The systems (AIDS) estimates are the authors' central, preferred estimates; the single-equation dynamic model could not estimate a price term for electricity, so the AIDS own-price elasticity is the paper's own-price result for electricity. || 'The results confirmed to us the value of estimating demand on a systems-wide basis. Price elasticities, both own and between goods, that were not included in the single-equation estimates were successfully estimated with the AIDS model.' (p.273); 'it can be seen that the own-price elasticity of housing is -.341...' (p.272, illustrating direct reading of Table 2 own-price elasticities).
