“…Unlike other methods of efficiency measurement like Stochastic frontier analysis, it does not impose any parametric assumptions on the data and "it can deal with production processes that have multiple inputs and outputs" (Sahoo and Acharya, 2012;Alm and Dunchan, 2014;Acharya and Sahoo, 2017). So, this method is preferred for measuring comparative efficiency of DMUs (Knechel et al, 2009;Mohanty and Sahoo, 2017). Along with that, DEA is also used to measure efficiency where the inlets and outlets are in money terms (Alm and Dunchan, 2014, Rubio and Barrilao, 2013and Thritle et.…”
