Against a background of custodial overcrowding, building obsolescence and a high recidivism rate, the Ministry of Justice questioned a rehabilitation investment of more than 100 million euros in the Bordeaux Gradignan prison.
CITIZING was sollicited by the Comissariat Général à l'Investissment (Commissariat-General for Investment) to give a second, expert opinion on the socio-economic impact of the project. The initial evaluation having identified the financial costs of the rehabilitation, CITIZING developed the socio-economic benefits model. The impacts measured related to decreased recidivism, litigation costs, CO2 emissions, suicides and increased well-being at work.
Principal results: the rehabilitation of the prison creates more collective value than it destroys, conditional on a constant number of detainees ; the investment is thus collectively desirable.
