The Effect of School and Neighborhood Peers on Achievement, Misbehavior, and Adult Crime
利用夏洛特-梅克伦堡县的学生队列数据，研究发现父母曾被逮捕的同伴比例每增加5个百分点，会使学业成就下降0.016个标准差，成年被捕率上升5%，且同伴效应主要源于学校互动。
This paper assesses the importance of school and neighborhood peers in shaping educational achievement, adolescent misbehavior, and adult crime. Using cohort variation within Charlotte-Mecklenburg County, we focus on the impact of peers whose parents have been arrested, which is strongly and independently predictive of worse outcomes. Results indicate that a 5 percentage point increase in school peers linked to parental arrest reduces educational achievement by 0.016 standard deviations and increases adult arrest rates by 5%. Additional evidence indicates that peer effects are primarily driven by interactions in schools rather than in neighborhoods.
