DP20236 Women Behind Bars: Do Single-Gender Prisons Reduce Recidivism?
In 143 countries incarcerated women serve their sentence in a typically small separate section within prisons that mainly house male inmates, while 79 countries have prisons exclusively dedicated to women. Exploiting data from Italy, where both prison types coexist, and a quasi-random institutional assignment rule, we find that women-only prisons lower three-year recidivism by up to 16 percentage points. We use policy-relevant treatment effects to identify the optimal location of an additional women-only prison. As for the mechanisms, a driver is the presence of a large enough number of women for a given facility.
