FACULTÉ & RECHERCHE

Using a diff-in-diff approach, we compare the impact on board and directors’ characteristics of mandatory vs advisory regulations on gender quotas in corporate boards. We focus on the experience of three European countries: France and Italy (mandatory regime) vs UK (advisory regime). Our results show that while the percentage of Women on Boards (WoB) generally increases after the introduction of the regulation, this effect is stronger in mandatory regimes. We also find that the quality of the board, measured by several indicators such as size, busyness, qualifications, independence, generally improves more in mandatory regimes. Finally, we also document that gender quotas have had no effect on the likelihood of appointing female executives and board chairwomen in either regime
