论文摘要
我们描述了一种选择的上下文敏感模型,其中选择过程不仅是由项目的吸引力,而且还由它们的语义(“显着性”)所塑造的。所有项目均根据显着性的关系进行排名,并且每个项目都有线性顺序。从菜单中选择单个元素是由菜单中最显着项目索引的线性订单之一证明的。通用模型为任何观察到的行为提供了结构化的解释,并允许我们对决策者的“情绪化”建模,这是需要选择与项目一样多的选择的典型选择。渐近的所有选择都是喜怒无常的。我们挑出了一个线性显着性模型,其中显着性顺序是传递和完整的,并以行为属性为特征,称为Warp(S)。线性显着性可合理化的选择只能表现出不受冲突的违规行为。我们还提供数值估计值,该估计显示了该有限合理性的可检验模型的高选择性。
We describe a context-sensitive model of choice, in which the selection process is shaped not only by the attractiveness of items but also by their semantics ('salience'). All items are ranked according to a relation of salience, and a linear order is associated to each item. The selection of a single element from a menu is justified by one of the linear orders indexed by the most salient items in the menu. The general model provides a structured explanation for any observed behavior, and allows us to to model the 'moodiness' of a decision maker, which is typical of choices requiring as many distinct rationales as items. Asymptotically all choices are moody. We single out a model of linear salience, in which the salience order is transitive and complete, and characterize it by a behavioral property, called WARP(S). Choices rationalizable by linear salience can only exhibit non-conflicting violations of WARP. We also provide numerical estimates, which show the high selectivity of this testable model of bounded rationality.
