本文表明，经常观察到的违反IIA （independent of Irrelevant Alternatives）的现象，即相似性和吸引力效应与理性偏好的最大化是相容的，并且这些违反行为本身可以用来推断潜在的理性偏好关系。为了做到这一点，我引入了一个新的选择规则，它是基于决策者不会注意菜单上的所有项目的证据。然而，他们有一种潜在的理性偏好。模糊注意模型（FAM）具有一个基于揭示随机选择的公理，类似于揭示偏好的强公理（SARP）。该模型通过引入注意能力的概念来解释这两种效应，注意能力允许注意的互补性和可替代性。相似效应与可替代性有关，吸引效应与互补性有关。FAM嵌套了Manzini和Mariotti（2014）提出的随机考虑集和标准理性模型的文献，但没有嵌套在随机效用框架中。
This paper shows that frequently observed violations of IIA (Independence of Irrelevant Alternatives), namely the similarity and attraction effect can be compatible with the maximization of rational preferences and the violations themselves can be used to infer the underlying rational preference relation. In order to do this, I introduce a new choice rule that is based on the evidence that decision makers do not pay attention to all items in a menu. Nevertheless they have an underlying rational preference. The Fuzzy Attention Model (FAM) is characterized by an axiom based on revealed stochastic choice akin to the Strong Axiom of Revealed Preference (SARP). The model explains both effects by introducing the idea of an attention capacity that allows for complementarity and substitutability in attention. The similarity effect is related to substitutability while the attraction effect has to do with complementarity. The FAM nests the literature on random consideration sets proposed by Manzini and Mariotti (2014) and the standard rational model, but is not nested in the random utility framework.
