Authors prefer the dynamic linear-logit model on energy-use-only data: it dominates the translog on global properties and excluding nonenergy fuels is argued to better reflect actual substitution potential; long-run own-price electricity elasticity from that model = -.207 (SR -.050). || 'a dynamic linear logit model is shown to provide global properties superior to those of a comparable dynamic translog model' and 'Excluding fuels used for nonenergy purposes yields larger estimates of the price elasticities for coal and oil and indicates generally greater potential for interfuel substitution than when using aggregate data' (abstract, p.459)
