Residential: the conclusions headline the LR price-elasticity range -0.19 to -0.42, i.e. exactly the three LR specs the authors selected into their summary Table 3a (eq 1 Cordoba TS -0.20 = 900113, praised on p. 56 as having "mayor validez descriptiva"; national CS -0.42 = 900114; Nerlovian LR -0.19 = 900115); the Nerlovian SR -0.11 (900116) is the paper's only SR residential estimate, presented in Table 3a (eq 2.1) and in the results text (p. 59). Industrial: the authors pick the "statistically most appropriate" equation per market — Cordoba Table 2b eq 4, -0.34 ("el ajuste logrado es el mas satisfactorio (R2 maximo)", p. 68) = 900493; Entre Rios whole industry eq (2), -0.89 ("la (2) es la estadisticamente mas apropiada", p. 72) = 900118; Rama 31 second equation, -1.14 ("la segunda ecuacion proporciona los resultados estadisticos mas apropiados", p. 71) = 900495 — and the conclusion's industrial range "-0,34 y -1,14" spans exactly these. NOT preferred: 900117 (national eq 3 — the authors rank the relative-price eq 4, whose -0.11 is not a coded row, as "los mas apropiados estadisticamente", p. 66, and eq 3's fuel-oil cross elasticity has "validez estadistica [que] no pudo confirmarse", p. 78); 900494 (Cordoba eq 3, "a pesar de las limitaciones que afectan la validez de sus parametros", p. 75); 900496 (Rama 31 alternative, not the selected eq); 900497/900498 (Ramas 33/38: -1.63 lies outside the concluding range and both divisions "deben tomarse con reservas... estimaciones menos confiables de los parametros", p. 77). || "la demanda residencial de electricidad del largo plazo es muy poco sensible a los cambios en su precio (el coeficiente de elasticidad estara comprendido entre -0,19 y -0,42)" [long-run residential electricity demand is very insensitive to changes in its price (the elasticity coefficient will lie between -0.19 and -0.42)] (p. 77, printed); "las evidencias empiricas reunidas permitirian tambien afirmar que la elasticidad es menor que la unidad (los coeficientes estimados estan comprendidos entre -0,34 y -1,14)" [the empirical evidence gathered would also allow us to state that the (industrial) elasticity is below unity (the estimated coefficients lie between -0.34 and -1.14)] (p. 78, printed)
