Market-based development strategies designed to help the world's poor receive significant support from advocates, academics, governments, and the media, yet frequently the perceived success of these programs rests on carefully selected examples and one-sided, enthusiastic accounts. In practice, these approaches are often poorly defined and executed, with little balanced, comparative analysis of their true strengths and weaknesses. This book is the first to assess emerging market-based social change approaches comparatively, focusing specifically on social entrepreneurship, corporate social responsibility, fair trade, and private sustainable development. Steven G. Anderson begins by identifying the problems these programs address and then describes their core, shared principles. He follows with a general framework for defining and evaluating these and other development approaches. Separate chapters provide background on the historical development and application of each approach, as well as interpretations of the processes for implementation and the underlying behavioral assumptions related to successful outcomes. A final chapter compares each approach across a set of important program development dimensions and analyzes the utility of market-based approaches as part of a general consideration of social development strategies for the developing world.
