【摘要】We develop a random choice model in which a decision maker divides the alternatives she faces into two groups, where one group is favored and thus she is more likely to choose alternatives in that group relative to alternatives in the non-favored group. We show that this seemingly specific decision making procedure in fact generalizes the Luce (1959) model (multinomial logit) and naturally captures limited consideration, reference-dependent choice, salience theory, and rational inattention. The model can be characterized by two simple weakenings of independence from irrelevant alternatives (IIA). We also characterize the generalization to K groups, which provides an axiomatic foundation for the nested logit model.
