Authors are deliberately neutral across the four long-run cointegrating estimators (OLS/DOLS/FMOLS/CCR), presenting them jointly as a robustness set and headlining the range -0.17 to -0.29 as "the" long-run finding; the single ECM short-run estimate (-0.08) is likewise headlined ("in the short-run the relevant elasticities are below unity", abstract), so all five coded rows are author-preferred. || "Interestingly, all the four cointegrating estimators provide quite similar long-run results thus indicating that the estimated results are robust. ... The estimated elasticities range from -0.17 to -0.29, implying that a 1% increase in the energy price is likely to decrease electricity consumption in Greece by less than 0.2% on average." (p. 802, printed); "the elasticity with respect to electricity price is below unity (-0.08)" (p. 802, printed)
