The Welfare Economics of Optional Water Metering
建立了一个适用于水务行业的分散计量决策模型，分析了家庭自主选择是否安装水表的效率，并评估了英格兰和威尔士免费提供水表的政策。
A model of decentralised metering decisions that applies to the water industry is developed. The social benefit of metering is higher the more sensitive demand is to the price. Allowing households to choose whether or not to have meters is efficient when only small households should have meters but does not work when the regulator does not know household characteristics and only larger households should have meters. The policy of requiring meters to be provided free, which has been adopted in England and Wales, is analysed. Copyright © The Author(s). Journal compilation © Royal Economic Society 2009.
