When does electronic word-of-mouth matter? A study of consumer product reviews

Online consumer product reviews, a form of electronic word-of-mouth (eWOM), have attracted increased attention from researchers. This paper examines the persuasiveness of eWOM. Drawing on regulatory focus theory, the authors propose that the consumption goals that consumers associate with the reviewed product moderate the effect of review valence on persuasiveness. Data from lab experiments and actual online retailers suggest that consumers who evaluate products associated with promotion consumption goals perceive positive reviews to be more persuasive than negative ones (i.e., a positivity bias). Conversely, consumers who evaluate products associated with prevention consumption goals perceive negative reviews to be more persuasive than positive ones (i.e., a negativity bias).     

Risking the self: the impact of self-esteem on negative word-of-mouth behavior

Negative word-of-mouth is a pervasive and persuasive force on consumers, yet little is known about the characteristics of the people who decide to share, or not to share, this information. We examine the impact of consumer trait self-esteem on tendencies to share negative word-of-mouth. Prior work has shown that consumer self-esteem moderates the likelihood of sharing positive word-of-mouth, yet extending this theory to negative word-of-mouth behavior results in conflicting predictions. This paper addresses these contradictions by adopting a two-dimensional view of self-esteem (self-liking and self-competence). We suggest that these dimensions will have opposing effects on the sharing of negative word-of-mouth. Two studies show that individuals high in self-competence are less willing to share negative word-of-mouth, whereas individuals high in self-liking are more willing to do so—results that would be disguised by treating self-esteem as a single-dimension construct.     

Examining Biased Assimilation of Brand-related Online Reviews

This paper examines the impact of pre-existing brand attitudes on consumer processing of electronic word-of-mouth (eWOM). This topic is particularly important for brands that simultaneously possess strongly pronounced proponents as well as opponents. Two experimental studies using univalent (study 1, N = 538) and mixed (study 2, N = 262) sets of online reviews find indications for biased assimilation effects of eWOM processing. Consumers perceive positive (negative) arguments in online reviews as more (less) persuasive when having a positive (negative) attitude towards the brand. Perceived persuasiveness in turn influences behavioral intentions and acts as a mediator on the relationship between attitude and behavioral intentions. We examine two moderators of this effect. When priming individuals to focus on other consumers (vs. a self-focus prime), the biased assimilation effect is weaker (study 3a, N = 131). In contrast, we show that biased assimilation becomes stronger under conditions of high (vs. low) cognitive impairment (study 3b, N = 124). Our findings contribute to the literature on the relationship between eWOM and brands and advance our understanding of potential outcomes of brand polarization.     

Understanding preferences for motion pictures

Of interest in the consumer behavior field are the drivers of experiential and aesthetic consumption. This paper considers these questions in the context of the motion picture industry. Most motion picture industry studies use secondary data to elucidate a relationship between movie attributes (genre, star power, critical reviews, distribution strategy, etc.) and box-office revenues. The study gathers primary data from 225 survey respondents in New Zealand to further understand the factors influencing the purchase decision-making process of movie-going consumers. The study uses a factor-analytic approach to map the different genres in attribute space, and to understand the drivers of choice. Overall, the results show genre, movies based on true stories, critical reviews, word-of-mouth, country of origin, pricing strategy as well as star and director power significantly impact consumers' movie choices.     

Consumer evaluations of movies on the basis of critics' judgments

Moviegoers commonly use film critics as information sources. This article proposes that consumers engage in a causal analysis of the reasons behind critics' judgments and recommendations about new movies before making their own evaluations. An experimental study was conducted where critic's style, critic's predisposition toward the film director, degree of agreement between the critic's judgment and that of other critics, reputation of the critic, reputation of the film director, and critic's judgment direction were manipulated in a mixed within‐subjects factorial design. A summary movie review was constructed for each condition of the factorial design. Viewer's movie evaluations were assessed with the use of four evaluative bipolar scales. Three of the five research hypotheses were fully supported. Consistent with the predictions of attribution theory, it was found that consumers' evaluations of a new movie are more likely to follow the judgment of a film critic when this judgment does not conform to the critic's style (H1), when the judgment is inconsistent with the critic's predisposition toward the film director (H2) and when other critics' judgments show favorable consensus (H3). The other two research hypotheses were partially supported. The impact of the film director's reputation on consumer evaluations (H5) was significant only when the movie reviews were positive, whereas the impact of the critic's reputation (H4) was significant only in the case of negative reviews. The results are interpreted within the framework of attribution theory. © 1999 John Wiley & Sons, Inc.     

