This study aims to explore the use of consumer-generated online product reviews as a source of brand associations in a sport setting.

A total of 800 reviews were collected and categorized into 13 brand association dimensions derived from previous literature. Reviews were further categorized into three valence types (i.e. positive, negative and neutral) via a correspondence analysis.

A correspondence analysis revealed that positive product reviews were highly linked to performance and product-related attributes, while negative reviews were related to conformance associations. Additionally, the results showed that product-related (90.8%) attributes, experiential benefits (89.1%) and functional benefits (86.6%) were the most frequently communicated brand associations. The findings of this study underline the credibility of assessing brand associations from the consumers’ experience, through online consumer reviews.

The findings of the current investigation contribute to existing knowledge by examining consumer-based brand equity (CBBE) in an online setting. Previous, CBBE literature suggests that brand associations are held in the minds of the brand's consumers. To date, however, few studies have examined brand associations generated by consumers and instead have relied upon brand association dimensions developed by the researcher as opposed to the consumer (Ross et al., 2006). This, study however, utilized online sport product reviews as a source of consumer derived brand associations, and, therefore, will further the knowledge as to how brand associations are identified and measured.

The objective of this study is to examine the effects of pictures (consumer pictures vs. product pictures vs. no pictures) in online consumer reviews on product evaluation and to determine the mechanism and boundary conditions behind such effects.

The research consisted of three laboratory experiments.

The results showed that consumer pictures led to the most favorable product evaluation. Study 1 showed that persuasive effect was the mechanism behind the main effect. Study 2 showed that for problem-solving products, consumer pictures increased product evaluation significantly; for enhancing products, there was no significant difference of product evaluation among consumer pictures, product pictures and no picture. The results of Study 3 showed that for the unfamiliar brand, consumer pictures significantly enhanced product evaluation; for the highly familiar brand, there was no significant difference among consumer pictures, product pictures and no picture. The present research used persuasive effects to examine the mechanism behind the interaction effects.

The study provides managerial implications for online store owners about how to manage pictures in online reviews.

This study supplements the literature on online consumer reviews and enriches the study of effects of pictures.

The conclusions of studies on the factors correlated with the perceived usefulness of online reviews are inconsistent due to differences in research perspectives, research objects, research methods and data types. This study conducted a meta-analysis to verify a proposed model of perceived usefulness to obtain general conclusions.

A meta-analysis was conducted to study the factors correlated with the perceived usefulness of online reviews based on 51 studies.

The results indicate that, with the exception of negative reviews, the order of relevance for the perceived usefulness of online reviews is as follows: the trust tendency of review readers, review replies, review depth, review pictures, reviewer trustworthiness, positive reviews, reviewer expertise, review time and reviewer information disclosure. Perceived usefulness was significantly positively correlated with purchase intention. Review time, positive reviews and negative reviews were also more significantly correlated with perceived usefulness for search products than for experiential products. Review depth, reviewer trustworthiness, reviewer expertise and purchase intention had greater positive correlations with perceived usefulness for experiential products than for search products.

This study proposes an extended information adoption model based on argument quality and source credibility. The model includes personal factors such as the trust tendency of review readers, constructs a theoretical model of the factors correlated with the perceived usefulness of online reviews and considers the moderating effects of product type.

The purpose of this paper is to propose a model to test whether the combined effects of valence and objectivity/subjectivity of online review have an effect on consumer judgment and whether e-WOM platforms have a moderating effect.

In total, 480 respondents participated in online experiments with a four (positive+objective, positive+subjective, negative+objective, and negative+subjective online review) by two (marketer-generated vs consumer-generated brand community web sites) between subject design.

The experiment showed that: an objective negative online review was rated higher in terms of message usefulness compared to the other types of online reviews; positive reviews, whether they are objective or subjective, were rated higher in terms of attitudes toward and intention to purchase the reviewed product, and the effects of online reviews moderated by e-WOM platforms on consumer judgment were supported.

