How socially derived characteristics of technology shape the adoption of corporate Web 2.0 tools for collaboration

Socially derived characteristics (perceptions of individuals about technology-related characteristics) of Web 2.0 tools are not generally taken into account when decisions are made about which systems to use for collaboration in corporate settings. This exploratory research studies the influence of these characteristics—perceived compatibility, social presence, and group supportability—in the adoption of corporate blogs and validates a theory-grounded model with data from 73 employees. The results show that social presence and users’ values influence perceived usefulness of corporate blogs and play an important role in their adoption, while existing work practices, prior experience and group supportability do not.     

The Role of Marketing in Digital Business Platforms

Digital business platforms (DBPs) such as eBay, Google, and Uber Technologies have seen enormous growth; this paper explores their salient characteristics, the role of marketing in helping DBPs succeed, and important research topics for theory and practice. A new conceptual framework based on insights from transaction cost analysis outlines the role and impact of marketing in DBPs. A key role for marketing is to increase the number and quality of interactions on a DBP while reducing transaction costs for users and production costs for the DPB. The DBPs' interactions and the data thus generated are key enablers of value creation and value appropriation on these platforms. However, there are several challenges to resolve in value creation and value appropriation because DBPs cater to the needs of many different types of users. Therefore, DBPs should carefully coordinate and manage interactions among users on different sides of a platform. For researchers, there are many opportunities to reconceptualize some of the traditional roles of marketing in the context of DBPs.     

A Public Sector Marketing Model to Measure the Social and Environmental Values of Public Strategies: An Empirical Study on a Green Public Service

This article develops a public sector marketing model to measure the social and environmental values of public strategies. Applying partial least squares path modeling, the authors empirically test the model by conducting a quantitative survey (N = 603) among users of a green public service in the form of a public bike-sharing system. The findings reveal that users simultaneously perceive public outcomes on the social value and environmental value dimensions. The effect estimated on the perceived social value dimension of the green public service was slightly stronger than the effect on the environmental value dimension. Thus, users primarily perceive self-centered values, before considering values generated for the environment. The findings also show that engaging citizens now in the actual usage of green public services can foster green consumption intentions in the future.     

Internet consumer value of university students: E-mail-vs.-Web users

What values are underlying the use of Internet? An empirical study (N=358) shows five value factors: social, utilitarian, hedonic, learning and purchasing on the Internet. World Wide Web users score significantly higher on social and learning value, while E-mail users tend to value more a communication experience rather than a learning experience. Theoretical and practical implications are proposed.     

Antecedents of mobile payment loyalty: An extended perspective of perceived value and information system success model

Drawing on the information system success model and perceived value theory, we develop a research model to examine factors that may affect user satisfaction and loyalty of mobile payment platforms. Empirical data was collected from users using Alipay and WeChat Pay in China, and a total of 410 valid responses were gathered for data analysis. The results show that the multi-dimensional formative perceived value including benefits and sacrifice is important determinant of mobile payment user satisfaction and loyalty. The three benefit dimensions of functional value, experiential value and social value are more important value components than the two sacrifice dimensions of risk and cost, and experiential value is the dominant component of mobile payment users' value perception. As for the antecedents of perceived value, system quality and service quality mainly affect perceived benefits, while information quality has a greater impact on risk. The research results provide the contribution of specific value dimensions to users' perceived value and the impact of quality characteristics on specific perceived value for mobile payment platform providers, thus helping them to adopt effective strategies to strengthen market competitiveness and retain existing users.     

More gain,more give? The impact of brand community value on users’ value co-creation

Users' value co-creation behaviors contribute to the prosperity of brand communities as well as brand performance. This article aims to answer a basic question: are brand community users who obtain more value from the brand community more willing to co-create value? If so, why and under what conditions? Drawing from reciprocity theory, this study proposes that information value and social value lead to value co-creation by evoking users' reciprocity norm, and this effect depends on their self-presentation in the community. Results based on structural equation modeling combining survey data and archival data largely validate this framework, revealing that the reciprocity norm mediates the influence of brand community value on value co-creation. Additionally, information value increases value co-creation only when the level of self-presentation is high, and the positive effect of social value is not altered by self-presentation. By uncovering the mechanism and boundary conditions of how brand community value affects users’ value co-creation behaviors, this study extends the current literature on value co-creation and provides important practical implications.

对于分布式的认知无线网络,由于不存在融合中心节点,次级用户节点之间的合作感知往往 采用信息交互的渠道进行,其中一种基于共识合作的感知机制受到广泛的研究,但这种机制 在鲁棒性方面存在一定的缺陷,当恶意节点存在时,其错误信息将影响局部的感知判决结果 ,为此,提出一种基于感知节点可信度的共识合作感知机制。在该机制中,各节点对邻居节 点的可信度进行计算,并把计算出的可信度值发送给其他节点,通过对各节点可信度的累加 计算,最终计算出各节点的可信度,各节点以此决定是否与其邻居节点合作以及如何合作。 仿真结果证明,在恶意节点存在的情况下,该算法在感知性能和收敛速度上都较未改进算法 有不同程度的提升,减轻了不可靠节点对合作感知结果的影响。     

Untangling the relationships between consumer characteristics,shopping values,and behavioral intention in online group buying

