The allocative efficiency and conservation potential of water laws encouraging investments in on‐farm irrigation technology
研究了美国西部鼓励私人灌溉者提高农场灌溉效率的节水法规，在多种水文经济条件下能否促进整个流域的用水经济效率和节水，发现俄勒冈州立法模式效果最差。
Abstract Agricultural water conservation statutes are emerging in the West encouraging private irrigators to improve on‐farm irrigation efficiency as a basinwide conservation measure. We investigate whether private improvements promote the economic efficiency and conservation of water use basinwide under a wide variety of hydroeconomic circumstances. The standard of efficiency is how an irrigation district manager should optimally invest in improving the irrigation efficiencies of individual farms located along a stream while internalizing intrabasin allocative externalities of these investments. The results indicate that the popular Oregon legislative model may be the least effective in conserving water and promoting economically efficient water allocation.
