U.S. business schools are developing curriculum for aspiring impact investors, who are interested in pairing profit with social and environmental good.

"Impact investing programs, which combine social consciousness with financial returns, are popping up at universities around the world.

"'Social entrepreneurship programs have exploded in business schools across the U.S. and Europe,' says Suzanne Biegel, chief executive of Investors' Circle, a San Francisco-based impact investment group."

"Wharton, Stanford, and other leading business schools have launched social impact initiatives."
