Does Efficiency Lead to Lower Prices? A New Perspective from Microfinance Interest Rates

Pricing is a central strategic decision for all companies, and is particularly sensitive for social enterprises with both financial and social objectives. High interest rates in microfinance are a topic of intense debate. Using an original database of 291 MFIs, this paper provides empirical evidence of the impact the efficiency of an MFI has on its microcredit interest rate. We use the non-parametric Data Envelopment Analysis (DEA) framework to calculate efficiency and differentiate financial and social efficiency. The results show that financial efficiency has a positive impact on interest rates, with more financially efficient MFIs having lower interest rates, while social efficiency has no impact on microcredit interest rates.
