Release, Detain, or Surveil? The Effect of Electronic Monitoring on Defendant Outcomes
研究审前电子监控（戴电子脚镣）相比释放或拘留对被告行为、案件结果和总成本的影响，发现电子监控虽比拘留省钱，但相比释放未能有效阻止高成本犯罪。
This paper studies the effect of pretrial electronic monitoring (EM) relative to both pretrial release and pretrial detention (jail). EM often involves a defendant wearing an electronic bracelet, which aims to reduce pretrial misconduct at a low cost. Using the quasi-random assignment of bond court judges, I estimate the effect of EM versus release and EM versus detention on pretrial misconduct, case outcomes, future recidivism, and aggregate total costs. Results indicate that EM reduces overall costs relative to detention. However, EM does not prevent enough high-cost crime to justify its use relative to release.
