Rational Inattention, Optimal Consideration Sets, and Stochastic Choice
证明理性疏忽模型会导致决策者只考虑部分选项（即形成考虑集），并给出识别考虑集的条件，对研究有限注意力下的选择行为有参考价值。
We unite two basic approaches to modelling limited attention in choice by showing that the rational inattention model implies the formation of consideration sets—only a subset of the available alternatives will be considered for choice. We provide necessary and sufficient conditions for rationally inattentive behaviour which allow the identification of consideration sets. In simple settings, chosen options are those that are best on a stand-alone basis. In richer settings, the consideration set can only be identified holistically. In addition to payoffs, prior beliefs impact consideration sets. Linear inequalities identify all priors consistent with each possible consideration set.
