The microfinance sector has room for pure for-profit microfinance institutions (MFIs), non-profit organizations, and “social” for-profit firms that aim to pursue a double bottom line. Depending on their business model, these institutions target different types of borrowers, change the size of their loans and adjust their loan pricing. We introduce a simple approach that accommodates a wide range of business models and allows us to estimate the operational efficiency of MFIs. Our empirical results show that MFIs with a high depth of outreach are most efficient, resulting in higher levels of outreach and profits for the same input mix.
