I think there is certainly evidence on the basis of public-private partnerships, not the social bond. In terms of the kinds of projects that people like to invest in, there's been quite a bit of work done on the use of these kinds of approaches in Latin America and the Caribbean. Certainly in Brazil, what you would find is that many private investors like to put money into young kids who haven't got into trouble, into communities, and into the police. They don't want to touch kids coming out of institutions, and they don't want to touch adult prisoners. So it's a bit like the cuddly animal that sells the cellphone. There are certain things that people are more likely to want to invest in than others.
The examples that I can see that are being funded in Massachusetts and in the States and in the U.K. are quite traditional projects. They're doing the kinds of things people have done forever: supporting kids, giving them resources, supporting people coming out of prison.
