Probability Judgment Error and Speculation in Laboratory Asset Market Bubbles
通过实验设计两种资产，分别检测非理性（概率判断错误）和投机行为，发现概率判断错误与泡沫形成相关。
Abstract In 12 sessions conducted in a typical bubble-generating experimental environment, we design a pair of assets that can detect both irrationality and speculative behavior. The specific form of irrationality we investigate is the probability judgment error associated with low-probability, high-payoff outcomes. Independently, we test for speculation by comparing prices of identically paying assets in multiperiod versus single-period markets. We establish that aggregate irrationality measured in one dimension (probability judgment error) is associated with aggregate irrationality measured in another (bubble formation).
