“…Areas where DEA was frequently applied are hospitals=clinics (Birman et al, 2003;Field & Emronuznejad, 2003;190 M. F. Alam and K. Murshed-e-Jahan Gerard & Roderick 2003;Hollingsworth & Wildman, 2003;Linna et al, 2003); insurance companies=offices (Bogetoff et al, 2003); banks (Drake & Hall, 2003;Feroz et al, 2003;Luo, 2003;Prior, 2003), universities (Abbott & Doucouliagos, 2003); airports=transport (Bazargan & Vasigh, 2003) and industries (Chen, 2003;Hawdon, 2003). Agriculture (farming) also constitutes an important area where DEA was successfully applied (Bayarsaihan & Coelli, 2003;Kelvin et al, 2007;Coelli et al, 2002;Bravo-Ureta & Pinheiro, 1997;Rahman, 2003;Balcombe et al, 2007). However, studies conducted in general on aquaculture are relatively low as compared to other areas mentioned here.…”
