Choice overload and asymmetric regret
提出了一个选择过载模型，描述决策者在更大选择集中更倾向默认选项，并刻画了不对称后悔：决策者不考虑选择默认选项的后悔，但普通选项的价值受后悔影响。
We propose a model of 'choice overload,' which refers to a stronger tendency to select the default option in larger choice problems. Our main finding is a behavioral characterization of an asymmetric regret representation that depicts a decision maker who does not consider the possibility of experiencing regret for choosing the default option. By contrast, the value of ordinary alternatives is subject to regret. The calculus of regret for ordinary alternatives is identical to that in Sarver's (2008) anticipated regret model, despite the fact that the primitives of the two theories are different. Our model can also be applied to choice problems with the option to defer the decision.
