Changes in the Gender Wage Gap in Germany during a Period of Rising Wage Inequality 1999-2006: Was it Discrimination in the Returns to Human Capital?

Abstract

In this article I analyze the changes in the gender wage gap in the western region, eastern region and in reunified Germany during the period 1999 - 2006. I use data from the German Socio-Economic Panel and implement two alternative decomposition methodologies; the Juhn, Murphy and Pierce (1991) decomposition, and a methodology that totally differences the Oaxaca-Blinder (1973) decomposition, found in Smith and Welch (1989). I conclude that most of the increase in the gender wage gap occurred during a period of remarkably risingwage inequality and argue that both trends are caused simultaneously by the same set of factors. Furthermore, German women were, on average, treated favorably in the returns to their educational attainment, potential experience and tenure compared men, and that the increasing gender wage gap was mainly due to changes in the gender differentials in human capital endowments, particularly worker's potential experience, changes in the gender distribution across industries, company sizes and occupational positions and to changes in discrimination in the returns to job-specific training.
