Bayesian methods have become widespread in marketing literature. We review the essence of the Bayesian approach and explain why it is particularly useful for marketing problems. While the appeal of the Bayesian approach has long been noted by researchers, recent developments in computational...

A common theme in marketing literature is the acquisition and retention of customers as they trade up from inexpensive introductory offerings to those of higher quality. We develop a nonhomothetic choice model to accommodate effects of advertising, professional recommendation, and other factors...

Product design, pricing policies, and promotional activities influence the primary and secondary demand for goods and services. Brand managers need to develop an understanding of the relationships between marketing mix decisions and consumer decisions of whether to purchase in the product...

Many theories of consumer behavior involve thresholds and discontinuities. In this paper, we investigate consumers' use of screening rules as part of a discrete-choice model. Alternatives that pass the screen are evaluated in a manner consistent with random utility theory; alternatives that do...

The ability to demonstrate the impact of marketing action on firm financial performance is crucial for evaluating, justifying, and optimizing the expenditure of a firm's marketing resources. This presents itself as a formidable task when one considers both the variety and potential influence of...

Rotating indifference curves are used to induce an income effect that favors superior brands at the expense of inferior brands in a discrete choice model. When calibrated on scanner panel data, the model yields an objective measure of brand quality which is related to the rate of rotation. The...

An important aspect of marketing practice is the targeting of consumer segments for differential promotional activity. The premise of this activity is that there exist distinct segments of homogeneous consumers who can be identified by readily available demographic information. The increased...

Consumers are often observed to purchase more than one variety of a product on a given shopping trip. The simultaneous demand for varieties is observed not only for packaged goods such as yogurt or soft drinks, but in many other product categories such as movies, music compact disks, and...

The use of adaptive designs in conjoint analysis has been shown to lead to an endogeneity bias in part-worth estimates using sampling experiments. In this paper, we re-examine the endogeneity issue in light of the likelihood principle. The likelihood principle asserts that all relevant...

A one-to-one map between a specific demand structure and a restricted cross-elasticity matrix is developed and tested using a random utility model. The resulting demand structure can be used to evaluate a firm's ability to differentiate its products, and can help determine if demand is...
