I think crime prevention and reducing recidivism rates are clearly the places to start. That's not narrowing it down all that much. The social impact bond or the social finance tool is applicable in that relatively narrow range of interventions that focus on prevention.
We're not talking about an overhaul of core service delivery. We're talking about the places where governments intervene to prevent negative outcomes. These are the places these tools could be applicable.
I think one of the ways we could make this tool available in the tool box is through an outcomes payment fund. I don't know if you're familiar with the Department for Work and Pensions innovation fund in the United Kingdom. Essentially they established the priorities they had as a government and the prices they were willing to pay for these outcomes, what these problems were currently costing them, and what they were willing to pay for them. They had a fund set up that would pay on the basis of those outcomes being achieved, and they let the market respond with solutions.
I think that's one really interesting way to find a good match between the tool and the problem.
