Abstract:
Water demand elasticity is estimated for six user categories: residential; commercial; industrial; government; school; and total metered. Eight generalized leastβ€squares, linear regression models are derived for each user category. Explanatory variables tested are price; per capita income; resident population per user account; housing composition; and summer precipitation. Pooled crossβ€sectional and time series annual data from the city of Columbus, Ohio, and incorporated suburbs are used. The recommended regression is a partial adjustment, generalized leastβ€squares model with crossβ€sectional dummy variables. Price is a significant factor for all user categories except industry. The greatest price effect was for school accounts, followed by commercial, government, total metered, and residential. Governmental and school demands are most responsive to fluctuations in real income, followed by residential and total metered accounts. Commercial demand was unresponsive to real income. Both shortβ€run and longβ€ru...
