“…Apart from the compatibility of the data we have allowed for the random noise in the form of excluded variables, misspecification of model, luck and measurement errors as inefficiency variables. Following the studies done for estimation of energy efficiency/inefficiency by (Haider & Mishra, 2021), (Mendonca, Pereira, Alberto, & Pessanha, 2020), (Hu & Honma, 2014), (Adom, 2019), (Adoma, Amakyeb, Abrokwac, & Quaidood, 2018), (Weyman-Jonesa, Boucinhab, & Inácioc, 2016), (Lin & Du, 2014), (Boyd & Lee, 2019), (Chen, Barros, & Borges, 2015), (Filippini & Hunt, 2011, (Evans, Filippini, & Hunt, 2013), (Filippini, et.al 2014), (Yu & Guo, 2016) and the most recent study by (Twerefou & Abeney, 2020) we have used SFA approach for the electricity consumption efficiency frontier estimation.…”
