We evaluate electronic monitoring as an alternative to prison for non-violent offenses. Leveraging plausibly exogenous variation in sentencing outcomes generated by quasirandom assignment of judges, we find electronic monitoring reduces reoffending at both extensive and intensive margins. Compared with prison, electronic monitoring is estimated to reduce the probability of reoffending by 22 percentage points 5 years after sentencing and by 11 percentage points 10 years after sentencing, with the cumulative number of offenses reduced by 45 percent 10 years after sentencing. These results demonstrate that electronic monitoring can have sustained crime-reducing effects.

电子监控可以减少再犯罪吗？

我们评估电子监控作为非暴力犯罪监狱的替代方案。利用由准随机分配法官产生的量刑结果中看似合理的外生变化，我们发现电子监控减少了广泛和密集边缘的再犯罪。与监狱相比，预计电子监控在判刑后5年再犯概率降低22个百分点，判刑后10年再犯概率降低11个百分点，判刑10年后累计犯罪次数减少45%。这些结果表明，电子监控可以持续减少犯罪。
