Carbon Sequestration in Agricultural Soils: Discounting for Uncertainty
构建了一个聚合商选择性支付农民改变耕作方式以换取碳抵消的概念模型，在随机抵消和预算约束下研究最优折现，并基于爱荷华河上游流域的假设项目进行实证估计。
The study presents a conceptual model of an aggregator who selectively pays farmers for altering farming practices in exchange for carbon offsets that the change in practices generates. Under the assumption that the offsets are stochastic and that the aggregator maximizes the sum of the offsets from the purchase that he/she can rightfully claim with a specified level of confidence subject to a budget constraint, we investigate the optimal discounting of expected carbon offsets. We use the model to empirically estimate of the optimal discounting levels and costs for a hypothetical carbon purchasing project in the Upper Iowa River basin.
