Research on the program conducted by the University of Chicago Crime Lab and just published in the journal Science suggests that these summer jobs have actually had such an effect: Students who were randomly assigned to participate in the program had 43 percent fewer violent-crime arrests over 16 months, compared to students in a control group.
That number is striking for a couple of reasons: It implies that a relatively short (and inexpensive) intervention like an eight-week summer jobs program can have a lasting effect on teenage behavior. And it lends empirical support to a popular refrain by advocates: “Nothing stops a bullet like a job.”
Researcher Sara Heller conducted a randomized control trial with the program, in partnership with the city. The study included 1,634 teens at 13 high schools. They were, on average, C students, almost all of them eligible for free or reduced-price lunch. Twenty percent of the group had already been arrested, and 20 percent had already been victims of crime.
