Income is a key variable in many choice models. It is also one of the most salient examples of a variable affected by data problems. Issues with income arise as measurement errors in categorically captured income, correlation between stated income and unobserved variables, systematic over- or...

Best-Worst Scaling (BWS) modeling is widely used for finding probabilities of choice among multiple items. The paper considers how to apply BWS data to another problem – of finding the items׳ cannibalization and synergy. For a product of primary interest, we estimate its probability to be...

Discrete choice (DC) models are often used to describe consumer behaviour at a disaggregate level. At this level, a choice decision is defined in terms of a set of alternatives representing different ‘varieties’ of a particular product differentiated mainly by their quality attributes rather...

The notion of Value of Time (VoT) is a cornerstone of discrete choice based economic appraisal in transportation. Its derivation and interpretation in the context of Random Utility Maximisation (RUM) models with linear-additive utility functions is straightforward and well known. The choice...

The concept of a consideration set has become a central concept in the study of consumer behavior. This paper shows that the common practice of estimating models using only the set of alternatives deemed to be in the set considered by a consumer will usually result in estimated parameters that...

Models of consumer learning and inventory behavior have both proven to be valuable for explaining consumer choice dynamics. In their pure form these models assume consumers solve complex dynamic programming (DP) problems to determine optimal choices. For this reason, these models are best viewed...

We propose and test a choice model based on the notion that the category an alternative is perceived to fall into determines the attribute importance weights used to evaluate that alternative. For example, space is more important than fuel economy for an SUV, but the opposite is true for a...

The aim of this paper is to present and test a crucial building block for a regret minimization based choice set formation model, in that it presents a regret based benefit measure for the value associated with adding an alternative to one׳s choice set. By doing so, the paper contributes to...

We present a test of antecedent volition under conditions of varying choice complexity. Using a stated preference design, decision makers make hypothetical transport choices under three decision scenarios. The choices are made under conditions of three, five, and seven alternatives per choice...
