How third‐party certification programs relate to consumer trust in online transactions: An exploratory study

Consumer fears about Internet security and ordering over the Internet can influence online buying behavior, and these fears may be exacerbated by increasing attention to identity theft. A key strategy to increase consumer trust in ordering has been participation in third‐party certification programs. This study presents a model describing the relationship between third‐party identifying logos, trust transfer, and trust buildup and tests the model with data collected by an online survey. The results support hypotheses that perceptions of third‐party logos are related to intensity of seal exposure, importance of trust factors in online shopping, and disposition toward third‐party certification. Also, such perceptions and the current level of consumer trust in general in online shopping are positively related to transfer of trust from certification to online e‐marketers. Prior research found that validating logos does not increase transfer of trust; a post‐hoc analysis revealed that this finding is dependent on type of logo. The findings indicate that Web site certification can reassure potential customers and increase the probability of purchase. © 2008 Wiley Periodicals, Inc.     

The effect of buyer feedback scores on internet auction prices

One of the major roles of Internet intermediaries is to help build trust between buyers and sellers for efficient and safe transactions. The buyer feedback system started in online auctions as one of the trust‐building mechanisms on the Internet. As the buyer feedback system is becoming a standard trust‐building mechanism in other e‐commerce sites as well as in online auction, there is an increasing interest about the impact of the buyer feedback system. On the top of recent studies investigating the effects of buyer feedback scores on auction prices, we provide empirical validations using more sophisticated methods. In this study, we tested the relationship between buyer feedback scores and bidding prices using an empirical data set from a leading consumer‐to‐consumer (C2C) Internet auction site. Data analysis results show a strong empirical validation of previous studies. Negative feedback is a significant price discount factor in the final auction price on the C2C Internet auction market. The results also show that potential buyers are more sensitive to negative feedback when they are considering buying inherently risky products such as used or refurbished products.     

Groups Formation and Operations in the Web 2.0 Environment and Social Networks

The Internet and the Web are evolving to a platform for collaboration, sharing, innovation and user-created content—the so-called Web 2.0 environment. This environment includes social and business networks, and it is influencing what people do on the Web and intranets, individually and in groups. This paper describes the Web 2.0 environment, its tools, applications, characteristics. It also describes various types of online groups, especially social networks, and how they operate in the Web 2.0 environment. Of special interest is the way organization members communicate and collaborate mainly via wikis and blogs. In addition, the paper includes a proposed triad relational model (Technology–People–Community) of social/work life on the Internet. Particularly, social/work groups are becoming sustainable because of the incentives for participants to connect and network with other users. A discussion of group dynamics that is based on the human needs for trust, support, and sharing, regardless if the setting is a physical or virtual one, follows. Finally, future research directions are outlined.     

The effects of interface design and age on children's information processing of Web sites

Children increasingly utilize the Internet as a primary medium, a source of consumer information, and an important source of entertainment. This article investigates the influence of Web site design on children's information processing performance. A model is advanced that integrates theories from a variety of disciplines, including developmental psychology, human computer interaction (HCI), and consumer behavior. This study found that age moderates the relationship between Web site design and spatial (search) and learning (recall) performance. Younger children, between the ages of 7 and 9, recalled more content when using a map (as compared to a content list) and when learning cues were employed. Older children, between the ages of 10 and 12, performed equally as well with either a map or a content list, and with or without learning cues. Implications for business, education, and public policy are discussed and guidelines are provided for designing more child‐friendly Web sites. © 2008 Wiley Periodicals, Inc.     

Impact of auditory sense on trust and brand affect through auditory social interaction and control

Voice assistants—or voice-enabled artificial intelligence—have changed the way people interact with their surroundings dramatically. Utilizing an enactive view of social cognition theory, this study demonstrates how voice assistants can act as [semi] autonomous agents to hold instantaneous social interactions with consumers. This research employed two experimental studies. Study 1 used two voice assistant mobile applications, Microsoft Cortana and Google Assistant, and Study 2 used Amazon Alexa and Microsoft Cortana. The contributions this paper makes are two-fold. First, the results illustrate how perceived auditory sense drives perceived auditory control through auditory social interactions with a voice assistant that lead to brand affect and consumers’ trust in the voice assistant. Second, results shed light on the role of surprise as a repelling drive that attenuates the effect of perceived auditory control on brand affect.     

