Why we chose it: For fall 2007, Duke's Fuqua School of Business adds a concentration in social entrepreneurship, which consists of six electives. Known for their research in entrepreneurship, Fuqua professors work with counterparts at other universities, such as NYU, to devise innovative methods for teaching social entrepreneurship, and to create tools with which to measure the impact of businesses on communities. Students get real-world experience via Fuqua On Board, a program that places MBA students on the boards of local non-profits during the school year. While working for the organization, students serve as non-voting board members. "We see great value in developing deep relationships through this program," says CASE managing director Beth Anderson. "It allows students to draw from the business world to promote the entrepreneurial pursuit of social impact."
