We experimentally test the truth-telling mechanism proposed by Montero (2008) for eliciting firms' abatement costs. We compare this mechanism with two well-known alternative allocation mechanisms, free and costly allocation of permits at the Pigouvian price. Controlling for the number of firms and the firms' maximal emissions, we find that, in line with the theoretical predictions, firms over-report their maximal emissions under free allocation of permits and under-report these under costly allocation of permits. Under Montero's mechanism, by contrast, firms almost always report their maximal emissions truthfully. However, in terms of efficiency, the difference between Montero's mechanism and costly allocation disappears with industries including more than one firm. 相似文献

Three different sizes of hog farms were selected to analyze the carbon emissions reduction and the cost–benefit of three methane digester systems. The sizes of the digesters are 2,200, 2,200 and 800 m3, respectively. The sales of slaughter hogs from them are 50,000, 35,000 and 10,000 head, respectively. The carbon emissions reductions were 5,237, 4,017, and 1,334 tons, respectively. The results show that while the methane digester systems have a significant effect on carbon emissions reduction, it is difficult to operate the systems sustainably. If the carbon emissions reduction can be traded at high enough prices in the carbon offset markets, then the systems will be profitable and sustainable. Newly established China's domestic carbon offset market could provide this possibility, but more government support is needed. In addition, this study shows that scale economies make the digester adoption relatively more profitable for larger farms than smaller ones. 相似文献

We consider contracting of a principal with an agent if multilateral externalities are present. The motivating example is that of an international climate agreement given private information about the willingness-to-pay (WTP) for emissions abatement. Due to multilateral externalities the principal uses her own emissions besides subsidies to incentivize the agent and to assure his participation. Optimal contracts equalize marginal abatement costs and, thus, can be implemented by a system of competitive permit trading. Moreover, optimal contracts can include a boundary part (i.e., the endogenous, type dependent participation constraint is binding), which is not a copy of the outside option of no contract. Compared to this outside option, a contract can increase emissions of the principal for types with a low WTP, and reduce her payoff for high types. Subsidies can be constant or even decreasing in emission reductions, and turn negative so that the agent reduces emissions and pays the principal. 相似文献

机制设计理论是研究在市场失灵的情况下,如何设计一套机制达到既定社会目标的理论。而环境问题的特殊性质使得单纯依靠市场无法合理有效的解决环境问题,这就需要机制设计这一理论的指导。基于机制设计理论的原理,已探索出很多环境政策,有效的预防并解决了污染问题,使公众利益与社会的总体利益达到了“激励相容”。本文在以排污税、排污权交易等环境政策的设计为例,探讨了机制设计理论在环境政策制定中的应用,同时分析了机制设计理论存在的问题,指出在经济全球化的背景下,依靠机制设计理论解决环境问题遇到的瓶颈,提出了利用机制设计理论制定环境政策未来的可能方向和着力点。 相似文献
