I have a little less patience, given where the social finance sector is. That's not to say that there aren't good proposals around social impact bonds, but they're not really bonds. The framework of thinking about them in the way of bonds is, I think, confusing. While they may scale one operation, how translatable they are to another is unclear to me.
I think pay-for-performance is a good concept, but at this point in the development of social finance, and the role the government can play around the role of social finance, social impact bonds can be somewhat distracting.
I'll say that Vancity is looking at one now in partnership with MaRS and federal health authorities.
