Research shows that exposure to local neighborhood violence is associated with students’ behavior and engagement in the classroom. Given the social nature of schooling, these symptoms not only affect individual students but have the potential to spill over and influence their classmates’ learning, as well. In this study, I use detailed administrative data from five complete cohorts of students in the Chicago Public Schools (2002 to 2010), crime data from the Chicago Police Department, and school-level surveys conducted by the University of Chicago Consortium on Chicago School Research to assess the strength of this peer effect. The estimated negative relationship between peer exposure to neighborhood violent crime and individual achievement is substantial and remains after adjusting for other peer characteristics and student fixed effects. Surveys suggest these results are related to trust, discipline, and safety concerns in cohorts with larger proportions of students from violent neighborhoods.

芝加哥的邻里暴力，同伴效应和学术成就

研究表明，暴露于当地社区暴力与学生的行为和参与课堂活动有关。考虑到学校教育的社会性质，这些症状不仅影响个别学生，而且还可能溢出并影响其同学的学习。在这项研究中，我使用了来自芝加哥公立学校（2002年至2010年）的五个完整学生队列的详细行政数据，芝加哥警察局的犯罪数据以及芝加哥大学联合会对芝加哥学校研究进行的学校级调查评估这种同伴效应的强度。同伴暴露于邻里暴力犯罪与个人成就之间的估计负相关关系是实质性的，并且在针对其他同伴特征和学生固定效应进行调整之后仍然存在。
