“…The dynamic inefficiency indicators (cost, technical and allocative inefficiencies) were estimated for each year separately, relative to the metafrontier based on observations of firms in all regions, and to a region‐specific frontier. Following previous literature (e.g., Kapelko et al ., 2014; Dakpo, 2015; Kapelko, 2017), the directional vector used in the computations is g x = x 0 n , n = 1, …, N , for variable inputs and g I = 0.2 K 0 f , f = 1, …, F , for investment. As noted in section 3, we assume CRS technology in our calculations.…”
