Preference Reversals for Ambiguity Aversion
研究发现，在心理和信息条件不变的情况下，模糊厌恶的测量仍会出现偏好反转，且这种反转无法用属性权重依赖解释。基于随机参照点理论，不同测量方法产生不同参照点，导致支付意愿测量高估模糊厌恶。
This paper finds preference reversals in measurements of ambiguity aversion, even if psychological and informational circumstances are kept constant. The reversals are of a fundamentally different nature than the reversals found before because they cannot be explained by context-dependent weightings of attributes. We offer an explanation based on Sugden's random-reference theory, with different elicitation methods generating different random reference points. Then measurements of ambiguity aversion that use willingness to pay are confounded by loss aversion and hence overestimate ambiguity aversion. This paper was accepted by Teck Ho, decision analysis.
