Data Envelopment Analysis (DEA) is widely applied in evaluating the efficiency of banks since it is a method capable of evaluating the efficiency of decision-making units in utilizing multiple inputs to produce multiple outputs. However, some outputs of banks, in fact, possess fuzzy...

Many prior studies on Indian banking efficiency have typically regressed non-parametric estimates of production efficiency on environmental variables in a two-stage process. However, Simar and Wilson (2007) have demonstrated that the studies that use such conventional approaches are invalid due...
