Efficiency rating of decision making units (DMUs) was long back identified as an important activity that helps both the producer and the policy maker. It requires that the DMUs are in competition, produce similar outputs combining similar inputs. Efficiency rating may be oriented or non-oriented. Twenty banks were considered to study efficiency variations pursuing output approach. For given inputs, outputs are radially projected onto the data envelopment frontier for each decision making unit. Frontier output augmentation is not possible for an efficient DMU, which is a commercial bank in the...
