Item ESSAYS ON THE IMPACT OF ELECTRONIC WORD-OF-MOUTH DYNAMICS ON CONSUMER BEHAVIOR(2022) Zhao, Xindi; Trusov, Michael; Business and Management: Marketing; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Recognizing the importance of product reviews for product sales in online retail platforms, this dissertation studies the effect of electronic word-of-mouth (e-WOM) dynamics on consumer behavior, including information processing, review-reading behavior, product evaluation, purchase decision, and reviewing behavior. In the first essay, I focus on incentivized reviews, which are posted by reviewers who received economic incentives (e.g., free product) from the firm, and explore how their emergence in a reviewing system influences subsequent organic (i.e., nonincentivized) review contributions for the focal product. I find that the ratings of subsequent organic reviews decrease after the appearance of incentivized reviews and that the magnitude of this negative impact decreases over time and the ratings recover in the long run. This is because subsequent reviewers adjust their product evaluations downwards when faced with priorincentivized reviews. In the second essay, I study the effect of a prevalence phenomenon— repetition in e-WOM—on consumer behavior. I demonstrate that high repetition in e-WOM could have a negative effect on persuasion and that this negative effect could be eliminated by modifying consumers’ inferences about the cause of repetition. Furthermore, consumers’ information-seeking behaviors are also affected by the share and type of repetition. Both essays provide an understanding of the impact of e-WOM on consumers’ judgments and decisions and offer implications for firms and platforms on how to gather, manage, and display e-WOM effectively; they also provide interesting avenues for future research.Item THE INFLUENCE OF CONSUMER MOTIVATIONS ON CONSUMPTION INTENTIONS AND BEHAVIOR(2009) Espinoza, Francine; Hamilton, Rebecca W; Srivastava, Joydeep; Business and Management: Marketing; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This Dissertation comprises two essays that investigate how consumers' different motivations affect their cognitive responses and consumption behavior. Essay 1 shows that consumers' motivation to rely on their own opinion and correct their judgments for the influence of a product recommendation moderates source credibility effects on judgment certainty and behavioral intentions. Building upon earlier research showing that correction may decrease judgment certainty, we propose that, contrary to this unidirectional effect, correction has an asymmetric effect on judgment certainty and behavioral intentions, depending on the initial recommendation credibility. In a series of three studies, we provide support for the asymmetric effect of correction and show that when consumers correct for the influence of a high credibility recommendation, their judgment certainty and behavioral intentions decrease, but when they correct for the influence of a low credibility recommendation, their judgment certainty and behavioral intentions increase. Essay 2 examines the influence of consumers' motivations on product valuation and proposes that while buyers are intrinsically motivated to minimize what they are giving up, sellers are intrinsically motivated to maximize what they are getting. These differential goals lead to a discrepancy in product valuation of buyers relative to sellers. In a series of five studies, we provide support for the motivated valuation explanation for the disparity between buying and selling prices and show that when the goal pursuit of buyers and sellers is altered, buyers may be willing to buy for a higher price and sellers may be willing to buy for a lower price.
