This paper uses stochastic frontier analysis (SFA) to examine whether there is a trade-off between outreach to the poor and efficiency of microfinance institutions (MFIs). Using a sample of more than 1,300 observations, our study suggests that outreach and efficiency of MFIs are indeed...

Summary This paper uses stochastic frontier analysis to examine whether there is a trade-off between outreach to the poor and efficiency of microfinance institutions (MFIs). We find convincing evidence that outreach is negatively related to efficiency of MFIs. More specifically, we find that...

This paper develops a non-linear stochastic frontier (SF) model. The main advantage of this model over standard SF models is that the model does not need an assumption for the distributional form of the inefficiency component. Another advantage of the developed model is that it can be used to...

Stochastic frontier models all need an assumption on the distributional form of the efficiency component. Generally this efficiency component is assumed to be half normally, truncated normally, or exponentially distributed. This paper shows that the exponential distribution is, just like the...

The positive relation between financial development and economic growth seems to have weakened in recent years and when analyzing only developed countries. We suggest here that banks' relative ability to intermediate funds cost-efficiently is a quality-based measure of financial development that...