Trust,authentic pride,and moral reasoning: a unified framework of relational governance and emotional self‐regulation

This conceptual article introduces behavioral perspectives into the governance arena and undertakes a psychological assessment of managerial decision making in organizations by elaborating on the treatment of trust and (authentic and hubristic) pride in the extant literature. While trust is conceived by governance scholars as a device for monitoring relationships with others, we argue that authentic pride, contrary to hubris, could operate as an attribute of emotional self‐regulation allowing corporate leaders to govern the social behavior of their own self. Contrasting the features of trust and authentic pride, we advance several propositions to capture their relevance and simultaneous importance as viable governance mechanisms in light of a manager's level of cognitive moral reasoning. Our study builds a unified theoretical framework of governance which integrates human agency, psychological states, and moral judgment to foster a deeper understanding of complex self‐regulatory processes that are activated by decision makers in the execution of their roles.     

Does Social Software Support Service Innovation?

Recent Internet technologies and web‐based applications, such as social software, are being increasingly applied in firms. Social software can be employed for knowledge management and for external communication enabling access to internal and external knowledge. Knowledge, in turn, constitutes one of the main inputs to service innovation. Hence, social software has the potential to support service innovation. Using data from German IT and knowledge‐intensive service firms, this is the first paper that empirically analyses whether the use of social software applications triggers innovation. It refers to a knowledge production function in which social software use constitutes the knowledge sourcing activity. The results reveal a positive relationship between social software and service innovation. Since this result is robust when controlling for former innovative activities and the previous propensity to adopt new technologies and to change processes, the analysis suggests that the causality runs from social software to innovation.     

How Institutions Influence SME Innovation and Networking Practices: The Case of Vietnamese Agribusiness

This paper addresses impacts of the institutional framework on small and medium‐sized enterprise (SME) innovation and networking practices. Through an explorative study of a domestic SME‐dominated sector in Vietnam, we find that the institutional framework limits incentives for long‐term investments, resulting in exploitative cost‐control strategies rather than product‐oriented innovation. Due to dominating social norms, SMEs form trust‐based friendship networks, potentially limiting knowledge acquisition and weakening business rationality. Institutional pressures reinforce negative influences on SMEs' incentives to develop innovation ambidexterity. The findings suggest that new institutional economic sociology provides a promising foundation for understanding how institutional frameworks influence SMEs' innovation practices in emerging economies.     

Social cynicism,greenwashing, and trust in green clothing brands

This research develops a theoretical model of the effect of social cynicism as a personality trait on trust in green clothing brands. We conducted an online survey of a representative Australian sample to test the hypothesized relationships. Our findings confirmed that social cynicism affected green brand trust negatively and that this effect can be explained by an increase in perceived greenwashing. Conspicuous consumption moderates this indirect influence. This mediated influence decreased when conspicuous consumption was more salient. Findings provide important practical insights for brand managers intending to avoid a decrease in brand trust regarding garments marketed with sustainability claims.     

