ABSTRACT We analyse the impact of longer incarceration terms in juvenile correctional facilities on short-term criminal recidivism. We exploit a legal modification in Uruguay that significantly increased the sentence length for violent crimes. We find that more time in custody, even under very harsh conditions, is associated with reductions in reoffending. Although in line with much of the related economic literature, our findings question recent empirical findings suggesting that juvenile incarceration increases criminal recidivism.

释放后的少年监禁和犯罪：《哈氏法》的短期证据

摘要我们分析了少年教养所中更长的监禁期对短期犯罪累犯的影响。我们利用乌拉圭的法律修改，该修改大大增加了暴力犯罪的刑期。我们发现，即使在非常恶劣的条件下，更多的羁押时间也与减少再犯有关。尽管与许多相关的经济文献一致，但我们的发现对最近的经验发现提出了质疑，这些发现表明，少年监禁会增加犯罪再犯。
