The paper estimates a single partial-adjustment specification per sector (eq. 8 residential, eq. 9 industrial); Tables 3-4 and the results narrative present exactly these four SR/LR elasticities as the paper's findings, with no alternative specifications — all four rows are trivially preferred. || "A 100% increase in real price has a negative effect on the electricity demand making the demand decreasing by a 1,4% in the long run and 1.3% in the short run. ... In the industrial sector ... A 100% increase in real price has a negative effect on the electricity demand making the demand decreasing by a 1,8% in the long and short run." (p. 15, printed)
