Conservation Payments under Risk: A Stochastic Dominance Approach
利用边际条件随机占优规则，推导出在风险条件下确定保护支付的条件，以保障环境友好型土地利用占优。以厄瓜多尔西部乔科地区遮荫咖啡保护为例，发现所需保护支付远高于风险中性假设下的计算值，且现有土地分布对支付有显著影响。
Conservation payments can be used to preserve forest and agroforest systems. To explain landowners' land‐use decisions and determine appropriate conservation payments, it is necessary to focus on revenue risk. Marginal conditional stochastic dominance rules are used to derive conditions for determining the conservation payments required to guarantee that the environmentally preferred land use dominates. An empirical application to shaded coffee protection in the biologically important Chocó region of West Ecuador shows that conservation payments required for preserving shaded coffee areas are much higher than those calculated under risk‐neutral assumptions. Further, the extant distribution of land has strong impacts on the required payments.
