Can Crime Be Deterred at Low Cost? Evidence From a Randomized Experiment in New York
研究了一项低成本信息干预对高风险假释人员再犯罪的影响，发现干预未显著减少逮捕或产生社区溢出效应，但降低了15%的假释违规。
ABSTRACT Can crime be deterred at low cost? We report the results of a randomized experiment of a messaging intervention designed to deter offending among individuals under parole supervision with a prior violent felony conviction or firearm arrest. The intervention consisted of a group meeting in which high‐risk paroled individuals were notified of the sanction they would face upon reoffending while being offered community resources to support re‐integration into the community. The program did not lead to a notable reduction in future arrests or create community spillover effects but did reduce parole violations by 15%. Potential mechanisms and implications for similar programs are discussed.
