Authors call the DCC model "the preferred model to account for block pricing" (p. S176) and their Conclusions repeat only the log-log DCC electricity elasticity −0.28 as their estimate; the linear-model −0.72 (obs 900352) is reported in passing on p. S179 but not carried into the conclusions, and the joint linear system estimate (obs 900353, −0.007) has an insignificant electricity price coefficient and is discussed only for its cross-price effects. || "Our preliminary estimate of price elasticity of demand for electricity (−.28) is also slightly less than those reported elsewhere."
