Authors' headline results are the LONG-RUN own-price elasticities from the cointegration (Table 4), not the short-run VEC coefficients that were coded || 'Results show long-term elasticities of electricity use above unity for income, and of the order of -0.3 to -0.4 for prices' (p.183 abstract); 'Long-term price elasticities are also significant, ranging from -0.30 for commercial to -0.43 for residential electricity' (p.191)
