What if someone told you that you could dramatically reduce the crime rate without resorting to coercive policing or incarceration? In fact, what if they said you could avert a serious crime — a robbery, say, or maybe even a murder — just by shelling out $1.50?
That’s such an incredibly good deal that it sounds too good to be true. But it’s been borne out by the research of Chris Blattman, Margaret Sheridan, Julian Jamison, and Sebastian Chaskel. Their new study provides experimental evidence that offering at-risk men a few weeks of behavioral therapy plus a bit of cash reduces the future risk of crime and violence, even 10 years after the intervention.
