Microfinance Business Models

The microfinance sector is an example of a sector in which firms with different business models coexist. Next to pure for-profit microfinance institutions (MFIs), the sector has room for non-profit organizations, and includes 'social' for-profit firms that aim to maximize a double bottom line and do well while doing good. We introduce a benchmarking approach that accommodates these three business models and allows us to estimate the efficiency of MFIs when they operate true to their business model, but also when they drift away from their original design. Using a simple model, we hypothesize that it is more difficult to operate efficiently when pursuing a double bottom line. Our empirical results for a large sample of MFIs are in line with this hypothesis: pure for-profit and non-profit FMIs are more efficient than 'social' for-profit MFIs. In addition, efficiency decreases for all MFIs when they move away from their original business model. Increasing the risk of the loan portfolio reduces efficiency and lending to woman increases efficiency. Finally, our finding that multiple lending to borrowers is efficiency-enhancing may help explain the mission drift in microfinance.