The present study, based on an established theoretical foundation, will help the research community to gain a deeper understanding of the combined effects of online review valence and attributes on consumer judgment and whether user-generated web community is better for consumers to consult product experience.

The findings of this study can provide interested firms with useful strategies and tactics to enhance users’ acceptance of online reviews in terms of who operates the web sites.

With increasing use of consumers’ online reviews, the present study proposed and tested a comprehensive research model integrating both the valence and objectivity/subjectivity of online review, which has rarely been addressed in previous research.

This paper aims to investigate the impacts of uncertain online reviews on product prices and profits of two competitive retailers.

First, the authors develop a game-theoretical model to determine the optimal product prices and profits considering uncertain online reviews. Afterwards, to examine the effects of the uncertain online reviews, they compare the equilibrium solutions with those of the game-theoretical models of deterministic online reviews and no online reviews, respectively.

Uncertain online reviews play a significant role in product price optimization and profit maximization. In the quality-dominates-fit case, both retailers will lower their product prices in response to the uncertain online reviews. And the uncertain online reviews would hurt the two retailers. Conversely, in the fit-dominates-quality case, the presence of uncertain online reviews will encourage both retailers to raise their product prices. And the two retailers can still benefit from the online reviews. With the increase in consumer uncertainty about online reviews, both retailers might raise their product prices, thus generating higher profits.

Managerially, the results indicate that in the quality-dominates-fit case, when consumers are uncertain about online reviews, it might be better for retailers to abandon the online review system; however, in the fit-dominates-quality case, both retailers could still benefit from the uncertain online reviews through product price optimization. Therefore, the presence of an online review system could be beneficial.

This paper develops a game-theoretical model to help competitive retailers optimize their price strategies and achieve profit maximization considering uncertain online reviews.

This paper aims to explore the effect on consumer responses of firms’ manipulating online reviews based on review valence (positive vs negative) and the relationship between consumer trust and purchase intentions.

This study was designed as an experimental study using a scenario method, and data were randomly collected from 2,080 online shoppers in the USA.

Findings reveal that the unfair business practice of manipulating online postings considerably undermined consumer trust toward online reviews. Consumer trust in reviews thus seems to be a critical predictor of purchase intentions, which was strengthened even when respondents knew that online reviews were manipulated.

Companies may thus need to focus on maintaining transparency and truthfulness in online consumer reviews rather than artificially improving ratings scores or feedback levels.

This study was the first attempt to provide empirical supports that the level of consumer trust in online reviews significantly decreased after consumers were informed that the review content had been manipulated by a company in both the positive and negative conditions. These results also support previous research articulating the negativity effect.

Against the background of industrialisation and modernisation of agriculture, food production issues and environmental hazards have become more and more obvious and consumers are increasingly concerned about food safety and health, which is strengthening demand for organic food. E-commerce provides a new channel for sales. Research on consumer trust in online organic food sales is the basis of network marketing. The paper aims to discuss these issues.

A laboratory experiment was used to empirically test the effects of media richness on consumers’ trust and the moderating effect of online review length. A 2×2 factorial design (i.e. two types of online product presentation formats (between-subject)×two levels of online review lengths (between-subject)) was used.

Media richness has a significant positive effect on consumers’ trust and that this effect is moderated by online review length. Meanwhile, perceived risk conveys the interaction effect of the media richness of online product presentation and online review length to trust.

E-commerce websites should aim to promote organic food by using a variety of online product presentation formats and by presenting high quality online reviews in order to reduce consumers’ perceived risk and improve their degree of trust when buying online.

This paper provides a new insight into consumers’ attitude of buying organic food online. The results of the research could provide proposals for promoting organic food sales online.

Online reviews have been indicated to play an important role in consumers’ decision-making process, as supported by numerous studies. However, none of them has considered the neighborhood effect of online reviews. The purpose of this paper is to analyze the impact of neighbor store’s reviews on central store’s, along with the moderating effects of store density and product similarity.

