Total factor productivity change of MENA microfinance institutions: A Malmquist productivity index approach

The main purpose of this paper is to investigate productivity changes of 33 Middle East and North Africa microfinance institutions over the period of 2006-2011 by using the Malmquist productivity index (MPI) method and a balanced panel dataset of 198 observations. The empirical findings indicate that the microfinance industry has reported overall productivity regress in the study period even though all the MENA MFIs have positive TFP growth with the exception of the year 2010-2011. In addition, our study indicates that over the period the Malmquist productivity change experienced by the MENA microfinance industry as a whole has averaged 4.9% annually which was mainly attributed to technical efficiency change. The study reveals also that the industry as a whole has exhibited a decline in technological change (2.9% decrease over the period) and suggested that there has been a deterioration in the performance of the best practicing MFIs. By decomposing the Malmquist index, the result showed that during the study period the MENA MFIs have experienced mainly an increment of pure technical efficiency (improvement in management practices) rather than an improvement in optimum size. Overall, an essential strategic implication for the MENA microfinance industry is that they need to pursue a technological progress in order to meet the dual objectives of reaching many poor people and financial sustainability.
