Other than ratio analysis, Data Envelopment analysis (DEA), a non parametric technique and Stochastic Frontier Analysis, a parametric and econometric model are the two alternative approaches available for efficiency analysis of financial institutions.
Currently, majority of studies on the performance of MFI (e.g. Tucker and Miles 2004, Koveos and Randhawa, 2004) are based on financial ratios identical to those used to measure performances in banking, e.g., the CAMEL, PEARLS and GIRAFFE ratios. Yet, as some authors (Athanassopoulos and Ballantine, 1995; Gregoriou, Messier and Sedzro, 2005, etc) have stressed that ratio analysis cannot be able to capture sufficiently the multidimensional aspect that banking activities and decisions (and by extension those of MFI) have. Indeed, this type of analysis is based on the assumption of linearity and a constant return to scale, which means that only
