Revealed preference and revealed preference cycles: A survey
综述了Afriat定理的扩展与应用，该定理指出数据集与消费者最大化连续递增效用函数一致当且仅当不存在包含严格关系的显示偏好循环（GARP）。
Afriat’s Theorem (1967) states that a dataset can be thought of as being generated by a consumer maximizing a continuous and increasing utility function if and only if it is free of revealed preference cycles containing a strict relation. The latter property is often known by its acronym, GARP (for generalized axiom of revealed preference). This paper surveys extensions and applications of Afriat’s seminal result. We focus on those results where the consistency of a dataset with the maximization of a utility function satisfying some property can be characterized by a suitably modified version of GARP.
