School Time and Crime: Incapacitation Effects in Brazil

Orientador(a): Claudio Ferraz

Juvenile crime imposes non-trivial costs to societies, which have made its determinants and deterrents increasingly subject of study by economists. School-based interventions are often proposed in order to mitigate the rise in criminal careers and the perpetuation of violence. However, the directions and channels through which schooling may affect crime vary. This paper studies one of them - namely the incapacitation effects - exploiting a federal program that extended school hours in Brazilian public schools. Using quasiexperimental variation in the probability of receiving the program and georeferenced crime data from the state of São Paulo, it is possible to estimate the causal effect of the program on criminal activity in the surroundings of the schools. Results suggest incapacitation does prevent juveniles from engaging in less offensive crimes, with stronger evidence for drug-related crimes and for schools with poorer students.
