We examined the impact of Raise the Age (RTA) in Massachusetts, which increased the maximum jurisdictional age for its juvenile court in late 2013. Using statewide re-arraignment data and a difference-in-differences research design comparing affected 17-year-olds to unaffected 18-year-olds, we find that RTA increased recidivism for affected 17-year-olds. The observed increases in recidivism were especially large for 17-year-olds without prior justice involvement. This result may stem from the more extensive use of pretrial supervision or the diminished deterrence of prosecution within the Massachusetts juvenile justice system.

估计缩小刑事司法系统对刑事累犯的影响

我们检查了马萨诸塞州提高年龄 (RTA) 的影响，该法案在 2013 年底提高了其少年法庭的最高司法管辖年龄。使用全州范围内的重新传讯数据和差异研究设计来比较受影响的 17 岁儿童对于未受影响的 18 岁青少年，我们发现 RTA 增加了受影响 17 岁青少年的累犯率。对于没有事先司法介入的 17 岁儿童来说，观察到的累犯增加尤其大。这一结果可能源于更广泛地使用审前监督或马萨诸塞州少年司法系统内对起诉的威慑力减弱。
