Weak Disposability in Nonparametric Production Analysis with Undesirable Outputs
指出非参数生产分析中弱可处置性的传统建模隐含了所有企业采用统一减排因子的假设，这与现实中企业边际减排成本不同、应差异化减排的实际情况相矛盾，并提出一种允许非统一减排因子且保持模型线性结构的新方法。
Weak disposability of outputs means that firms can abate harmful emissions by decreasing the activity level. Modeling weak disposability in nonparametric production analysis has caused some confusion. This article identifies a dilemma in these approaches: conventional formulations implicitly and unintentionally assume all firms apply uniform abatement factors. However, it is usually cost‐effective to abate emissions in those firms where the marginal abatement costs are lowest. This article presents a simple formulation of weak disposability that allows for non‐uniform abatement factors and preserves the linear structure of the model.
