An Efficiency Approach to the Evaluation of Policy Changes
提出一种基于帕累托准则而非分配价值判断的效率方法来评估政策变化，通过比较现状下其他可能变化而非前后效用分配，并应用于多个例子。
This paper describes an efficiency approach to the evaluation of policy changes. Rather than comparing the utility allocations that arise before and after a policy change is introduced, this approach evaluates a policy change by comparing it with other possible changes which might be made from the status quo. The main merit of the approach is that it is founded on the Pareto criterion rather than on a distributional value judgement. The paper provides a precise statement of the approach and applies it to a number of examples. Some objections to the approach are also anticipated and discussed.
