Eliciting Ambiguity with Mixing Bets
研究了如何通过混合赌注偏好揭示单一事件中的模糊感知与态度，实验表明人们对股票指数和其他参与者行为的模糊感知几乎与埃尔斯伯格罐一样强，凸显了模糊性在现实决策中的重要性。
Preferences for mixing can reveal ambiguity perception and attitude on a single event. The validity of the approach is discussed for multiple preference classes, including maxmin, maxmax, variational, and smooth second-order preferences. An experimental implementation suggests that participants perceive almost as much ambiguity for the stock index and actions of other participants as they do for the Ellsberg urn, indicating the importance of ambiguity in real-world decision-making.
