The Rich Domain of Risk
通过两个实验发现，客观概率事件并非单一不确定性来源；简单与复杂风险事件下行为显著不同，且对复杂风险的态度与模糊性及复合彩票态度紧密相关，挑战了现有模糊性厌恶模型。
We report on two experiments challenging the common assumption that events with objective probabilities constitute a unique source of uncertainty. We find that, similar to the domain of ambiguity, the domain of risk is rich in the sense that behavior is systematically different when subjects face risky bets based on simple or more complex events. Furthermore, we find a tight association between attitudes toward complex risky bets and attitudes toward both ambiguity and compound lotteries. These results raise questions about the characterization of ambiguity aversion and the modeling of decisions under uncertainty. This paper was accepted by James Smith, decision analysis.
