The Impact Investing Research Lab conducts academically rigorous and practically relevant research that investigates gaps between the current pricing of impact investing opportunities and their long-term business and societal impacts with the aim of advancing academic research on and best practice in impact investing. Informed by this research, we offer 10+ courses that MBA and undergraduate students can assemble into the Social and Governance factors for Business (SOGO) major or concentration, over a dozen co-curricular experiences, four Executive certificate programs, and an expanding array of industry and policy convenings. We advance Wharton’s best-in-class education of current and future leaders, equipping them with the tools, skills, and perspectives needed to navigate a world in which investing for impact is increasingly material.

The first of its kind, the IFD includes not only financial data, but also data on impact measurement, legal governance, organizational climate, and other critical aspects of impact investing.
