论文摘要
我们对具有主观不确定性的货币赌博产生了不完全的偏好。受试者排名赌博，这些排名用于估计偏好；付款基于估计的偏好。大约40％的受试者表达不完整，但很少这样做。对于具有精确和不精确的人，并且在具有客观不确定性的环境中，不完整的人是相似的，这表明它是由于不精确的口味而不是不准确的信念而导致的。当我们强迫受试者选择时，我们会观察到更多的不一致和偏好逆转。有证据表明，除了直接测量的情况外，除了多达98％的受试者外，有不完整的性质是间接揭示的。
We elicit incomplete preferences over monetary gambles with subjective uncertainty. Subjects rank gambles, and these rankings are used to estimate preferences; payments are based on estimated preferences. About 40\% of subjects express incompleteness, but they do so infrequently. Incompleteness is similar for individuals with precise and imprecise beliefs, and in an environment with objective uncertainty, suggesting that it results from imprecise tastes more than imprecise beliefs. When we force subjects to choose, we observe more inconsistencies and preference reversals. Evidence suggests there is incompleteness that is indirectly revealed -- in up to 98\% of subjects -- in addition to what we directly measure.
