The paper reports exactly one long-run cointegrating equation (Table 2) and one short-run ECM (Table 3); both are headlined in the abstract and conclusions as the paper's findings (SR normal good, LR inferior good), so both rows are preferred. || "Results from a dynamic error correction modeling approach indicate that residential electricity consumption reacts in statistically significant manners to changes in real price, real income, and cold weather. In the short-run, residential electricity is a normal good in this metropolitan economy. In the long-run, residential electricity appears to be an inferior good in Seattle." (p. 1693, printed)
