Choice by Rejection

Bhavook Bhardwaj, Kriti Manocha

摘要:

我们提出了一个有限理性的选择模型,其中代理人在使用完整的理由做出选择之前使用传递性理由消除占主导地位的替代方案。该模型与Manzini和Mariotti(2007)的两阶段模型,即理性短名单方法(RSM)有关。我们分析了模型,通过逆转的选择,并提供其行为特征。该程序满足弱显示偏好公理(WARP)的一个较弱的版本,允许最多两个逆转的选择方面的任何一对替代品的集合包含。我们表明,基本原理可以确定从可观察到的逆转的选择。我们还刻画了这个模型的一个变体,其中两个基本原理都是传递的

英文摘要:

We propose a boundedly rational model of choice where agents eliminate dominated alternatives using a transitive rationale before making a choice using a complete rationale. This model is related to the seminal two-stage model of Manzini and Mariotti (2007), the Rational Shortlist Method (RSM). We analyze the model through reversals in choice and provide its behavioral characterization. The procedure satisfies a weaker version of the Weak Axiom of Revealed Preference (WARP) allowing for at most two reversals in choice in terms of set inclusion for any pair of alternatives. We show that the underlying rationales can be identified from the observable reversals in the choice. We also characterize a variant of this model in which both the rationales are transitive
