Preference consistency implies that people have learned their willingness to trade off attributes. We argue that this is not necessarily the case. Instead, we show that when preferences are learned in context (e.g., through repeated choices made from a trinary choice set that includes an...

During the completion of a conjoint task, fatigue, boredom, or task simplification strategies and learning effects may cause unobserved changes in individual consumer preferences. We propose a hierarchical Bayesian dynamic switching model that we call Change Point Heterogeneity model (CPHM) to...

Marketers often analyze multinomial choice from a set of branded products to learn about demand. Given a set of brands to study, we analyze three reasons why choices from strict subsets of the brands can contain more statistical information about demand than choices from all the brands in the...

Failures in the use of self-service technology are not only a source of dissatisfaction; often, they also trigger negative emotions of anger and helplessness. Drawing on the appraisal theories of emotion, I argue that these emotions have distinct effects on customers' post-purchase reactions...

Continuous models of respondent heterogeneity assume the existence of a response function where variables of interest are continuously related to explanatory variables. In many situations this assumption may not be true. In this paper we propose an approach of modeling respondent heterogeneity...

Either empty inventories or empty shelves can cause stock-outs in retailing. Both can occur independently from each other, entail different kinds of damages and thus call for different counter measures. As such a counter measure, this paper presents a method to detect empty shelves through...