共享服务系统体验价值共创行为的影响因素

由于共享经济的发展和信息技术的进步,共享服务系统中的共创行为变得越来越容易实现,消费者与企业协作共创价值成为新的发展趋势。在消费者需求和共享行为都不断变化的情况下,如果共享服务供应商不清楚何种因素能够加速消费者价值共创行为的生成,则会影响共创价值实现。基于服务主导逻辑的理论,构建共享服务系统体验价值共创行为及其影响因素的理论模型。依据收集的450份有效问卷,对数据进行分析后发现,共享服务系统中感知利益、感知信任和社会可持续性通过互动协作(价值共创过程)对顾客体验价值产生影响,顾客体验价值对顾客的价值共创行为意向产生影响。研究结果表明,顾客参与共创动机中的效益动机和信任动机显著正向影响互动协作,互动协作显著正向影响体验价值和共创行为意向,而体验价值在互动协作和共创行为意向之间起到显著部分中介作用。共享服务提供方和产品制造方应多从顾客视角考虑其效益需求和信任需求,定位顾客需求和偏好,提供更有吸引力和说服力的商品与服务,使顾客感知到更多的收益,并形成较高信任度;提升与顾客的互动水平,建立顾客对服务方的好感,激发顾客更多的主动交互行为、参与行为和个人创新行为;重视资源的整合、分配和调动,实行以顾客驱动为核心的开放创新模式;招募优质用户,通过倾听和观察了解其价值主张,促进价值共创行为的生成,改善共享服务系统的整体服务质量。     

Avatars as salespeople: Communication style, trust, and intentions

Interactions with retail salespersons in stores contribute to building trust and profits. Within the largely impersonal Internet, an interactive animated character or avatar, playing the social role of an online sales assistant, should provide a potent source of social presence and so have the potential to replace some of these interactions. This investigation tests whether avatars with social- or task-oriented communication styles contribute to user trust and patronage intentions. Further tests explore the moderating effects of product/service type. The study includes an online experiment and survey, involving 636 participants, mainly from North America, Oceania and Europe, allocated randomly to different treatments.Task-oriented communications contribute to trust, which in turn contributes to patronage intentions, especially for search goods/services. Social-oriented communications also contribute directly to trust and to patronage intentions, most strongly for credence goods/services. The authors recommend a three-fold approach to avatar implementation, involving requirements captured to define appropriate appearance, role, interaction style and content for the task. Conclusions include further suggestions for development and research.     

Using Country Sustainability Risk to Inform Sustainable Supply Chain Management: A Design Science Study

The sustainability of our global supply chains is an essential concern in strategic supply chain management research. Modern information and communication technologies enable stakeholders to punish buying firms for any sustainability‐related grievances at their suppliers, even in remote locations. This study investigates how the notion of country sustainability risk can inform sustainable supply chain management, in particular with respect to sustainability risk assessment at the individual supplier level. Drawing on institutional theory, we provide insights surrounding the emergence of environmental, social, and governance‐related country‐level sustainability risks and show their implications for and application in sustainable supply chain management. The study employs a design science methodology, based on cooperation with a multidivisional German technology firm, to develop a supply chain sustainability risk (SCSR) map as technological solution design. This article contributes to the study of SCSR by reconciling the scholarly SCSR discourse with the buying firms’ pursuit of efficiency. Moreover, it elucidates the augmentation of a research agenda through a design science approach. In practical terms, the technological solution design can directly inform managers about SCSR at the country level and serves as a decision basis for the management of individual suppliers.     

TRUST AND VIRTUAL DISTRICTS: EVIDENCE FROM THE MILAN INTERNET EXCHANGE

Peering decisions between Internet Service Providers (ISPs) contain substantial non‐measurable aspects requiring trust and informal cooperation among peering partners. We study whether virtual districts are observed between Internet peers. Our empirical analysis of the bilateral peering decisions at the Milan Internet Exchange confirms that these decisions are significantly influenced by: travel time either between ISPs' headquarters or towards the exchange—a proxy for distance, bandwidth—a proxy for size, and European connectivity. Proximity still plays a role in reducing the transaction costs of monitoring and punishing deviant behavior within an industry where trust is essential for Internet universal connectivity.     

