Any Non‐welfarist Method of Policy Assessment Violates the Pareto Principle
证明，任何不纯粹依据个人效用（即非福利主义）来评估社会福祉的政策方法，都会违背帕累托原则，对关注政策评估基础的经济学者和政策制定者有参考价值。
The public at large, many policymakers, and a number of economists hold views of social welfare that are non-welfarist. That is, they attach some importance to factors other than the effects of policies on individuals' utilities. We show, however, that any non-welfarist method of policy assessment violates the Pareto principle.
