摘要：The objective of the study was to measure the risk-adjusted efficiency of banks in24 emerging economies for the period of 1999–2013. A two-stage network data envelopmentanalysis (DEA), with separate deposit mobilization and loan financing stages was used. Efficiencywas measured using directional distance functions with DEA, featuring non-performing loans asundesirable outputs. The distributions of efficiency scores were different when credit quality wastaken into account. The distribution of efficiency scores varied systematically with accumulation ofnon-performing loans across regions. The financial crisis of 2007–2008 impacted more adversely theregions that had higher proportions of non-performing loans in banks’ portfolios. The results of afollow-on non-parametric regression showed that smaller, better capitalized, and private banks weremore efficient. The conditions conducive for high levels of technical efficiency by banks were foundto be characterized by economic growth and low inflation.
