A must-read book for social entrepreneurs combating global poverty. . . .

This important, carefully researched, and compelling book presents the facts about the poor and their relationship to finance."--Tim Harford, author of "The Undercover Economist" and "The Logic of Life"This is an important, boots-on-the-ground look at how microfinance functions in the developing world.
