There have long been programs where individuals from high risk groups have been rewarded with either cash or other incentives to do things that some might simply call behaving. Examples would include paying people to stay in school, to come to health clinic appointments for themselves or their children, to read books. At times the money came from government others from NGOs. The results have been mixed.
Your employer may have given you a bonus because you did your job well, showed up on time always, were available for overtime. That is being paid for behaving. You may have paid your children, or grandchildren for getting good grades.
Money is the carrot, incarceration is the stick. The carrot is much cheaper than the stick. Society is going to pay one way or the other. If the program works, and it seems to have elsewhere, then staying out of trouble may become a pattern for some or many of these at-risk people.

This is exactly what the Alaska Fund does, distributes cash to every citizen of Alaska to do with as they please.
