Model 1 (basic) is the authors' headline own-price elasticity, featured in the abstract and text as the main finding; Models 2-3 are heterogeneity extensions || 'In model 1, the own price elasticity of electricity demand is estimated to be -2.477, which carries the expected sign and is statistically significant at the 1% level. This suggests that a 1% increase in residential electricity price would result in a more than 2% decline in household electricity demand' (p.4-5)
