New research busts the myth that female leaders are less corrupt
The long-held belief that putting women in charge will automatically clean up «dirty» politics may be more myth than reality. An analysis of two decades of local elections suggests that female leaders are no more or less likely to engage in graft than their male counterparts once they take the oath of office, according to a new study published by the U.S. National Bureau of Economic Research (NBER).

Researchers analyzed thousands of close, mixed-gender mayoral races in Brazil between 2000 and 2020 to determine if a leader’s gender influenced the level of government corruption. To avoid the pitfalls of using a single metric, the study utilized six different measures: machine-learning scores that predict corruption through budget patterns, official audit irregularities, and actual legal sanctions or fines for administrative misconduct.
The results were remarkably consistent. Across all twenty years and every category of measurement, electing a woman had no detectable impact on corruption levels. Having a female mayor did not reduce the probability of legal action, the suspension of political rights, or the amount of financial damage a municipality suffered due to embezzlement.
The incumbency trap
The findings challenge earlier research that suggested women were «cleaner» politicians. The authors of the new study discovered that those previous results likely suffered from a «confounding» factor: incumbency. In earlier electoral cycles, women who won close races were significantly less likely to be incumbents (serving their second term) than the men they defeated.
In the Brazilian system, mayors are limited to two consecutive terms. The study found that incumbency itself is a primary driver of corruption; second-term mayors, who face no immediate reelection pressure, are far more likely to engage in misconduct. When researchers compared female mayors to male mayors with the same level of experience, the gender gap in corruption completely disappeared.
Education and political equity
While their integrity levels matched, the study did find that female mayors in Brazil were significantly more educated than their male rivals, being nearly 17 percentage points more likely to have completed higher education. Despite this academic advantage, their governance style regarding corruption remained similar to that of men.
Ultimately, the researchers argue that the drive for female political representation should be rooted in democratic equity rather than the expectation that women will act as a unique «fix» for systemic corruption. The study underscores that corruption is driven by institutional factors — like term limits and political networks — rather than the gender of the person in the mayor’s office.
