The purpose of this paper is to explore different types of source expertise and how they influence perceived message quality. Consumers face the challenge to identify valuable online reviews. Source expertise as a signal of message quality can be displayed differently, depending on website layout, operator and review author.

Two scenario-based experiments were conducted questioning 135 and 275 participants. They investigate the effect of different types of expert reviewers on perceived message quality and also examine the interplay of source expertise and source trustworthiness.

The findings reveal that the different types of expert reviewers differ in perceived expertise and their impact on perceived message quality. Claims of expertise induce the highest perceived expertise compared to the other expert types and non-experts, but are perceived as less trustworthy.

Future research should examine the influence of the expert types across different product and service categories and could also include moderating influences that reflect how consumers process expert cues differently.

Cues that signal high expertise and high trustworthiness are likely to deliver the most valuable online reviews. This should be incorporated in the website's layout to help consumers find valuable information.

The approach of this research is novel in that it undertakes comparisons between three types of expert cues and non-experts. It also addresses the interplay of source expertise and trustworthiness and examines the effect on message quality.

In the current war for talent employers are concerned about the idea that the best employees are more likely to leave the organization for another employer (i.e. the management paradox). This study tests this management paradox. The purpose of this paper is to advance our understandings of how employees’ occupational expertise is associated with job search intensity, through its assumed relationships with perceived internal and external employability in the internal and the external labor market. The authors thereby tested the research model across three different age groups (young, middle-aged, and senior employees).

The authors conducted a survey among 2,137 professional workers and applied multi-group structural equation modeling.

Perceived internal employability negatively mediated the relationship between occupational expertise and job search intensity, whilst there was a positive mediational effect of perceived external employability. Age had a moderating effect on the association between perceived internal employability and job search intensity.

The findings contribute to the scholarly literature on the management paradox, and the empirical work on employability and age.

Organizations can recoup their investments in expert workers’ employability and enhance their retention by providing opportunities for internal career development.

This study is original by including both internal and external employability. By doing so, the authors thereby shedding new light on how occupational expertise might explain job search and how this relationship differs depending on employee age, thereby using a large sample of respondents.

The purpose of this study is to develop, assess, and provide uses for a measure of perceived enterprise resource planning (ERP) systems expertise for financial statement auditors. ERP systems are the dominant system used by the public company clients of audit firms. In such settings, the Theory of Planned Behavior suggests that auditor perceptions of their own ERP systems expertise should influence their perceived behavioral control and, in turn, explain auditor behavior.

A five‐item measure of perceived ERP systems expertise is developed from a review of audit expertise studies and the Theory of Planned Behavior.

An assessment of the measure shows that it possesses a high level of reliability and construct validity (i.e. convergent and discriminant validity). Factor analysis results indicate that all five items satisfactorily load on one factor. The results also suggest that auditors' perceptions of ERP systems expertise are not simply a by‐product of general audit experience (AUDEXP).

Discusses possible future uses of the measure, including whether the measure explains auditor control testing performance and the customization of the measure for IT audit specialists and internal auditors.

This study's measure should provide researchers with a tool to examine how auditor self‐perceptions of ERP systems expertise can affect auditor behavior and the quality of contemporary audit services.

This study investigates how individuals' self-awareness (specifically, private and public self-awareness) and environment-awareness (perceived expertise, similarity and familiarity) shape herd behavior, encompassing discounting one’s information and imitating others. Drawing from latent state-trait theory, this research aims to discern the impact of these factors on purchase intention and behavior.

Longitudinal data from 231 users in Xiaohongshu, China’s leading social commerce platform, were collected to test the proposed model and hypotheses.

The findings from this study show that private self-awareness negatively influences discounting one’s own information and imitating others. Public self-awareness positively affects imitating others, while it does not affect discounting one’s own information. Perceived expertise diminishes discounting one’s own information but does not significantly affect imitating others. Perceived similarity and perceived familiarity are positively related to discounting one’s own information and imitating others. The results confirm different interaction effects between self-awareness and environment-awareness on herd behavior.

First, this contributes back to the latent state-trait theory by expanding the applicability of this theory to explain the phenomenon of herd behavior. Second, this study takes an important step toward theoretical advancement in the extant literature by qualifying that both self- and environment-awareness should be considered to trigger additional effects on herd behavior. Third, this study provides a more enlightened understanding of herd behavior by highlighting the significance of considering the interplay between self- and environment-awareness on herd behavior. Finally, this study also empirically confirms the validity of classifying self-awareness into private and public aspects.

This study aims to examine how and when trainers' muscle mass impacts service purchase of personal fitness training, drawing upon signaling theory. Specifically, the authors investigated (1) the mediating role of perceived competence in the relationship between trainers' muscle mass (highly vs moderately muscular) and customers' service registration intention and (2) the moderating role of customer expertise in this mediating mechanism.

The authors conceptualized trainers' muscle mass, developed its experimental stimuli and validated them through the two pretests (total n = 387). Using the validated stimuli, the authors conducted the two experiments (total n = 802). In both experiments, the authors recruited participants via MTurk using the convenience sampling method and employed a single-factor between-subject design based on random assignment.

Findings supported the authors’ proporsed model. Consumers perceived highly (vs moderately) muscular trainers as more competent, which in turn engendered greater service registration intention. This effect emerged for expert consumers but not for novice consumers.

This study is one of the first attempts to empirically test the influence of trainers' muscle mass on consumer acquisition in the context of personal fitness training. It also expands the sport marketing literature to the consumer psychology and behavior fields addressing the characteristics of sport-service providers. The findings also provide fitness organizations with managerial insights into how to effectively leverage trainers' physical appearance as a marketing tool.

