Abstract
Comparison valence is an important element in comparative advertising. In this research, we investigated how comparison valence influences advertising effectiveness and explored the role of affect underlying such effects. The results of two studies consistently confirmed that a positive comparison elicited more favorable ad attitude and brand attitude than a negative comparison and consumers’ affective states accounted for their preference for the positive comparison. Moreover, we found some preliminary evidence suggesting that the preference for a positive message may be more remarkable in comparative advertisements than noncomparative advertisements. However, this proposition needs further validation in future research.
