not just compare average male and female wages (of specific groups of employees), but look at within-firm gender wage differentials. In the following study, we will focus on the impact of works council and the collective bargaining coverage.An attempt to explain the wage differences between men and women would not be comprehensive and convincing, if Becker's theory on discrimination were not considered at all. We hence propose alternative concepts to test the hypotheses derived from the discrimination model. The empirical analysis is based on the German LIAB data, a representative linked employer-employee panel including information on all employees of firms covered by the IAB establishment survey.To investigate the theoretical hypotheses regarding the effect of firm and institutional characteristics on wage i...
