This paper contributes to a better understanding of the role of bargaining and discrimination in the gender wage gap in France and four other European countries using comprehensive linked employer-employee data. The role of bargaining and discrimination is analysed by focusing on systematic differences in wage-setting practices between men and women in the same firm through the estimation of gender-specific firm wage premia. The paper provides three key insights. First, bargaining and discrimination account for only a small part of the gender wage gap in France. Second, the component of the gender wage gap that can be attributed to bargaining and discrimination is higher in high-wage firms in all countries considered. Third, cross-country differences in the importance of bargaining and discrimination in the gender wage gap reflect both systematic differences in wage-setting practices within firms and imperfections in the product market that generate persistent rents.
