A simplified test for preference rationality of two-commodity choice
提出一种简化检验方法，判断两商品消费集的选择数据是否满足广义显示偏好公理（GARP），从而检验偏好或效用最大化假设，并给出算法及实验数据应用示例。
We provide a simplified test to determine if choice data from a two-commodity consumption set satisfies the Generalized Axiom of Revealed Preference (GARP), and thus the preference or utility maximization hypothesis. We construct an algorithm for this test and illustrate its application on experimental choice data.
