Why do women earn more than men in some regions?
Abstract
"This paper provides first-time evidence on the magnitude and determinants of regional differences in the gender pay gap (GPG) in Germany. Using a comprehensive data set of all full-time employees, we conduct Oaxaca-Blinder decompositions for Germany and its regions to explain the regional variation of the GPG with theory-based individual, job-related and regional characteristics. Our results provide several novel insights into the regional dimension of the GPG. First, men's wages are more strongly correlated with the regional GPG than those of women, indicating that their wages drive the regional variation in the GPG much more than the wages of women. Second, the decomposition results reveal pronounced differences in the impact of the individual and job-related characteristics between the regions. Whereas job-related characteristics are important in regions with a high GPG, individual characteristics rather come into play in regions with a low or negative GPG. The results underscore the role played by the establishment composition in a region and the kind of jobs provided for the regional GPG. Women earn more than men in regions with a weak local economic structure and the absence of large firms providing well-paid manufacturing jobs. In regions with a high GPG, in contrast, men usually benefit from such jobs. The third result relates to the validity of the theoretical determinants of the GPG in regional respect. In contrast to the clear-cut decomposition results at the national level, at the regional level their validity mainly applies to specific subsets of regions. We conclude that analyses at the national level come too short in precisely explaining the regional variation of the GPG." (Author's abstract, IAB-Doku) ((en))
