Salary and reservation wage gender gaps in Polish academia

By using unique web-survey data, this paper assesses the gender wage gap in Polish academia. We conduct a detailed study of the gender gap considering monthly salaries and reservation wages. The study involves regression analysis, Oaxaca-Blinder decomposition of mean wage differentials and decomposition of differences in distributions using quintile regression. The results from the Oaxaca-Blinder wage decomposition imply that differences in total salary are mostly due to academic rank. For reservation wages there is evidence of a mean residual gap of 10%. In addition, both differences in raw salary and the reservation wage between females and males are more pronounced at the top of the distribution.
