Estimating Residential Water Demand in the Presence of Free Allowances
研究了包含免费配额的费率结构对居民用水量的影响，发现超出免费配额的用水对价格更敏感，而受社会气候因素影响较小，对水资源管理部门有参考价值。
The main aim of this paper is to quantify the impact of a rate structure which includes a free allowance on residential water consumption. The analysis here differs from most previous research in that it explicitly recognizes that water consumption above the free allowance, being sensitive to price, responds less to social and climatic factors than consumption below the free allowance. While the model specification and estimation procedures used here should be of interest to those interested in the demand for water, the results (using data for Adelaide, South Australia) on the determinants of water consumption should be of interest to water authorities.
