Strategic Behavior, Private Information, and Decentralization in the European Union Emissions Trading System
研究了欧盟排放交易体系中碳配额供给由成员国分散决定还是由中央统一决定，分析了成员国策略行为和成本信息隐私对总减排成本的影响。
In the European Union Emissions Trading System, the supply of carbon permits is determined in a decentralized manner by Member States. Alternatively, the supply could be determined by an EU central authority. We analyze whether decentralization leads to lower total abatement costs under various assumptions about the behavior of Member States and the privacy of information about their abatement costs. If Member States do not behave strategically, then decentralization is preferred, regardless of whether abatement costs are private information. If the Member States behave strategically, then decentralization may or may not be preferred, depending on the degree of uncertainty about abatement cost parameters, the variation in emission endowments, and the number of Member States.
