Authors' clean-bill-of-health result is the dynamic linear logit model; abstract and conclusions favour the logit over the translog. Their headline own-price elasticities of electricity demand are the dynamic logit LR/SR (Table 4). || 'The dynamic logit model emerges with a remarkably clean bill of health, whereas the dynamic translog does not' (p.20, Conclusions); 'the dynamic logit model produces much more sensible estimates' (p.6).
