RT Journal Article SR Electronic T1 Energy Demand with Declining Rate Schedules: An Econometric Model for the U.S. Commercial Sector JF Land Economics JO Land Econ FD University of Wisconsin Press SP 86 OP 105 DO 10.2307/3147107 VO 79 IS 1 A1 Denton, Frank T.

YR 2003 UL http://le.uwpress.org/content/79/1/86.abstract AB We specify and estimate a model of the demand for electricity and natural gas in commercial buildings using data from the Commercial Building Energy Consumption Survey. Although not observed, declining rate schedules are approximated by a downward sloping function fitted to billing data for individual survey units. Marginal prices (rates), temperature variables and a large number of building characteristics are incorporated into the model as explanatory variables. Demand and rate schedule equations constitute a simultaneous system, with prices and quantities jointly determined. The effects on price elasticities of using (endogenous) marginal rather than (exogenous) average prices are estimated to be quite large. (JEL Q41)
