重新审视家庭暴力暴露同伴的同伴效应
Reconsidering Peer Effects from Schoolmates Exposed to Violence at Home
摘要
Abstract Prior research suggests that students exposed to domestic violence impose substantial negative externalities on peers’ learning and labor market outcomes. We test whether these findings generalize using nine-years of student data from a large urban school district linked to geocoded police records of at-home violence. In contrast to prior work, we find negligible peer effects. Adding one exposed peer to a classroom of 20 students reduces English and math scores by a statistically insignificant 0.006 standard deviations and increases disciplinary incidents by 3.2%. We reject achievement reductions greater than 0.017 standard deviations and disciplinary increases larger than 8.3%.
中文摘要
先前研究表明，遭受家庭暴力的学生会对同伴的学习及劳动力市场结果产生显著的负面外部效应。我们利用一个大城市学区九年的学生数据，结合地理编码的警方家庭暴力记录，检验这些发现是否具有普遍性。与先前研究相反，我们发现同伴效应微乎其微。在一个20名学生的班级中增加一名受暴露同伴，会使英语和数学成绩下降0.006个标准差，但统计上不显著，同时纪律事件增加3.2%。我们排除了成绩下降超过0.017个标准差及纪律事件增加超过8.3%的可能性。
