我们建立了一个有限理性的代理人谁遭受有限的注意力。代理认为每个可行的替代品与一个给定的（不可观察的）概率，注意力参数，然后选择的替代品，最大化的一组考虑的替代品的偏好关系。我们发现，这种随机选择规则是唯一的一个，删除任何其他替代品的选择概率的影响是不对称的和菜单独立的。偏好关系和注意参数都是由随机选择数据唯一确定的。
We model a boundedly rational agent who suffers from limited attention. The agent considers each feasible alternative with a given (unobservable) probability, the attention parameter, and then chooses the alternative that maximizes a preference relation within the set of considered alternatives. We show that this random choice rule is the only one for which the impact of removing an alternative on the choice probability of any other alternative is asymmetric and menu independent. Both the preference relation and the attention parameters are identified uniquely by stochastic choice data.
