I think because the model is so new, there are a lot of ideas floating around, whether within governments or in the social sector generally.
Ideas are great, but I think at some point we have to get to the point where we can prove or disprove the model's utility. For us, we're going through these feasibility studies and if we get to the point where the feasibility study shows that it's not going to work, we're actually not going to be that disappointed about it, because we're going to be able to share with the sector that this model does not work in issue area X. So we can shorten that list or increase that list depending on that type of study.
Sarah spoke to the government side of things, but we have to remember there is another stakeholder in a social impact bond, and that is the investor. It's of importance or it's interesting to them to figure out where they would like to invest their money. If they're not interested in a specific issue area, then it's going to be very difficult for anybody to raise money in that area.
Something that is one of the benefits is also a limiting function of the social impact bond, and that is that there has to be agreement from all three sides of the equation.
