From John Stossel's blog: Americans give a lot to charitable causes--much more than people in other countries. Good for us. And now there are new ways to give: Social impact bonds combine philanthropy and the profit motive. Goldman Sachs will spend $9.6 million to try to reduce recidivism among jailed teenagers in NYC. The program is run by the Osborne Association--David Condliffe explains that only if they successfully reduce recidivism will Goldman get back its investment, plus a return. Many business schools now teach courses on charity. Melissa Berman from Rockefeller Philanthropy Advisors instructs students in Columbia's MBA program how to identify and support effective non-profits. Howard Husock of the Manhattan Institute explains how good charity ideas spread. Renee Riddle's organization, Stars & Stripes Honor Flight, honors World War II veterans by taking them to their memorial in Washington, D.C.