The purpose of this paper is to investigate the impact of buyer-seller interpersonal interactions on the purchase intention of buyers, incorporating swift guanxi as a mediator.

Based on survey data obtained from 336 Taobao Live users, PLS techniques were used to test hypotheses.

Swift guanxi exists in buyer-seller interactions and matters, as it drives buyers' purchase intention in live stream shopping. Perceived expertise, perceived similarity and perceived likeability are found to be the three essential interpersonal interaction factors promoting the formation of swift guanxi. Perceived familiarity is also found to be significant but to a lesser extent. In addition, all these interpersonal interaction factors are found to significantly affect purchase intention through the mediation of swift guanxi.

Swift guanxi has been less explored in live stream shopping. This study takes the lead in empirically examining the mediating role of swift guanxi in the relationship between interpersonal interaction factors and purchase intention and offers a description of key buyer-seller interpersonal interaction factors (perceived expertise, perceived similarity and perceived likeability), thereby helping to extend the swift guanxi literature in social commerce.

The purpose of this study is to determine the influence of celebrity credibility (trustworthiness, attractiveness and expertise) on risk perception and buying intention of Indian fast moving consumer goods (FMCG) consumers.

The present study adopted the survey method to know the influence of celebrity credibility dimensions on the perceived risk and purchase intentions of Indian FMCG consumers. This study has performed a survey on 250 respondents using the self-administered questionnaire consisting of 18 measurement scales.

The major findings of this study indicate celebrity trust and celebrity expertise are the most important dimensions of celebrity to influence the risk perceptions of Indian FMCG consumers. The risk perceptions positively influence the purchase intentions of Indian FMCG consumers.

This study was limited to the Indian context, but theoretical contributions in terms of justifying the relationship linking variables, which might affect success, as well as the failure of celebrity endorsements.

The research findings can assist the practitioners in selecting the right celebrity endorser as a spokesperson for promoting Indian FMCG brands based on three dimensions of celebrity credibility (trust, expertise and attractiveness).

The study has proposed and tested the new theoretical model considering the celebrity trust, celebrity expertise and celebrity attractiveness as the affective responses from the buyers of FMCG. Perceived risk is mainly cognitive responses influenced through celebrity credible sources. The study attempted to investigate the impact of both affective and cognitive responses on the purchase intentions of Indian FMCG consumers.

Interpersonal interaction can influence consumers’ purchase intention in social commerce (s-commerce). This paper aims to identify interpersonal interaction factors as well as the mediating effect of relationship quality between interpersonal interaction factors and consumers’ purchase intention in s-commerce.

This study explores new dimensions of interpersonal interaction in s-commerce by integrating interaction between consumers and online vendors and that between consumers and online recommenders in s-commerce. An online questionnaire was used to collect the data, and partial least squares structural equation modeling (PLS-SEM) was employed for data analysis.

The results indicate that interpersonal interaction factors of both online vendors and online recommenders positively affect swift guanxi and initial trust between consumers and online vendors. Swift guanxi and initial trust positively affect consumers’ purchase intention. Initial trust partially mediates between interpersonal interaction factors and purchase intention while swift guanxi does not mediate between perceived similarity of online recommenders and purchase intention.

The findings can be used to guide vendors in s-commerce platforms to make good use of platform features to improve interpersonal interaction. Meanwhile, s-commerce platforms should be enhanced with efficient interaction tools to help cultivate relationship quality between consumers and online vendors.

This study combines social exchange theory, trust transfer theory and relationship quality theory to investigate the factors that influence swift guanxi and initial trust between consumers and online vendors, which extends the study of interpersonal interaction and enriches the dimensions of relationship quality in the context of s-commerce.

Based on the involvement and customer-delivered value theories, this paper proposes a comprehensive framework with which to examine the relationships between food traceability system, consumer perceived value and purchase intention. The study also investigates the moderating role of consumer expertise in the relationship between food traceability system and perceived value.

Survey approach is the primary data collection tool, through which a total of 238 useable responses were obtained. Structural equation modelling is employed to examine the hypothesized relationships among all variables.

The findings show that the information quality, perceived reliability and product diagnosticity of food traceability system affect consumer perceived value, and the perceived value and purchase intention are positively associated, while consumer expertise acts as a moderator on the relationship between food traceability system and consumer perceived value.

This study sheds light on how consumer perceived value of food traceability system can enhance their intention to purchase traceable food. It contributes to the theory of customer-delivered value and involvement as well as traceable product marketing strategies. From a managerial perspective, guidelines are provided for traceable food producers and marketers to implement reasonable strategies to attract consumers to purchase and promote the sustainable development of food industry.

This study aim to attempt to conceptualize agency in a hospitality setting and examine the psychological effects of agency-related visual cues on user perception and intention to use to understand the role of agency in the digitalization of hotel services.

After developing demo videos of an express check-out application, two experiments were conducted to examine the effects of using an avatar and explain the psychological mechanism of how attributes of an avatar increase intention to use.

Study 1 found that the presence of an avatar had a positive influence on intention to use. Study 2 retested the findings of Study 1 and illustrated the psychological mechanism of how two attributes of an avatar (social position and gender) influenced perceived expertise and intention to use. A significant interaction effect between social position and gender was found on perceived expertise. Perceived expertise also mediated the effect of an avatar on intention to use in the male avatar conditions.

As the first attempt to investigate the role of avatars in human–computer interaction in a hotel setting, this study will serve as an example in testing the effects of agency-related technical features on user experience and behavioral intention, possibly broadening the current research scope of hospitality and tourism. This study also provides a useful guideline to develop and design a successful interface of digitalized hotel services.
