Muhammad Yunus, the practical visionary who pioneered microcredit and, with his Grameen Bank, won the 2006 Nobel Peace Prize, has developed a new dimension for capitalism which he calls "social business. " The social business model has been adopted by corporations, entrepreneurs, and social activists across the globe. Its goal is to create self-supporting, viable commercial enterprises that generate economic growth as they produce goods and services to fulfill human needs. In Building Social Business, Yunus shows how social business can be put into practice and explains why it holds the potential to redeem the failed promise of free-market enterprise.
