Abstract

We show that many models of choice can be alternatively represented as special cases of choice with limited attention (Masatlioglu, Nakajima, and Ozbay, 2012), singling out the properties of the unobserved attention filters that explain the observed choices. For each specification, information about the DM’s consideration sets and preference is inferred from violations of the contraction consistency axiom, and it is compared with the welfare indications obtained from equivalent models. Remarkably, limited attention always supports the elicitation of DM’s taste arising from alternative methods. Finally, we examine the intersections between subclasses, and we verify that each of them is independent of the others.

有限注意力和选择模型：行为等价

我们表明，许多选择模型可以替代地表示为具有有限注意力的选择的特殊情况（Masatlioglu， Nakajima和Ozbay， 2012），挑出未观察到的注意过滤器的属性来解释观察到的选择。对于每个规范，从违反收缩一致性公理中推断出决策者的考虑集和偏好信息，并将其与从等效模型中获得的福利指标进行比较。值得注意的是，有限的注意力总是支持由其他方法引起的DM味道的激发。最后，我们检查子类之间的交集，并验证它们中的每一个都是独立的。

期刊介绍： The international, interdisciplinary journal Mathematical Social Sciences publishes original research articles, survey papers, short notes and book reviews. The journal emphasizes the unity of mathematical modelling in economics, psychology, political sciences, sociology and other social sciences. Topics of particular interest include the fundamental aspects of choice, information, and preferences (decision science) and of interaction (game theory and economic theory), the measurement of utility, welfare and inequality, the formal theories of justice and implementation, voting rules, cooperative games, fair division, cost allocation, bargaining, matching, social networks, and evolutionary and other dynamics models. Papers published by the journal are mathematically rigorous but no bounds, from above or from below, limits their technical level. All mathematical techniques may be used. The articles should be self-contained and readable by social scientists trained in mathematics.
