Abstract
Despite the importance of non-price sales promotions in new-product introductions, little is known about the impact of their characteristics in different time periods and the role of moderating variables. This study examines the effects of different levels of promotion desirability and relatedness in promotion time periods and post-promotion time periods. It also examines the effects of the need for cognition variable as a possible moderator. Research results, from a between- and within-subjects experimental design, add value to the literature by providing new insights for designing promotion programs and building brands. Implications are discussed and ideas for future research are given.