The effects of word‐of‐mouth consistency on persuasiveness

Word of mouth (WOM) consistency can be readily observed in online product evaluations. Previous studies on the influence of WOM consistency on purchase intentions have showed contradictory results. In this research, we identify how stronger persuasiveness of WOM is achieved when consistency, product type, and review content work together. Study 1 shows that regarding search goods, highly consistent factual reviews are more persuasive. Study 2 shows that concerning experience goods and credence goods, highly consistent experiential reviews have greater persuasiveness. However, low WOM consistency can also achieve stronger persuasiveness under some circumstances. Moreover, in Study 3, we replicate our findings and explore the possible underlying mechanism.

Cutting Through the Online Review Jungle — Investigating Selective eWOM Processing

Consumers frequently rely on online reviews, a prominent form of electronic word-of-mouth (eWOM), before making a purchase decision. However, consumers are usually confronted with hundreds of reviews for a single product or service, as well as rich information cues on online review websites (review texts, helpfulness ratings, author information, etc.). In turn, consumers face more information cues on online review websites than they can or want to process, and are likely to proceed selectively. This paper investigates selective processing of such eWOM information cues. Results of Study 1, an exploratory study using verbal protocols, confirm that consumers display selective eWOM processing patterns and are able to articulate them. Study 2 develops and applies a measurement instrument to capture these patterns. A subsequent cluster analysis on members of a large-scale online panel (N = 2,295) indicates five prominent eWOM processing types, termed “The Efficients”, “The Meticulous”, “The Quality-Evaluators”, “The Cautious Critics”, and “The Swift Pessimists”. Insights of this research can help firms to better understand consumers' eWOM processing and improve the user-friendliness of online review websites.     

Experiential goods with network externalities effects: An empirical study of online rating system

This paper uses online users' reviews and sales information from May 2003 to March 2007 to study a new experiential product: online video game (or virtual world). The results suggest that, first of all, for a hedonic product such as an online video game, the availability of online review system could not fully transform experience attributes into search attributes. The empirical study confirms that negative word-of-mouth has more significant impact than positive reviews. The study empirically verifies that the existence of direct network externalities (i.e. a product's value increases when more consumers join the network) is crucial for a hedonic product. The size of the user base signals the quality of the game, and works like a search attribute for potential users. A large user base will reduce the negative impact from unfavorable reviews.

The dynamics of online word-of-mouth and product sales—An empirical investigation of the movie industry

There are growing interests in understanding how word-of-mouth (WOM) on the Internet is generated and how it influences consumers’ purchase decisions at retail outlets. A unique aspect of the WOM effect is the presence of a positive feedback mechanism between WOM and retail sales. We characterize the process through a dynamic simultaneous equation system, in which we separate the effect of online WOM as both a precursor to and an outcome of retail sales. We apply our approach to the movie industry, showing that both a movie's box office revenue and WOM valence significantly influence WOM volume. WOM volume in turn leads to higher box office performance. This positive feedback mechanism highlights the importance of WOM in generating and sustaining retail revenue.

Brand hate and non-repurchase intention: A service context perspective in a cross-channel setting

The purpose of this study is to investigate the brand hate phenomenon for service products in a cross-channel setting (offline/online environment). To reach this objective, structural equation modeling was employed on a sample of 265 consumers. Findings reveal that brand hate positively influences offline negative word-of-mouth (NWOM), online complaining, and non-repurchase intention. Furthermore, while offline NWOM has a positive effect on non-repurchase intention, online complaining has a negative one. Finally, a mediated path was identified, which starts from brand hate and ends with non-repurchase intention through online complaining and offline NWOM. The study provides implications for firms’ marketers and practitioners.     

