A Stochastic Dominance Analysis of Tillage and Crop Insurance Practices in a Semiarid Region
用随机占优分析比较半干旱地区不同耕作制度，发现风险规避型管理者偏好保护性耕作（如免耕、条耕），即使有作物保险也优于传统休耕制度，因为产量更高且燃料、劳动和维修成本更低。
Abstract Stochastic dominance analysis for tillage systems in the semiarid conditions of the central Great Plains indicates that risk‐averse managers would prefer conservation tillage systems for wheat and grain sorghum with and without the use of crop insurance instead of the traditional conventional dryland wheat‐fallow cropping system. Higher yields in conjunction with reduced fuel, labor, and repair costs more than offset increased chemical costs of the conservation systems. Increased yields generally are attributed to the soil moisture conservation characteristic of the conservation tillage systems.
