Neither markets nor philanthropy alone are sufficient to help the world's poorest people. In this audio interview with host Sheela Sethuraman, Jacqueline Novogratz, founder of the Acumen Fund, describes how a combination of patient capital plus management support is making a difference in tackling poverty in Africa and Asia. Novogratz shares experiences and anecdotes from her recently published book, The Blue Sweater: Bridging the Gap Between Rich and Poor in an Interconnected World.