A comparison of alternative theoretical explanations of consumer food safety assessments

The technical approach assumes that risk assessments made by technical experts are relatively objective and value‐free evaluations of the probability of negative consequences arising from use of a technology. Risk communication strategies associated with the technical approach focus upon educating an uninformed public about ‘actual’ risk. When consumer perceptions do not agree with technical assessments, consumers are deemed to be uniformed, irrational and sometimes dangerous to public health programmes. The social process approach assumes that technical assessments and applications of technology are influenced by political, social and economic interests. Consumer perceptions arise from social interaction with family and friends and depend strongly upon trust in societal institutions. Risk communication strategy emphasizes the importance of two‐way communication that encourages well reasoned public discourse and trust in societal institutions. Findings from examining the cognitive, emotional, and social determinants of perceptions of food irradiation for 164 adults residing in the Mid‐western USA indicate that the technical and social process approaches are complementary, but most of the variance in acceptance and perceived risk was explained by variables associated with the social process approach.     

Multi-dimensional role of trust in Internet banking adoption

Trust has been identified as the key to e-commerce because it is crucial wherever uncertainty and interdependence exist. The strong association between a high level of trust and the banking sector has not yet been fully translated in the electronic world. The aim of this article is to develop and validate a multi-dimensional model of trust for Internet banking. The data are collected through 441 Internet banking users of Halifax Bank of Scotland. Findings suggest that trust and perceived risk are direct antecedents of intention, and trust is a multi-dimensional construct with three antecedents: perceived trustworthiness, perceived security, and perceived privacy.     

Nicknames as identity badges: How self-reflective nicknames can facilitate users’ online social interactions

An Internet nickname is essential in facilitating online interpersonal interactions. It is a pivotal element of interaction that provides other users with an initial impression and affects the decisions and behaviors of users during their online interactions. Although the existing literature has found that nicknames are relevant to users’ psychology and behavior, direct research on the motivation for and the effect of choosing a particular Internet nickname has been very limited. Borrowing from relevant theories on avatars, this paper summarizes the motivations behind Internet nickname choices in terms of three aspects: virtual exploration, social navigation and contextual adaptation. Moreover, from the perspective of collective self-esteem (CSE) and group identification, this research explores the influence mechanism between the motivations underlying Internet nickname choices and users’ online social interactions. A total of 394 samples were obtained from online communities in China to test our research model. We found that virtual exploration, social navigation and contextual adaptation are three motivations for creating Internet nicknames, and they have direct effects on the online social interactions of users. CSE has a full mediating effect between virtual exploration and online social interaction and acts as a mediated variable between social navigation and online social interaction. Group identification fully mediates the relationship between social navigation and online social interaction as well as that between contextual adaptation and online social interaction. The conclusion of this paper provides not only a new perspective for the study of Internet nicknames but also a potentially feasible way to stimulate users’ online social interactions.     

Revisiting the Honorable Merchant: The Reshaped Role of Trust in Open Innovation

We examine trust mechanisms in innovation within a number of inter‐ and intraorganizational contexts and outline the challenges posed by open innovation to those mechanisms. The organizational contexts that we have chosen for examination are supply chain development, clusters, and employee involvement. We argue, through an in‐depth literature review that is supported by examples, that trust is being highly reshaped to better suit the growingly open innovation environment, which in many ways resonates with the historical concept of the honorable merchant. Our findings provide a better understanding of how trust facilitates the flow of information in open innovation and show how trust is becoming increasingly intermediated. Our systematic overview provides a rich context for further empirical research and innovation management practice. © 2015 Wiley Periodicals, Inc.     

Antecedents of Perceived Quality in the Context of Internet Retail Stores

This study investigates specific antecedents of perceived service quality in the Internet environment for trust to a retail store, experience with e-commerce, Internet familiarity, excitement with e-commerce, extent of using e-commerce, frequency of purchases from a company, in addition to exploring the reasons for shopping on line: such as price discounts, convenience, product availability, and purchase conditions. The results indicate that perceived e-service quality is comprised of four key dimensions: information, user friendliness, interaction / adaptation and aesthetics. Moreover, the study reveals that different dimensions of perceived e-service quality are influenced by diverse antecedents. For instance, whilst customer trust to a company influences all four dimensions, Internet familiarity has an impact solely on user friendliness. This picture remained when the type of store, either pure dot. com versus hybrid retailer, was tested as a moderator variable. Implications for practice, the limitations of the study, and directions for future research are discussed.
