This paper, joint with Julia Hoefer, has just been issued as Discussion Paper number 17147 by the Centre for Economic Policy Research.
Abstract:
This paper explores the role of social norms in influencing the incidence of sexual assault, and the contribution of alcohol to such events. We build a decision theoretic model where agents may use alcohol as a “disinhibitor” to undermine social norms discouraging consensual sexual encounters outside marriage. This makes non-consensual encounters more likely. Stronger norms against consensual sex might therefore increase the incidence of non-consensual sex. We test the theory on data from US college campuses, using the presence of Planned Parenthood clinics in the county as an indicator of norms more accepting of consensual sex. Controlling for other factors, colleges in counties with fewer clinics have more incidents of rape and sexual assault in which alcohol is implicated. Colleges affiliated to the National Collegiate Athletic Association also have more such incidents, suggesting that sporting institutions also act as facilitators of a culture of sexual aggression. We provide suggestive evidence from attitudinal surveys and from campus religious affiliation that disapproval of consensual sex may indeed be involved. We explore rival explanations such as reporting and selection biases.
This paper, joint with Marie Lalanne, has now been published in The Journal of Institutional Economics, and you can find the link here. It’s worth noting that the paper has been significantly revised since earlier circulated versions, and in particular contains new results on homophily (both men and women derive more benefit from same-gender connections, and men have more of these than women do). Please cite only this version and not the earlier versions.
We investigate the impact of professional networks on men’s and women’s earnings, using a dataset of European and North American executives. The size of an individual’s network of influential former colleagues has a large positive association with remuneration, with an elasticity of around 21%. However, controlling for unobserved heterogeneity using various fixed effects as well as a placebo technique, we find that the real causal impact of networks is barely positive for men and significantly lower for women. We provide suggestive evidence indicating that the apparent discrimination against women is due to two factors: first, both men and women are helped more by own-gender than other-gender connections, and men have more of these than women do. Second, a subset of employers we identify as ‘female friendly firms’ recruit more women but reward networks less than other firms.
