We introduce a multi-attribute model that generalizes the multinomial logit model by introducing one additional parameter. It captures framing and context effects, and allows violations of regularity, independence of irrelevant alternatives and order independence. Conceptually, the model...

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 then: (i)...

The authors model product consideration as preceding choice in a segment-level conjoint model. They propose a latent-class tobit model to estimate cardinal, segment-level preference functions based on consumers' preference ratings for product concepts considered worth adding to consumers'...
