Are firms with female owners or managers less corrupt than other firms? We test this question using firm-level data on corruption, ownership, and management. We find that women in positions of influence are associated with less corruption: female owners are associated with a lower incidence of bribery and report smaller levels of bribery. Moreover, corruption is seen as less of an obstacle in companies where women are represented in top management. By providing evidence that women are associated with lower levels of corruption in business our research contributes to the literature on development, gender equality, and corruption.
