Paper reports exactly ONE specification per sector per horizon (Table 7 Johansen LR, Table 6 VECM SR, five sectors each); no competing specifications exist, and all ten estimates are jointly presented as "the" findings in the results narrative and conclusions (Section 6 repeats the LR/SR elastic-vs-inelastic pattern by sector), so all rows are trivially preferred. || "Price elasticity at aggregate, residential, industrial, commercial and agriculture sectors is -0.853, -1.743, -0.558, -1.834, and -1.668 respectively." (p. 134, printed; SR twins: "If short run price elasticities are considered the result of table (6) determine them as having negative signs, again the price elasticities in short run for all five models is less than unity confirming electricity as a necessity in the short run.", p. 135)
