A range of variables have been incorporated into
brand choice models in an attempt to tease out
the factors responsible for different consumer
responses. The ‘ purchase model ’ developed by
Krishnamurthi et al . 13 focuses upon consumer
loyalty to analyse different response to loss and
gain. Simonson and Winer 14 explain differences in
the brand choice process in terms of the quantity
of the product purchased. The use of
demographic and psychographic variables has
also been useful to estimate the preference
of consumers for distributors ’ brands and
promotions. 15 Taking this and other research
as a starting point, this paper focuses on the
effect of two segmentation variables on the
process of brand choice: loyalty and consumption
level.
