Four Revealed Preference Tables
研究了当维持的假设改变时，显示偏好推断如何变化，分析了四种模型，澄清了现有文献中的一些方面。
In this article we consider how revealed preference inferences change when the assumptions maintained are altered. In the first two models, a demand correspondence is generated by utility maximization; the conditions on the underlying preference relation differ only with respect to the strength of the convexity assumptions. In the second two models, alternative revealed preference axioms are imposed directly on a demand correspondence. One of these axioms is Samuelson's Weak Axiom of Revealed Preference; the other is a variant of this axiom which allows for nonuniqueness in the demand correspondence. The results of our analysis clarify aspects of the existing revealed preference literature.
