RT Journal Article SR Electronic T1 Tough on Young Offenders: Harmful or Helpful? JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 1017-9113R3 DO 10.3368/jhr.57.4.1017-9113R3 A1 Giulia Lotti YR 2020 UL http://jhr.uwpress.org/content/early/2020/04/03/jhr.57.4.1017-9113R3.abstract AB How harshly should society punish young lawbreakers? Through a fuzzy regression discontinuity design, I compare harsh and rehabilitative criminal incarceration practices. Young offenders sent to the more rehabilitative youth facilities become less likely to reoffend. On the contrary, offenders at the margin of the age cut-off and exposed to the harsher youth facilities are 27 percent more likely to recidivate in the eight years subsequent to their custody, and they are more likely to commit violent offences, thefts, and criminal damages. Keeping young offenders separate from their older peers in prison seems effective, but only in institutions not solely focused on punishment.
