When modeling demand for differentiated products, it is vital to adequately capture
consumer taste heterogeneity, But there is no clearly preferred approach. Here, we compare …

The mixed or heterogeneous multinomial logit (MIXL) model has become popular in a
number of fields, especially marketing, health economics, and industrial organization. In …

There is growing interest in establishing a mechanism to account for scale heterogeneity
across individuals (essentially the variance of a variance term or the standard deviation of …

The treatment of heterogeneity across individual decision makers is one of the key topics of
research in choice modelling, as evidenced by many of the chapters in this book. While, in …

Discrete choice models of aggregate demand, such as the random coefficients logit, can
handle large differentiated products categories parsimoniously while still providing flexible …

Currently, there is an important debate about the relative merits of models with discrete and
continuous representations of consumer heterogeneity. In a recent JMR study,; hereafter …

THIS paper presents a simple approach to describe the demand of a population of
heterogeneous consumers for a set of differentiated goods. The demand system used is the …

Consumer heterogeneity is fundamental to the marketing concept, providing the basis for
market segmentation, targeting and positioning, as well as micro-marketing. Substantial …

Most applications of discrete choice models in transportation now utilise a random
coefficient specification, such as mixed logit, to represent taste heterogeneity. However, little …

A growing body of empirical literature uses structurally-derived economic models to study
the nature of competition and to measure explicitly the economic impact of strategic policies …