Delight the experts,but never dissatisfy your customers! A multi-category study on the effects of online review source on intention to buy a new product

Online reviews are a pervasive form of electronic word-of-mouth (eWOM) that potentially accelerate—or slow down—the diffusion of recently launched services in the marketplace. While empirical research largely supports the effects of online reviews on attitudinal and behavioral outcomes, less is known about the impact the source of the review—i.e., if it comes from a peer consumer or an expert—has on the recipient. Two experiments that combine reviewer- (expert, consumer), service type- (mobile package, restaurant, car repair), consumer- (level of general innovativeness), and review-related (positive, negative) characteristics reveal a challenging interaction between the review’s source and its valence: while—compared to an established baseline—a positive expert review seems more effective in increasing the recipient's intention to purchase than a review by a peer consumer, a negative consumer review lowers the recipient's intentions to a larger extent than a negative expert review. We further find effects of the consumer's innovativeness and the service category across the experiments. Our research contributes to the topical and increasing body of empirical research on the effects of involved characteristics within online reviews across several product types.     

The Behavioral Effects of Negative Product Placements in Movies

No previous studies have examined how negative brand placements influence consumer behavior. According to this study's theoretical framework and empirical results, the effectiveness of these placements varies with the type of negativity—that is, either intrinsically or extrinsically connected to the brand. Based on the elaboration likelihood model, an intrinsically (extrinsically) negative placement will be very (barely) relevant to the viewers who, having (lacking) enough motivation, will process the information through the central (peripheral) route of persuasion. Under the central route, a careful consideration of the intrinsically negative information will discourage the viewers from consuming the brand, especially when they perceive the movie content as being realistic. Under the peripheral route, the extrinsically negative information will not be strong enough to discourage the brand users from consuming the product but will stimulate the brand nonusers to consume it, especially when these people like the movie and have a positive attitude to advertising. The hypothesized effects were confirmed in an experiment with 1103 moviegoers that viewed the film Good Bye, Lenin! under natural conditions in Santiago, Chile. To isolate the influence of two brand placements (Burger King with intrinsic negativity and Coca‐Cola with extrinsic negativity), the participants were randomly assigned to two groups, each one of which viewed the movie with only one of the two placements (the other had been removed).     

Four decades of negative word-of-mouth and negative electronic word-of-mouth: A morphological analysis

Customers voice their negative brand experiences to their family and friends in the form of negative word-of-mouth (NWOM). Web 2.0 enables the sharing of NWOM in electronic format on various social media sites, online customer review forums, and blogs, which is known as negative electronic word-of-mouth (NeWOM). Researchers need to study the spread of NWOM/NeWOM to prevent adverse consequences for companies and suggest an optimal response for its redressal. Existing literature review studies have focused on word-of-mouth (WOM) and electronic WOM (eWOM) and have considered both positive and negative WOM and eWOM concurrently. Past literature reviews have captured the breadth of the WOM domain, ignoring the depth. This research article contains a review of 282 journal papers capturing the depth of the extant literature by focusing solely on ‘negative’ WOM and eWOM (NWOM and NeWOM), and presents a broad view of the NWOM and NeWOM domains using morphological analysis (MA). This will help to conceptualize and categorize the existing state-of-the-art literature into broad dimensions and identify future research opportunities. The MA framework helps to bifurcate this literature into the following four dimensions: (i) nomenclature of NWOM and NeWOM, (ii) antecedents of NWOM/NeWOM, (iii) impacts of NWOM/NeWOM, and (iv) prevention and recovery response to NeWOM. Further dissection of these four dimensions leads to 15 sub-dimensions and 217 variants. Combinations of the 217 variants enable the identification of 550 novel future research opportunities in the area of NWOM and NeWOM.     

