A Model of Probabilistic Choice Satisfying First-Order Stochastic Dominance
提出了一个在风险下进行概率二元选择的新模型,该模型始终满足一阶随机占优,由四个标准公理和两个新公理推导得出,比现有模型更好地拟合实验数据,并可扩展至消费者需求等领域。
This paper presents a new model of probabilistic binary choice under risk. In this model, a decision maker always satisfies first-order stochastic dominance. If neither lottery stochastically dominates the other alternative, a decision maker chooses in a probabilistic manner. The proposed model is derived from four standard axioms (completeness, weak stochastic transitivity, continuity, and common consequence independence) and two relatively new axioms. The proposed model provides a better fit to experimental data than do existing models. The baseline model can be extended to other domains such as modeling variable consumer demand.
