The influence of pre-decisional constraints on information search and consideration set formation in new automobile purchases

We propose that the manner in which a purchase decision is initiated has an important influence on subsequent product evaluation and choice. Specifically, we propose that the problem recognition "event" and the consequent retrieval of pre-decisional constraints from memory significantly influence the ensuing processes of external information search and consideration set formation. Several hypotheses are developed to model these interrelationships. The data were collected from a national probability sample of new automobile buyers. Log-linear, logistic regression and linear regression analyses were used to test the hypotheses. The results suggest that the type of pre-decisional constraints that are activated as a consequence of the problem recognition event significantly influences the "route" consumers follow through the remainder of the purchase process. The findings have important theoretical and practical implications for understanding the consumer decision process for consumer durables. (C) 2002 Elsevier Science B.V. All rights reserved.
