“…In this connection, Chaudhuri and Das (2006) used stochastic frontier analysis (SFA) to measure efficiency of the industry. Non-parametric data envelopment analysis (DEA) has been applied by some studies (Mahajan, Nauriyal, & Singh, 2014, 2015; Mazumdar & Rajeev, 2012; Mazumdar, Rajeev, & Ray, 2009; Pannu, Dinesh Kumar, & Farooquie, 2011; Saranga, 2007; Saranga & Phani, 2009; Mahajan et al, 2014a, 2014b, 2015) to measure efficiency of the industry. Internationally, only a few empirical studies (Gonzalez & Gascon, 2004; Hashimoto & Haneda, 2008) have analysed efficiency of this industry using DEA.…”
