| Abstract: | Laboratory experiments have provided useful information about how people behave in risky situations. In particular, such experiments have allowed for the observation of many deviations from the predictions of expected utility theory. There is some dispute, however, over the effect of the use of real versus hypothetical money in these experiments and over the impact of experience. In this paper we describe auction experiments in which subjects faced a low-probability risk with either hypothetical or real-money consequences and varying amounts of experience. Using hypothetical payoffs resulted in behavior that provides a reasonable qualitative prediction of behavior with real consequences, but that seems to indicate a less diligent altitude toward spending the money as well as less concern about the risk. |