Do cultural orientations moderate the effect of online review features on review helpfulness? A case study of online movie reviews

The perceived helpfulness of online product reviews plays a critical role in consumers’ decisions in e-commerce. In this context, based on the literature on information processing and cultural effects, this study explored the role of review features in the perceived helpfulness of online movie reviews. A cross-cultural investigation (i.e., China cf. the United States (US)) was employed to identify high-vs. low-context cultural orientation and uncertain avoidance orientation as moderators. The results reveal that review length, timeliness, title sentiment, and emotional expressions are significant predictors of helpfulness for consumer reviews in China and the US. In addition, cultural differences between the two countries, that is, high-vs. low-context culture and uncertainty avoidance, moderated the relationships between review length, timeliness, title sentiments, and review helpfulness.     

Reviewing the reviewers: The impact of individual film critics on box office performance

Critics and their opinions or critical reviews play a major role in many markets. Marketing research on how critics impact product performance has so far examined an aggregate critic effect. An obstacle in studies examining the relationship of aggregate critical opinion and product sales is the close association between the intrinsic quality of a product and the aggregate opinion regarding the product. Our analysis parses out these two effects, allowing us to distinguish individual critics who are simply good at identifying products with popular appeal from those who act as opinion leaders and engender early product sales. The role of critics is especially prominent in the film business, in which one finds multiple expert opinions about each movie and where critics’ endorsements are used in advertising. In the context of the motion picture industry, our research investigates the impact of individual film critics on the market performance of movies, where specific key critics and reviewers may serve as market gatekeepers, and where various critics may have different types of impacts on product performance.

Online grocery shopping: the impact of shopping frequency on perceived risk

Online grocery shopping has enjoyed strong growth and it is predicted this channel will continue to grow exponentially in the coming years. While online shopping has attracted an abundance of research interest, examinations of online grocery shopping behaviour are only now emerging. Shopping online for groceries differs considerably from general online shopping due to the perishability and variability of the product, and frequency of the shopping activity. Two salient gaps underpin this research into online grocery shopping. This study responds to calls to investigate the online shoppers’ experience in the context of online purchasing frequency. Second, this study examines the mediating effect of perceived risk between trust and online repurchase intention of groceries. An online survey was employed to collect data from shoppers who were recruited from a multi-channel grocery e-retailer’s database. The online survey, comprising 16 reflective validated scale items, was sent to 555 frequent and infrequent online grocery shoppers. Results find that while customer satisfaction predicts trust for both infrequent and frequent online grocery shoppers, perceived risk fully mediates the effect of trust on repurchase intentions for infrequent online grocery shoppers. Furthermore, path analysis reveals that the developed behavioural model is variant across both groups of shoppers. Theoretically, we provide a deeper understanding of the online customer experience, while gaining insight into two shopper segments identified as being important to grocery e-retailers. For managers, this study tests an online customer behavioural model with actual purchasing behaviour and identifies the continued presence of perceived risk in grocery e-retailing, regardless of purchase frequency or experience.     

网络口碑如何促进购买意愿？——基于消费者鼓舞的被调节中介模型

网络口碑引导了消费,然而对于网络口碑影响消费者心理和行为的机制研究仍缺乏明确结论。文章以消费者鼓舞为切入点,基于SOR理论和精细处理可能性模型,构建出一个有调节的中介模型,揭示了不同口碑成分对于消费者鼓舞和购买意愿的影响作用与中介机制,以及产品类型作为边界条件形成的差异。实证检验表明,网络口碑的偏向和评分对消费者鼓舞具有正向作用,但是网络口碑数量的影响却不显著。其次,消费者鼓舞在网络口碑对消费者购买意愿的影响中起到了中介作用。同时这种中介作用受到了产品类型的调节,相对非体验性产品而言,体验性产品的网络口碑会产生更强的消费者鼓舞与购买意愿,以及更强的中介作用。最后,实验结果检验和排除了信任对于消费者鼓舞的替代性解释。文章拓展了网络口碑的研究视角,为企业有针对性地完善口碑管理提供了理论基础和实践启示。
