Are women less corrupt in business? We revisit this question using firm-level data from the World Bank’s Enterprise Surveys, which measure firms’ experience of corruption and the gender of their owners and top managers. We find that women in positions of influence are associated with less corruption: female-owned businesses pay less in bribes and corruption is seen as less of an obstacle in companies where women are represented in top management. By providing evidence that women are, ethically at least, good for business our research contributes to the literature on development, gender equality, and corruption more generally.
