The performance of politicians: The effect of gender quotas

•Implemented policies are affected by the gender of the politicians.•The share of women in local governments positively affects fertility rate.•More women in local governments are positively related to a proxy for efficiency.•No difference in the internal migration rate to municipalities run by men or women.

This paper investigates whether the gender of elected politicians affects political outcomes at the municipal level. Relying on Italian administrative data from 1991 to 2009, we are able to instrument the gender of elected politicians using an institutional exogenous change: a gender quota in the candidacy list enforced only in a subsample of municipalities and for a short period of time. While the gender of politicians does not affect the general 'quality of life', proxied by the internal migration rate, it does increase significantly both the efficacy of policies targeting women and households, proxied by the fertility rate, and the efficiency of the municipal administration, proxied by the actual size of the administrative bodies. These results, which are robust to several specifications and checks, suggest that affirmative action enhancing gender equality in political representation may be beneficial not only in terms of social justice but also from a political outcome perspective.
