More than meets the eye: the effect of missing information on purchase evaluations

Article Abstract:

It is assumed by most information integration models that individuals making evaluations ignore attributes for which no information is available, but recent evidence indicates that individuals make inferences about missing information and that the inferences have a predictable influence on the evaluations made by individuals. In the study described, individuals were required to evaluate television purchases described by different amounts of information, with it found that the more information was missing, the less favorable was the evaluation. The results of the evaluations are reported, as well as the non-configurable effects of the relationships among multiple attributes, and the implications of the research for theory and marketing strategy are discussed.

On the use of component scores in the presence of group structure

Article Abstract:

Examination of the properties of component scores in the presence of group structure shows that the first few components extracted, typically viewed as most informative regarding total variance, do not necessarily contain the most information across group differences. A method for identifying informative components that account for across group differences is presented and illustrated. (Reprinted by permission of the publisher.)
