Ever since a 2001 World Bank report, many policymakers have come to accept a gender-based approach to corruption control, which posits that women in government reduce corruption because females are more ethical than males. An alternative explanation asserting the spuriousness of the gender-corruption link suggests that both gender equality and lower corruption result from a functioning liberal democracy. In this study, eight hypotheses are formulated and tested with longitudinal data for 204 countries. Findings demonstrate that neither the level of women in government nor a change in it has any impact on the prevalence and/or short-term trend of corruption. But both the strength of liberal institutions and an increase in this strength predict the prevalence and trend of corruption.
