Representation and Inference of Lexicographic Preference Models and Their Variants
Adobe Acrobat PDF
The authors propose two variants of lexicographic preference rules. They obtain the necessary and sufficient conditions under which a linear utility function represents a standard lexicographic rule, and each of the proposed variants, over a set of discrete attributes. They characterize the measurement properties of the parameters in the representations, propose a non-metric procedure for inferring lexicographic rules from pairwise-comparison data, and describe how the method can be used to construct hierarchical market structures using conjoint data. The authors illustrate the methods with data on personal-computer preferences. They report a simulation assessing the ability of the proposed inference procedure to distinguish among alternative lexicographic models, and between linear-compensatory and lexicographic models.
