We provide an in-depth theoretical discussion about the differences between individual-
specific latent constructs (representing attitudes, for example, but also other characteristics …

Random utility models are typically based on the assumptions that individuals exhibit
compensatory behaviour and that their choice sets are pre-specified. These assumptions …

Existing models of disaggregate decision-making assume that preferences, as indicated by
taste parameters and choice sets, are characteristics of the decision-maker that are …

The study of respondent heterogeneity is one of the main areas of research in the field of
choice modelling. The general emphasis is on variations across respondents in relative …

Individuals when faced with choices amongst a number of alternatives often adopt a variety
of processing rules, ranging from simple linear to complex non-linear treatment of each …

Latent class models are a convenient and intuitive way to introduce taste heterogeneity in
discrete choice models by relating attributes of the decision makers with unobserved …

In this paper we formulate a discrete choice model that incorporates thresholds in the
perception of changes in attribute values. The model considers multiple options and allows …

Values lie at the heart of an individual's belief system, serving as prototypes from which
attitudes and behaviors are subsequently manufactured. Attitudes and behaviors may …

Discrete choice models and, more recently, latent variable models have been widely applied
to problems in transportation, economics, geography, marketing, public policy and …

This paper investigates alternative methods to account for preference heterogeneity in
choice experiments. Heterogeneity can be explained by assuming its influence to impact the …