Using data from dianping.com, this study conducts economic analysis accounting for endogeneity.

The results show that the neighbor store’s reviews exert a negative impact on that of central stores. Nevertheless, the relationship is moderated by store density and product similarity, such that the negative effect is stronger if there are a lot of stores around the central store, or if the neighbor store and central store provide similar products.

This study is the first to investigate the neighborhood effect of online reviews.

To influence consumer perceptions, firms often manipulate online product reviews on their own websites or third-party forums by anonymously adding positive reviews, deleting unfavorable reviews or offering rewards to encourage favorable reviews. This study aims to investigate consumer perceptions of online review deceptions and how these perceptions influence their subsequent purchase behavior. In particular, consumers’ awareness, suspicion and detection are studied and specific manipulation tactics are evaluated.

Both qualitative and quantitative studies are relied upon to understand consumer perceptions of online review deceptions. In-depth interviews with 16 experienced online shoppers were conducted to collect the illustrative accounts concerning consumer awareness of online review deceptions, their suspicion, detection and evaluation of different manipulation tactics. A survey of 199 consumers was then followed to validate and corroborate the findings from the qualitative study and generalize the interview results onto the general public.

The results from in-depth interviews suggest that consumers take a negative view toward online review deceptions, but the degree of negativity varies across different manipulation tactics. Moreover, different types of manipulations vary in terms of perceived deceptiveness, ease of detection and unethicality, as well as their effect on consumer purchase intention and perceived helpfulness of online product reviews. The findings from the survey further confirmed the qualitative findings.

The findings have a number of meaningful managerial implications for industry associations and policymakers on whether and how to regulate online review deceptions.

This study applies and extends information manipulation theory and deception detection literature to an online context to increase the richness of the relevant theories. It is among the first to empirically investigate online review deceptions from a consumer’s perspective, as opposed to a firm’s perspective as previous studies have done.

Valence and volume of online reviews are generally considered to influence sales positively. However, existing findings regarding the relative influence of these two components have been inconclusive. This paper aims to explain some of these inconsistencies by examining the moderating role of regulatory focus (both as a chronic disposition and as a situational focus induced by the product category) in the relationship between online review volume/valence and consumers purchase decisions.

Two studies were conducted. Study 1 used a 2 (Volume: high/ low) * 3 (Valence: high/medium/low) within-subject experimental design. Study 2 analyzed real-world data from Amazon.com. Logistic and panel regression analyses were used to test the research hypotheses.

The studies confirmed the hypothesized effect of regulatory focus on online review valence and volume effects. Specifically, Study 1 showed that online review valence was more impactful for consumers with a promotion focus than for consumers with a prevention focus. The opposite was true for online review volume effects, where consumers with a prevention focus were influenced more by volume in their decision-making compared to consumers with a promotion focus. Study 2 showed that the pattern of results we found in Study 1 also applied to situational regulatory focus induced by the product category. The effect of review volume on sales rank was stronger for prevention-oriented products, whereas the effect of valence was stronger for promotion-oriented products.

In Study 1, one product category was involved in the study (Digital camera). Involving more different product categories will add reliability to the results of current research. Also, it can offer external validity to current research results. In Study 2, there was no exact measurement for sales, as Amazon.com does not share that kind of information. Instead, Sales Rank was used as a proxy variable. Future research could look into the websites that offer access to the exact sales information.

The current research findings suggest the need for companies to adapt their consumer review management strategy to the regulatory orientation of their target market and products. When a promotion-focused mindset is targeted, strategies for increasing the favorability of product reviews should be used, in contrast, tactics for increasing the quantity of reviews may be more suitable when a prevention-focused mindset is involved.

To the best of the authors' knowledge, this research is the first to investigate the interaction between regulatory focus of consumers and products and online review components.
