Gender quotas and company financial performance: A systematic review

Several countries have mandated sex quotas on corporate boards of directors. We systematically reviewed empirical studies that compared company profitability and financial performance before and after introducing legislated quotas. The search yielded 348 unique hits and nine studies were retained, including 20 effects. Four were null, 11 were negative, and five were positive, all of the latter for Italian and French companies. We conclude that quotas for women on corporate boards have mainly decreased company performance and that several moderating factors must be taken into account when assessing causal effects of quotas on company performance.
