论文摘要
实验表明，人们未能考虑其选择之间的相互依存关系 - 他们没有广泛的括号。相反，研究人员通常认为人们狭窄的括号，但现有的设计没有测试。我们设计了一个新颖的实验，并揭示了某人如何括起其选择的偏好测试。在风险，社会分配和引人入胜的购物实验的投资组合分配中，40-43％的受试者与狭窄的括号一致，而0-16％的受试者与宽大的括号一致。调整每个模型的预测精度，有74％的受试者可以通过狭窄的括号，13％的范围来描述，通过宽括号为13％，中间病例最好地描述6％。
Experiments suggest that people fail to take into account interdependencies between their choices -- they do not broadly bracket. Researchers often instead assume that people narrowly bracket, but existing designs do not test it. We design a novel experiment and revealed preference tests for how someone brackets their choices. In portfolio allocation under risk, social allocation, and induced-value shopping experiments, 40-43% of subjects are consistent with narrow bracketing and 0-16% with broad bracketing. Adjusting for each model's predictive precision, 74% of subjects are best described by narrow bracketing, 13% by broad bracketing, and 6% by intermediate cases.
