Abstract A decision maker, who is overwhelmed by the number of available alternatives, limits her consideration. We investigate a model where a decision maker’s capacity determines whether she is overwhelmed: She considers all the available alternatives if their number does not exceed her capacity; otherwise, she applies a shortlisting procedure to reduce the number of alternatives to within her capacity. We show how to deduce the decision maker’s capacity, her preference and the alternatives that she considers from the observed behavior. Furthermore, we provide the necessary and sufficient conditions for a consideration function to be derived by the shortlisting procedure with a limited capacity.

能力有限的入围程序

摘要 决策者因可用替代方案的数量而不知所措，限制了她的考虑。我们研究了一个模型，其中决策者的能力决定了她是否不堪重负：如果数量不超过她的能力，她会考虑所有可用的替代方案；否则，她会采用入围程序，以在其能力范围内减少备选方案的数量。我们展示了如何从观察到的行为中推断出决策者的能力、她的偏好和她考虑的替代方案。此外，我们为有限能力的入围程序推导出对价函数提供了必要和充分条件。
