Breaking Bad: Mechanisms of Social Influence and the Path to Criminality in Juvenile Jails
研究少年管教所中同伴影响如何通过社会传染机制增加释放后的犯罪行为，发现接触来自不稳定家庭且攻击性强的同伴会提高犯罪率，对犯罪预防有参考价值。
Abstract I conduct a series of tests of peer influence in juvenile incarceration facilities motivated by three mechanisms: criminal skill transfer, the formation of new criminal networks, and the social contagion of crime-oriented noncognitive factors. Identifying peer influence off natural variation in small cohorts within the same facility, I find evidence consistent with social contagion: exposure to peers who come from unstable homes and have high levels of aggression leads to an increase in crime after release, as well as an increase in crime-oriented attitudes and behaviors. This effect persists despite controlling for the criminal experience and gang affiliation of the cohort, and is found in settings where youths are unlikely to interact after release.
