论文摘要
决策者发现很难做出积极选择时，通常会选择延期外部选项。与具有外部选项的现有logit模型相反，本文介绍并分析了一类logit模型，其中该选项的值依赖于菜单，可以用内源确定，并且可以被解释为代理不同菜单的不同决策程度。我们专注于这些模型的 *特殊类别。我们表明，这些预测了由艰难决策引起的一些观察到的选择脱位效应，包括非单调的“滚筒”选择超负荷现象，这些现象受到存在或不存在明显显着可行的替代方案所调节的。我们说明了在潜在的优柔寡断消费者的存在下，阐述了经验离散选择分析和理论上的理论建模的拟议框架的可用性，新颖见解和解释性收益。
Decision makers often opt for the deferral outside option when they find it difficult to make an active choice. Contrary to existing logit models with an outside option where the latter is assigned a fixed value exogenously, this paper introduces and analyzes a class of logit models where that option's value is menu-dependent, may be determined endogenously, and could be interpreted as proxying the varying degree of decision difficulty at different menus. We focus on the *power logit* special class of these models. We show that these predict some observed choice-deferral effects that are caused by hard decisions, including non-monotonic "roller-coaster" choice-overload phenomena that are regulated by the presence or absence of a clearly dominant feasible alternative. We illustrate the usability, novel insights and explanatory gains of the proposed framework for empirical discrete choice analysis and theoretical modelling of imperfectly competitive markets in the presence of potentially indecisive consumers.
