Public Provision and Protection of Natural Resources: Groundwater Irrigation in Rural India
研究了印度北部公共地下水供给项目对水位的影响，发现当私人打井固定成本高时，公共供给能促进地下水可持续利用，可作为高监管成本下防止过度开采的替代方案。
This paper evaluates the effects of a public groundwater provision program on water tables in Northern India. I theorize that public provision leads to sustainable use of groundwater when the fixed costs for private well provision are high. I use village-level longitudinal data on aquifers and wells, and exploit the physical and technological limitations of surface pumps that generate a cost difference at a specific water depth to test this model. My findings suggest that public provision can be used as an alternative in scenarios where prohibitive monitoring costs might preclude the use of other regulatory approaches to prevent over-extraction.
