Testing rank‐dependent utility theory for health outcomes
在健康情境下比较了等级依赖效用理论（RDU）与期望效用理论（EU）的描述性表现，发现当存在确定选项时RDU能解释EU的违背，但双方均为风险选项时RDU未表现出改进。
Systematic violations of expected utility theory (EU) have been reported in the context of both money and health outcomes. Rank-dependent utility theory (RDU) is currently the most popular and influential alternative theory of choice under circumstances of risk. This paper reports a test of the descriptive performance of RDU compared to EU in the context of health. When one of the options is certain, violations of EU that can be explained by RDU are found. When both options are risky, no evidence that RDU is a descriptive improvement over EU is found, though this finding may be due to the low power of the tests.
