One of the larger problems for government, is that taking risks is difficult. Risks are expensive, and can lead to a host of problems when those risks don't give desired results.

Here's where social innovation is taking a chance. In the UK you have pay for results programs, called pay for success here in the states. How do these programs work? Who takes on the economic risk? How do we measure success? Can pay for success and social impact bonds help solve some of the wicked problems?

Host Lisa Schweitzer talks with two of the co-authors of the new book Payment by Results and Social Impact Bonds, Gary Painter and Christopher Fox.

Read along with us - next month, Antigone! Let us know what you think of the book & our podcasts on Facebook or Twitter.
