Can prisons move people into better jobs? A look at correctional vocational training programs and sectoral employment outcomes

Criminology, EarlyView.
Abstract Three‐quarters of US prisons offer vocational training programs, which aim to place trainees in middle‐skills jobs in specific occupational sectors post‐release. These middle‐skills jobs may more effectively reduce recidivism than the jobs that normally characterize the labor market experience of the formerly incarcerated, yet whether ...
