Author's headline result reported in abstract and conclusion is the stochastic-level/stochastic-slope column (col 1): LR price 0.27, LR income 1.33; these are the values the abstract and conclusion repeatedly cite. NOTE: Section 5 econometric testing-down instead names the stochastic-level/fixed-slope spec (col 2, LR price 0.50) as statistically preferred, so col 2 is also flagged. || "the long-term income elasticity of 1.33 and price elasticity of 0.27 suggest that the demand management policies..." (p.5473); "the stochastic level/fixed slope specification is accepted as the preferred specification for this study" (p.5472)
