"In her book Social Entrepreneurship for the 21st Century, Georgia Levenson Keohane provides a great insight into the emergence of social business and entrepreneurship.

"Entrepreneurship and venture thinking don't reside only in Silicon Valley; they can be found in the nonprofit sector, and they are changing the social fabric of nations and cultures around the world. Just how the nonprofit sector has evolved into a powerful agent of social change is the story expertly told by Georgia Levenson Keohane in Social Entrepreneurship for the 21st Century. This is a hugely important book for those who want to understand the nonprofit world and its evolving role." --ELIOT SPITZER, former governor of New York and host of Current TV's Viewpoint

"A timely, comprehensive, and well-written perspective on one of the most powerful, positive forces for social change in our world today. Keohane's book not only synthesizes her state-of-the-art knowledge of the field, but brings new insight into impact investing, the growing role of the social capital markets, the essentiality of valid performance measures, and the blurring of the lines between the social, public, and private sectors." --WILLIAM F. MEEHAN III, Raccoon Partners Lecturer in Management, Stanford Graduate School of Business and Director Emeritus, McKinsey and Company

"There's been much talk of a 'social entrepreneurship' movement over the past decade. But what is it? How new is it? How has it influenced nonprofits as well as the private and public sectors? What are its virtues and its limitations? What risks are there in its embrace? Georgia Levenson Keohane has provided the most comprehensive, deeply researched, critical examination of social entrepreneurship to date." --PHIL BUCHANAN, president of the Center for Effective Philanthropy
