影子价格，也称为边际减排成本，为支持二氧化碳、二氧化硫和氮氧化物的环境监管政策提供了宝贵的指导方针，二氧化碳、二氧化硫和氮氧化物是气候变化的关键贡献者。本文是对已有模型的补充，提出了一种方向性边际生产率(DMP)方法来估计方向性影子价格(DSP)，该方向性影子价格表示三种排放之间的可替代性，并被联合估计。我们将该方法应用于美国燃煤电厂在1990至2010年间产生的二氧化碳、二氧化硫和氮氧化物的案例研究。我们发现，数字信号处理器显示的最大影子价格是目前文献中估计的最大影子价格的1.1倍。我们的结论是，单独估计每种副产品的影子价格可能会导致对边际生产率的高估和对影子价格的低估。(C)2015爱思唯尔B.V.保留所有权利。
Shadow prices, also termed marginal abatement costs, provide valuable guidelines to support environmental regulatory policies for CO2, SO2 and NOx, the key contributors to climate change. This paper complements the existing models and describes a directional marginal productivity (DMP) approach to estimate directional shadow prices (DSPs) which present substitutability among three emissions and are jointly estimated. We apply the method to a case study of CO2, SO2 and NOx produced by coal power plants operating between 1990 and 2010 in the United States. We find that DSP shows 1.1 times the maximal shadow prices estimated in the current literature. We conclude that estimating the shadow prices of each by-product separately may lead to an overestimation of the marginal productivity and an underestimation of the shadow prices.
