英文文献：Groundwater Pumping by Heterogeneous Users-由不同用户抽取地下水
英文文献作者：Saak, Alexander E.,Peterson, Jeffrey M.
英文文献摘要：
Farm size is a significant determinant of both groundwater irrigated farm acreage and groundwater irrigation application rates per acre. This paper analyzes the patterns of groundwater exploitation when resource users in the area overlying a common aquifer are heterogeneous. In the presence of user heterogeneity, the common resource problem consists of inefficient dynamic and spatial allocation of groundwater because it impacts income distribution not only across periods but also across farmers. Under competitive allocation, smaller farmers pump groundwater faster if farmers have a constant marginal periodic utility of income. However, it is possible that larger farmers pump faster if the Arrow-Pratt coefficient of relative risk-aversion is sufficiently decreasing in wealth. A greater farm-size inequality may either moderate or amplify income inequality among farmers. Its effect on welfare depends on the curvature properties of the agricultural output function and the farmer utility of income. Also, it is shown that a flat-rate quota policy that limits the quantity of groundwater extraction per unit land may have unintended consequences for the income distribution among farmers.
农田面积是地下水灌溉农田面积和每英亩地下水灌溉施用量的重要决定因素。本文分析了同一含水层上覆区域在资源使用者非均质情况下的地下水开采规律。在用户异质性存在的情况下，普遍存在的资源问题是低效的动态和空间配置地下水，因为它不仅影响着不同时期的收入分配，而且影响着农民的收入分配。在竞争分配条件下，如果农民的收入边际周期效用是恒定的，那么较小的农民抽取地下水的速度会更快。然而，如果相对风险厌恶的阿罗-普拉特系数在财富上充分降低，那么规模较大的农民可能会泵得更快。农场规模更大的不平等可能会缓和或加剧农民之间的收入不平等。它对福利的影响取决于农业产出函数的曲率性质和农民收入效用。此外，研究还表明，限制单位土地地下水抽取量的定额政策可能会对农民之间的收入分配产生意想不到的后果。
