Abstract: |
This study analyzes the impact of unobserved heterogeneity on microfinance
efficiency. Using panel data for 168 microfinance institutions (MFIs) over the
period 20102015, we examine the persistence of the effect of unobserved
heterogeneity on microfinance efficiency. Using recent nonparametric and
robust techniques, we identify a latent heterogeneity factor related to the
ability of MFI managers to promote efficiency, independent of MFI size, and
analyze its impact on MFI inefficiency measures over time. We then assess the
robustness of our results to several factors: the MFI status of the MFI
(for-profit or nonprofit), the definition of the efficiency measure (social
and financial) and an observed degree of heterogeneity captured by the
percentage of women on the board. Finally, we analyze the relationship between
our unobserved heterogeneity factor and institutional and socio-economic
indicators. |
