  1. \(\Delta = \hat{\alpha }_1^{base}\) is the coefficient estimate of Female X Year from the base and \(\hat{\alpha }_1^{full}\) is the corresponding coefficient estimate from the full regression. Female X Year is an interaction between the female and 2020-year dummy. Dummy variables if not specified differently. Secondary education (Realschule), Old (50–67) years and large firm (more than 1,999 employees) used as reference categories, respectively. Log hourly gross wage in 2015-prices. Federal state as well as occupation (ISCO 88, 1 digit) and industry (NACE, level 1) dummies included. Interaction of controls with female and year dummy, respectively, included in the full regression. Robust standard errors in parentheses. \(*** p<0.01, ** p<0.05, * p<0.1\). SOEP sample weights used.
