Verified — the authors explicitly call Table 4 model (9) "the complete specifications" and quote its −0.50/0.21 as their headline interpretation; all downstream analyses (Table 5 robustness, Table 6 QR, Table 7 simulations) "consider all the controls from model (9) in Table 4", and the Hausman-recommended balanced-panel FE model (Table 5 (6), obs 900392) "produced the same coefficients as model (9)", confirming it; the abstract range −0.46 to −0.56 spans Table 4 but the single preferred row is model (9). || "For the complete specifications (model (9)), a 1% increase in the residential electricity price reduces the residential consumption by 0.50%." (p. 74, printed; also "Considering model (9), a 1% increase in the average household income implies an increase of approximately 0.21% in residential-electricity consumption", p. 74)
