AI总结：
本文提出一种权力对数模型，研究决策冲突中外部选项价值依赖菜单的特性，解释了硬决策导致的非单调选择过载现象，为双头垄断模型和离散选择分析提供新视角。
摘要：
决策者在难以做出主动选择时往往选择延期外部选项。与现有将外部选项值固定外生赋值的对数模型不同，本文引入并研究了一类外部选项值依赖菜单、可能内生决定的对数模型。我们聚焦于权力对数模型这一特殊类别，证明该模型能解释由硬决策导致的观察到的选择延期效应，包括由明显主导可行替代品存在与否调节的非单调“过山车”选择过载现象。我们展示了所提框架在双头垄断建模和实证离散选择分析中的可用性、新见解和解释增益。
英文摘要：
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 studies 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 explain 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 duopolistic modelling and empirical discrete choice analysis.
