The study (i) reviews the definitions and concepts of social enterprises, (ii) outlines the landscape across 10 selected countries in Asia and Latin America, (iii) discusses challenges to scaling as faced by social enterprises, and (iv) presents suggestions for development banks to extend support to social enterprises through public and private sector investments. The study categorizes social enterprises and argues that the comparative advantage of development banks is to support selected social enterprises that are commercially bankable and have the base of the pyramid (BOP) at the core of their business operations. Development banks can support these enterprises—considered as the inclusive businesses of the future—through investing in impact funds and/or public sector loans.
