A concept of variety seeking behavior is modeled as a stochastic brand choice model. The model yields a measure of variety seeking for each individual consumer. Panel data for 28 products are analyzed for each household and the possibility of market segmentation by variety seeking behavior is explored.
The purpose of this paper is to develop a theory of market segmentation based on consumer self-selection. The extant theory is based on the third-degree price discrimination model of Pigou, central assumptions of which are that the firm can directly address individual segments and isolate them. By using consumer self-selection, I am relaxing these assumptions. In the context of a monopolist designing a product line, I show that this relaxation has significant implications for how the products and prices are chosen and what they look like. In particular, segments may be aggregated even though there are no economies of scale. Furthermore, consumer self-selection enables us to model “cannibalization” and competition among firms.
The objective of this paper is to analyze the consumer's decision in electing to use cents-off coupons distributed by manufacturers of consumer products. Arguing that the decision to use coupons is based on the tradeoff between costs of using coupons and the savings obtained, it is shown that coupons can serve as a price discrimination device to provide a lower price to a particular segment of consumers. Based on a price theoretic model, it is shown that the users of coupons are more price elastic than nonusers of coupons and that the opportunity cost of time and other household resource variables are determinant factors in consumers' decisions. Implications derived from the model are tested using diary panel data.
