The Choices of Irrigation Technologies in California
用计量方法分析加州中央谷地果农选择滴灌、喷灌或地面灌溉的影响因素，发现水价高、用地下水、种坚果和地理位置会增加采用滴灌和喷灌的可能性，并说明提价能促进节水。
Abstract This paper introduces an econometric technique to analyze the factors affecting the land shares of alternative irrigation technologies in agriculture. It estimates the likelihood of use of drip, sprinkler, and surface irrigation by fruit growers in the Central Valley of California. Higher water costs, the use of groundwater, the production of nuts, and location are found to increase the likelihood of using drip and sprinkler irrigation. The results are used to demonstrate the effectiveness of water price increases in inducing water conservation.
