Conjoint analysis as a commercial method has been available for more than 20 years (Green, Wind and Jain 1972). Ten years ago, 1987, at a Sawtooth conference, I raised the question of how conjoint could work so well, given obvious differences between the task and market choice. I proposed that conjoint works primarily because the simplification in a conjoint task mirrors the simplification in t...

Traditional models of conjoint measurement look for an additive representation of transitive preferences. They have been generalized in two directions. Nontransitive additive conjoint measurement models allow for nontransitive preferences while retaining the additivity feature of traditional models. Decomposable conjoint measurement models are transitive but replace additivity by a mere decompo...

This paper presents a self-contained introduction to a general conjoint measurement framework for the analysis of nontransitive and/or incomplete binary relations on product sets. It is based on the use of several kinds of marginal traces on coordinates induced by the binary relation. This framework leads to defining three general families of models depending on the kind of trace that they use....

Research on conjoint analysis/preference aggregation/social choice aggregation is performed by more than forty years by various communities. However, many proposed mathematical models understand preferences as irreflexive, transitive and statical relations while there is human psychology research work questioning these properties as being not enough motivated. This works propose to position the...

At the present time, there is one set of techniques for proving representation theorems for finite measurement structures an another set for infinite structures. Techniques for finite structures were developed in Scott (1964) and basically consist of solving finite sets of inequalities; techniques for infinite structures in one way or another resemble those used in Holder (1901) an d consist of...

This paper investigates the adequacy of the hierarchical Bayes (HB) model for rankbased conjoint data. While recent research has demonstrated the robustness of the HB model compared to traditional estimation methods for rank based conjoint models, we conduct an indepth analysis of the underlying reasons of these findings. Hereby we investigate the fundamental assumptions of rank based conjoint ...

Consumer reservation price is a key concept in marketing and economics. Theoretically, this concept has been instrumental in studying consumer purchase decisions, competitive pricing strategies, and welfare economics. Managerially, knowledge of consumer reservation prices is critical for implementing many pricing tactics such as bundling, target promotions, nonlinear pricing, and one-to-one pri...
