Preferences for One-Shot Resolution of Uncertainty and Allais-Type Behavior
研究个体在逐步感知风险时更厌恶风险的现象，提出一次性解决不确定性的偏好，并证明其与阿莱型实验中的静态偏好等价，有助于理解风险决策和信息偏好。
Experimental evidence suggests that individuals are more risk averse when they perceive risk gradually.We address these …ndings by studying a decision maker (DM) who has recursive preferences over compound lotteries and who cares about the way uncertainty is resolved over time.DM has preferences for one-shot resolution of uncertainty (PORU) if he always prefers any compound lottery to be resolved in a single stage.We establish an equivalence between dynamic PORU and static preferences that are identi…ed with the behavior observed in Allais-type experiments.The implications of this equivalence on preferences over information systems are examined.We de…ne the gradual resolution premium and demonstrate its magnifying e¤ect when combined with the usual risk premium.In an intertemporal context, PORU captures "loss aversion with narrow framing".
