Challenges from State-Federal Interactions in US Climate Change Policy
分析了美国州级可再生能源和汽车燃料经济性标准与联邦政策重叠时可能无法有效减少全国温室气体排放、损害成本效益的问题，指出基于价格的联邦政策可避免此类冲突。
With a focus on two sorts of regulation—renewable electricity and clean energy standards, and automobile fuel-economy standards—we analyze problematic interactions that arise when state policies are nested within the domain of Federal policy. Here state efforts may fail to reduce greenhouse gas emissions nationally, and may compromise cost-effectiveness. Difficulties from overlapping regulations are avoidable through price- (as opposed to quantity-) based Federal policy. We identify some potentially positive interactions between state and Federal policies, and identify rationales for state action when Federal and state policies do not overlap.
