英文文献：Does Pumping Pay: Groundwater Management Institutions and Cropland Values in Nebraska?
英文文献作者：Savage, Jeffrey,Ifft, Jennifer
英文文献摘要：
Conflicts over agricultural water use have been an issue in the western United States and worldwide since the widespread development of irrigation. Water management institutions serve to ration scare water resources, but can impose costs on water uses. These costs can be difficult to measure as water rights are often not tradable. The option value of irrigation, or the costs imposed when producers lose the unused right to irrigate, is especially difficult to measure. This study measures the value of pumping rights under different management institutions in Nebraska. We take advantage of temporal and spatial variation in water management across the state, as well as unique plot level data that incorporate information on cropland values, irrigation status, and physical characteristics. Preliminary results indicate that irrigation rights substantially increase cropland values, and hence likely contribute significantly to farm income.
