In development circles, there is now widespread consensus that social entrepreneurs represent a far better mechanism to respond to needs than we have ever had before—a decentralized and emergent force that remains our best hope for solutions that can keep pace with our problems and create a more peaceful world. David Bornstein's previous book on social entrepreneurship, "How to Change the World," was hailed by Nicholas Kristof in The New York Times as "a bible in the field" and published in more than twenty countries. Now, Bornstein shifts the focus from the profiles of successful social innovators in that book and teams with Susan Davis, a founding board member of the Grameen Foundation, to offer the first general overview of social entrepreneurship. In a Q&A format allowing readers to go directly to the information they need, the authors map out social entrepreneurship in its broad context.
