The Best-Case Scenario: When Quotas Deliver
Gender quotas can produce measurable improvements in public service delivery and governance, especially in contexts with low corruption. A study of African countries found that implementing gender quota laws—specifically reserved parliamentary seats for women—was associated with a 4.71 percentage point increase in the likelihood of people accessing safely managed drinking water [5]. This effect was even stronger when quotas mandated reserving more than 20% of seats for women, leading to a 12.25 percentage point increase [5]. The benefits were largest for the most vulnerable groups: poorer households, female-headed households, and those in rural areas [5].
In Mumbai's city council, randomly imposed electoral quotas for women led to faster processing of citizen complaints and higher perceived quality of local public goods [3]. Quota members focused more on public goods distribution, while non-quota members prioritized individual perks and identity issues [3]. Similarly, in India's local governments, reservation quotas increased the provision of public goods aligned with female voters' preferences and improved men's perceptions of women as leaders [4].
Quotas can also shift the substance of lawmaking. In the French Parliament, female legislators were most active on women's issues, while men focused on military issues, suggesting quotas lead to a greater prevalence of women's issues in parliamentary debate [7]. Additionally, quotas in European Parliament elections were associated with higher overall educational attainment in parliamentary delegations, increasing the number of educated women and also raising the education level of remaining men [9].
The Catch: When Corruption Undermines Quotas
The most important caveat is that quotas only improve governance when corruption is low. A global study of 182 countries from 1900 to 2014 found that women's representation promotes human development only under low corruption; under high corruption, women's inclusion was associated with worsened development outcomes [1]. The reason is that in corrupt environments, women representatives may be recruited from the same corrupt networks as male patrons, serving as 'window-dressing' to legitimize rule while male patrons continue to dominate policy decisions [1].
This finding explains why quotas sometimes fail to deliver. In Albania, after gender quotas were implemented in 2015, women councilors were more likely than men to challenge practices concerning transparency, but the greatest gender gap was observed in councils where quotas had most disrupted male dominance numerically [8]. This suggests that quotas can trigger resistance or co-optation in contexts where male dominance is deeply entrenched.
Even in successful cases, the effects are not uniform. A study of Spanish municipal councils found that while quotas increased female representation, they had no significant effect on the overall education levels of elected councilors on average [2]. However, quotas increased average education in municipalities with initially lower education levels, but decreased it in those with higher pre-quota education levels [2]. This shows that quotas can have divergent effects depending on local conditions.
The Broader Impact: Beyond Policy Outcomes
Quotas also affect political engagement and perceptions. In Western Europe, the introduction of gender quotas reduced the gender gap in political knowledge among younger individuals, though effects were insignificant for older citizens [6]. This suggests quotas serve as an attention-raising event that enhances political awareness, especially for younger women [6].
In Nepal, quotas transformed women's lives beyond politics. Women who entered politics through quotas gained power and prestige that improved their position in both their families and society, shifting the discourse from viewing women's participation as an exception to an entitlement [10]. This symbolic effect—changing perceptions of women as leaders—is a key benefit of quotas, even when immediate governance improvements are modest.
However, the evidence is clear that quotas are not a silver bullet. They work best in low-corruption environments with strong institutions, and their effects vary by context, policy area, and the specific design of the quota (e.g., reserved seats vs. party quotas). Policymakers should pair quotas with anti-corruption measures and institutional reforms to maximize their potential.
