A popular procedure for benefit segmentation based on conjoint experiments has been to estimate individual-level port worths and then form nonoverlapping clusters of consumers with similar estimates. Rather than using these estimates as the criteria for clustering, the least squares procedure...

This paper extends past research on new product diffusion by taking a long-term view of the diffusion process for several consumer durables. Specifically, we investigate the role of price and adoption influence processes within the product diffusion framework by assessing the relative...

A variant of Banker and Morey's (1986) DEA model for controllable ordinal outputs. As opposed to the original model, this version allows the comparison of a Decision Making Unit (DMU) to other DMU's operating at equal or higher levels of the ordinal outputs

This study presents a general methodology capable of addressing a number of fundamental questions in consumer policy. Are consumers paying more than the minimum price for a given bundle of attributes? If so, what brands cost more than the consumer needs to pay? What would be the degree of...

The authors demonstrate how item response theory can be applied for cost effective measurement of consumer attitudes with multi-item scales. The measurement technique they discuss and illustrate is tailored to each respondent so that each is asked only the scale items most informative of his or...

Recent advances in data gathering through checkout scanners have pro­duced vast amounts of data on the actual behavior of consumers in the mar­ketplace, creating new opportunities for managers and researchers to under­ stand competition and consumers' response to the marketing mix. Previous...

The authors present a tailored interviewing procedure for life-style segmentation. The procedure assumes that a life-style measurement instrument has been designed. A classification of a sample of consumers into life-style segments is obtained using a latent-class model. With these segments, the...

One of the main problems in assessing the relative efficiency of multiple retail outlets is the fact that customers are an essential component of the "production process" in retailing. Hence, the efficiency of a particular retail store depends both on the seller's and the buyers' efficiency....

Household basket data contain important information about the structure of brand preferences both within and across product categories. This research exploits the information in long-run basket summary data to segment consumers with respect to brand preferences. The approach provides insights...

Conjoint choice designs are frequently applied in practice, and often a base alternative is added to the design. When such a 'no-choice' base alternative is present in conjoint choice experiments a constant term should be added to the design ('X'-) matrix with attribute dummies when effects type...
