Abstract/conclusions headline the static-model own-price elasticity range and the overall 'price inelastic' finding; the static estimates (Table 6 cols 1-2, -0.308 and -0.281) are the -0.28 to -0.30 range explicitly cited || 'It is also concluded that the demand for residential electricity is inelastic (price elasticity -0.28 to -0.30). The statistical significance of both is high in both specifications.' (p.45)
