利用美国西部四个跨州区域的农场微观数据,估计了作物选择、供给、土地分配和水需求函数,发现水价对作物生产的影响主要通过土地分配(粗放边际)而非短期用水量(集约边际)实现。

Abstract

Abstract Applying a model of the multioutput firm, econometric results are reported for irrigated production in four multistate regions of the American West. Cross‐sectional microdata from the Farm and Ranch Irrigation Survey and limited‐dependent variable methods are used to estimate crop‐choice, supply, land allocation, and water demand functions for field crops. Farm‐level water demand is decomposed into the sum of crop‐level water demands, and crop‐level demands are further separated into an extensive margin (land allocations) and intensive margin (short‐run water use). Response to water price (measured as groundwater pumping cost) occurs primarily at the extensive margin.
