A recent RCT in Liberia evaluated by IPA found strong effects ten years post-intervention, suggesting long-lasting reductions in crime.
Presumably referencing this from Innovations for Poverty Action:
Men offered CBT and cash were much less likely to commit thefts and robberies. In the long run, those in the therapy-only group reported 61 percent fewer crimes compared to men in the comparison group, while those who participated in STYL reported a 57 percent decrease in crimes committed. Interpolating, this translates to roughly 338 fewer crimes per subject over 10 years—$1.50 per crime avoided, given the low program cost.
