Author frames the relative-price-of-energy elasticities as the policy-relevant ones, but reports both a short-run (ECM/Table 5) and long-run (Table 3) electricity own-price elasticity; no single headline is singled out for electricity's own fuel-specific price. Coded cell (beta2 SR electricity, -0.70) is a legitimate own-price estimate. || 'The study must, therefore, focus on the relative price of energy elasticities of fuel demand. The cointegration approach has produced short- and long-run estimates of these elasticities.' (p.241)
