This paper studies the impact of adult prosecution on recidivism and employment trajectories for adolescent, first-time felony defendants. We use extensive linked Criminal Justice Administrative Record System and socio-economic data from Wayne County, Michigan (Detroit).

We develop a novel econometric framework that combines standard regression discontinuity methods with predictive machine learning …
