The effects of product knowledge on the evaluation of warranteed brands

This study explores the effects of consumer knowledge on respondents' evaluations of both known and unknown brands that include either a 2-year or a 20-year warranty. Both experts and nonexperts evaluated warranty as more important than brand name in their product quality decision. Warranty length was positively correlated with product quality perceptions for both known and unknown brands. With the unknown brand, nonexperts perceived significant improvement in product quality when the warranty length was increased from 2 to 20 years. For the known brand, nonexperts perceived little difference in quality for the two warranty lengths. Experts indicated no significant differences in perceived quality, given the four brand/warranty-length conditions. The results indicate that warranty length is most heavily weighted as a cue to product quality when consumers are not highly knowledgeable, and the brand name is not well known. © 1996 John Wiley & Sons, Inc.
