基于市场的手段为管理稀缺的水资源提供了广泛规定但很少执行的工具。我们估计的价格弹性需求的农业地下水在一个水区的容积定价和每月的水平井提取数据跨越17年。需求没有弹性，估计值在-0.16到-0.2之间。我们应用这个参数来计算盈余的变化，从引入农业水价，以及城市和农业用户之间的水转移的预期收益，有和没有水供应削减。相对于对所有用户统一适用的节水任务，交易可以大大降低缺水的成本。
Market-based instruments pose widely prescribed but rarely implemented tools to manage scarce water resources. We estimate the price elasticity of demand for agricultural groundwater in a water district with volumetric pricing and monthly well-level extraction data spanning 17 years. Demand is inelastic, with estimates ranging from −0.16 to −0.2. We apply this parameter to calculate the surplus change from the introduction of agricultural water pricing, and the prospective gains from water transfers between urban and agricultural users, with and without water supply curtailments. Relative to a water conservation mandate applied uniformly to all users, trading can substantially mitigate the costs of water scarcity.
