Groundwater management: Efficiency and equity considerations
地下水作为共有财产，缺乏监管时使用效率低下。本文比较不同管理工具的效率，并指出福利分配效应可能主导用户对管理的支持或反对，需通过协商达成共识。
Groundwater has the characteristics of commonly owned property, and its use is likely to be inefficient in the absence of regulation. Several management tools can be used to regulate groundwater withdrawals, with no one tool dominating the others in terms of efficiency of water use. However, the welfare distributional effects of various management schemes on individual users who vary in their derived demands for groundwater might be quite substantial, and different users may find considerably different schemes attractive. The equity problems associated with the division of management benefits may dominate the decisions about support of or opposition to groundwater management, and hence they must be undertaken with considerable care and resolved by consensus among users. Although the negotiations are expected to be extensive and complicated, there is a substantial basis for agreement because all users stand to gain; the question is, who will gain the most?
