I'm stuck on this one. We have a long history in the States of philanthropically funded, relatively small-scale programs that have looked very good and have been evaluated and have shown some positive effects. But government, for the most part, has not taken them up because of the fear that doing it at scale would not be successful. What this does is mitigate some of those risks associated with doing it at scale.
It's a legitimate risk to worry about, because we don't know that it's going to be as successful, when you have done something on a small scale and you expand it to a larger scale,.
Here, the upfront costs are covered by the investor. The government pays back only if it's successful. Then if it's successful, the government, and not the investor, reaps the rewards in the future of having a program that's been evaluated and that's been shown to work.
