Regional electricity demand in the United States
Elasticity coefficients are estimated for the different regions in the United States. Residential, commercial, industrial, and the nonprofit sectors are examined. Demographic, climatic, and regional variables are used to estimate electricity demand. The negative income estimator that appears when paired with the number of households estimator implies that residential electricity is an inferior good. Even though it is a substitute good, natural gas does not show any significance for any sectors in the economy.
