【摘要】Two strands of thinking have been attributed to prospect theory. One is built on a loss-averse reference-dependent value function which has recently been given a neurochemistry foundation (Zhong et al. 2009). This talk focuses on the other strand of prospect theory thinking having to do with how people respond to probabilistic stimuli in a nonlinear manner. We posit a salience function to model the way affective aspects of a lottery influence the extent of nonlinear response to probabilities associated with lottery outcomes and link its behavior to the underlying neurochemistry. At the level of revealed choice, our model can generate the fourfold pattern of risk attitudes including longshot bias, account for Allais behavior, and exhibit both Ellsbergian ambiguity aversion and Fox-Tversky familiarity bias. In addition, this model has implications in terms of behavioral correlations of four-fold risk attitude and gene associations which are tested using large scaled experiments.
