This paper characterizes a choice model interpretable as a process of elimination by aspects that resolves the major difficulties associated with the assumption of independence from irrelevant alternatives, and generalizes the choice models of Luce and Restle and is a random utility model.
Abstract
Choice is analyzed as a probabilistic process of successive eliminations. Within this general framework, the present paper characterizes a choice model interpretable as a process of elimination by aspects. It is shown that this model resolves the major difficulties associated with the assumption of independence from irrelevant alternatives, that it generalizes the choice models of Luce (1959) and Restle (1961), and that it is a random utility model. Testable consequences of this model are derived and some of its ramifications are explored.
