The Economic Constitution of the United States
介绍美国的经济宪法，即OMB A-4号通告，该通告指导联邦监管的监管影响分析，包括成本收益量化，2023年修订后新增行为经济学、贴现率、代际影响、分配效应及难以量化的效益成本等内容，并指出仍存在诸多未解问题。
The United States has an Economic Constitution, governing federal regulation, and explaining how to conduct regulatory impact analysis, with reference to quantification and monetization of the costs and benefits of proposed and final regulations. Known as OMB Circular A-4, the Economic Constitution of the United States was thoroughly revised in 2023, with new directions on behavioral economics and nudging; on discount rates and effects on future generations; on distributional effects and how to account for them; and on benefits and costs that are hard or impossible to quantify. The revised document leaves numerous open questions, involving (for example) the valuation of human life, the valuation of morbidity effects, and the value of the lives of children.
