Where women make a difference. gender quotas and firms’ performance in three european countries

The authors study the effect of corporate board gender quotas on firm performance in France, Italy, and Spain. The identification strategy exploits the exogenous variation in mandated gender quotas within country and over time and uses a counterfactual methodology. Using firm-level accounting data and a difference-in-difference estimator, the authors find that gender quotas had either a negative or an insignificant effect on firm performance in the countries considered with the exception of Italy, where they find a positive impact on productivity. The authors then focus on Italy. Using a novel data set containing detailed information on board members’ characteristics, they offer possible explanations for the positive effect of gender quotas. The results provide an important contribution to the policy debate about the optimal design of legislation on corporate gender quotas.
