The all-Java symmetry-constrained own-price elasticities in Table 6 are the paper's headline demand estimates; electricity own-price = -1.043. || 'Table 6 contains the estimated own- and cross-price elasticities for Java. The symmetry restrictions from demand theory have been imposed on these estimates in order to improve precision' (p.31-32); 'The own-price elasticities are also large (in absolute terms) for electricity and LPG' (p.32).
