This is the first paper to address the premium-social performance relationship upon an unbalanced panel of 66 microfinance institutions (MFIs) in the MENA region over 2004-2014. According to a fixed effects model using instrumental variables, financial sustainability is the primary determinant of premium (i.e. the financial margin), whereupon social performance has a positive albeit insignificant impact. Mature MFIs maintain financial sustainability and serve rather non-poor clients, although they tame interest rates.
