The Effect of Fraternity Moratoriums on Alcohol Offenses and Sexual Assaults
利用2014-2019年间37所大学44次暂停兄弟会活动的政策变化，研究发现禁令使酒精犯罪减少26%，周末性侵犯报告减少29%，但无长期效果。
<h3>Abstract</h3> I exploit variation in timing from 44 temporary university-wide halts on all fraternity activity with alcohol (<i>moratoriums</i>) across 37 universities over 2014-2019. I construct a novel data set, merging incident-level crime logs from university police departments to provide the first causal estimates of the effect of moratoriums on reports of alcohol offenses and sexual assaults. In particular, I find robust evidence that moratoriums decrease alcohol offenses by 26%. Additionally, I find suggestive evidence that moratoriums decrease reports of sexual assault on the weekends by 29%. However, I do not find evidence of long-term changes once the moratorium is lifted.
