Beyond Revealed Preference: Choice-Theoretic Foundations for Behavioral Welfare Economics
提出一种广义的选择理论福利经济学框架，涵盖多种非标准行为模型，用“明确选择关系”替代传统显示偏好，为行为福利分析提供新工具。
We propose a broad generalization of standard choice-theoretic welfare economics that encompasses a wide variety of nonstandard behavioral models. Our approach exploits the coherent aspects of choice that those positive models typically attempt to capture. It replaces the standard revealed preference relation with an unambiguous choice relation: roughly, x is (strictly) unambiguously chosen over y (written xP ∗ y) iff y is never chosen when x is available. Under weak assumptions, P ∗ is acyclic and therefore suitable for welfare analysis; it is also the most discerning welfare criterion that never overrules choice. The resulting framework generates natural counterparts for the standard tools of applied welfare economics and is easily applied in the context of specific behavioral theories, with novel implications. Though not universally discerning, it lends itself to principled refinements. I.
