A Measure of Rationality and Welfare
针对个体行为偏离偏好最大化原则的现象，提出一种新方法，通过福利损失最小化来识别最接近显示选择的偏好关系，用于福利分析。
Evidence showing that individual behavior often deviates from the classical principle of preference maximization has raised at least two important questions: (1) How serious are the deviations? (2) What is the best way to analyze choice behavior in order to extract information for the purpose of welfare analysis? This paper addresses these questions by proposing a new way to identify the preference relation that is closest, in terms of welfare loss, to the revealed choice.
