摘要： 采用Roca的实验范式，要求被试给出WTP（买进模糊或风险备择项所愿意付出的最大价格）和WTA（放弃模糊或风险备择项所愿意接受的最小价格），进一步去检验这个结论的有效性，结果没有发现模糊寻求的偏向。不一致的原因可能是WTP和WTA分别要求给出的是价格的上限和下限，这种差异对被试的决策是有影响的。

Abstract: Previous studies found that people are ambiguity aversion, and are willing to pay the ambiguity medium to address this ambiguity. In Roca’s study, he made ambiguity decision combined with endowment effect and found that subjects preferred to retain ambiguous alternative item, rather than make exchange from ambiguous alternative to risky items, there have been a reversal in the decision. We take Roca’s experimental paradigm to test the validity of this conclusion. Subjects were required to give WTP (the willingness to pay the maximum price when buying the ambiguity option or risky option) and WTA (the willingness to accept the minimum price when giving up the ambiguity option or risky option). The result founded that subjects didn’t show ambiguity seeking. The inconsistency maybe that WTP gave a cap of price and WTA gave a floor to the price. The deviation of prices received is influential on subject’s decision making.

Key words: ambiguity aversion, endowment effect, ambiguity medium, the status quo bias.