This study examines the link among consumer characteristics (price-sensitive behavior, variety-seeking behavior, and compulsive buying behavior), shopping values (utilitarian and hedonic shopping values), and behavioral intention in online group buying (OGB). This study tests usable responses collected by means of mall-intercept systematic sampling from consumers who previously participated in OGB. Structural equation modeling was used to analyze data and test the hypothesized relationships. Findings suggest that price-sensitive and variety-seeking behaviors are significantly related to utilitarian shopping value, whereas price-sensitive, variety-seeking, and compulsive buying behaviors are significantly related to hedonic shopping value. Both utilitarian and hedonic shopping values significantly influence consumers’ OGB intentions. For a successful OGB strategy, Internet marketers and site operators should emphasize the utilitarian shopping value of price saving and selection and introduce the hedonic shopping values of promotions and sensory experiences. This study provides a link between two streams of prior research – that is, consumer characteristics and shopping values. Furthermore, it validates an empirical model whose results can help business practitioners make better-informed marketing management decisions for OGB and help academics and consumers better understand OGB behavior.     

Effect of price increases on future intentions of sport consumers

This work analyzes the relationships between perceived value, satisfaction and future intentions among users of a public sport service who experience a price increase in the service they receive. A self-administered survey provides data from two samples (before and after the service price increase). After confirming the reliability and validity of the measures, hierarchical multiple regression provides the means for analyzing the data. The results show that the increase in the service price worsens the perception of service performance. As expected, satisfaction, perceived value and future intentions decrease following an increase in the service price. Perceived value also serves as a more effective predictor of future intentions than satisfaction. Finally, price increase has a low direct effect on predicting future intentions of sport users.     

The use of foreign currency derivatives,corporate governance,and firm value around the world

This paper examines the impact of currency derivatives on firm value using a broad sample of firms from thirty-nine countries with significant exchange-rate exposure. Derivatives can be used for managers' self-interest, for hedging or for speculative purposes. We hypothesize that investors can appeal to a firm's internal (firm-level) and external (country-level) corporate governance to draw inferences on a firm's motive behind the use of derivatives, since well-governed firms are more likely to use derivatives to hedge rather than to speculate or pursue managers' self-interest. Consistent with this explanation, we find strong evidence that the use of currency derivatives for firms that have strong internal firm-level or external country-level governance is associated with a significant value premium.     

Influencing factors of customer loyalty in mobile payment: A consumption value perspective and the role of alternative attractiveness

The rapid development of mobile payment has attracted many competitors and made customer retention a crucial issue for mobile payment service providers. This study examines the influencing factors of mobile payment loyalty from a multi-dimensional value perspective by extending and integrating the Cognitive-Affective-Behaviour (C-A-B) model and the Theory of Consumption Values (TCV). We also incorporate alternative attractiveness as a moderating variable to reveal the potential influence of the competitive market environment. This study collected 427 questionnaires from mobile payment users in China. The empirical study results show that customers’ loyalty is determined by satisfaction, and satisfaction is influenced by functional, emotional, epistemic, and monetary value. The findings also demonstrate that satisfaction has mediated the consumption values and loyalty relationship, and alternative attractiveness has weakened the influence of satisfaction on loyalty. This study shifts the focus in mobile payment research from adoption to the post-adoption stage and establishes a new research model by integrating two fundamental theories in explaining customer behaviour. Our study could guide mobile payment providers to cultivate customer satisfaction and loyalty by determining the values that are worth investing in their marketing strategies and help them notice and neutralise the weakening effect of competitor attractiveness.     

Impact of service personal values on service value and customer loyalty: a cross-service industry study

This study investigates the customer’s perception of service value based on theory of personal values. A formative structural model is developed and tested using the data surveyed from three service industries in Vietnam. Results show a positive impact of service personal values on service value. Then, service value and satisfaction are proved as two mediating constructs in the impact of service personal values on customer loyalty. Satisfaction and loyalty are, thus, not only determined by the supplier’s service itself, but also the customer’s personal values. This consolidates the value co-creation perspective rather than the traditional value exchange in service research.     

A consumer value analysis of mobile internet protocol television based on a means-end chain theory

With the rise of the 4G technology, TV or video services based on mobile devices have received increasing attention from consumers. Using means-end chain theory, this study examines the cognitive structure of mobile internet protocol television (IPTV) users. Here, the cognitive structure refers to the attribute–consequence–value linkage that consumers consider as important in mobile IPTV services. The study classifies consumers based on two dimensions (their gender and occupation) and presents hierarchical value maps of mobile IPTV services. For this, the study collects data on 112 potential users of mobile IPTV services by using the association pattern technique. The results indicate as the representative cognitive structure of men and students; as that of women; and as that of office workers.     

Factors affecting users’ continuance intention of mobile social network service

This study investigates the factors that influence users’ intention to continue using social network service applications (apps) on mobile devices. We drew on the uses and gratifications (U&G) paradigm and innovation diffusion theory; these were augmented with the factors that characterize mobile social network service (MSNS) usage. The proposed framework explained the relationships between these factors and the intention to continue using MSNS apps. A web-based survey was used to collect data for analysis. The results indicated that critical mass, mobility, compatibility, purposive value, and entertainment value were important drivers of users’ intention to continue using MSNS apps. The findings contribute to existing U&G paradigm, innovation diffusion theory, and MSNS usage literature. The paper closes with a discussion of useful insights relevant to researchers and practitioners in terms of developing and implementing MSNS apps that have high retention rates.     

Opportunities and Challenges Facing the Bureau of Labor Statistics

The Bureau of Labor Statistics (BLS) is one of the most important sources of data for business economists. This paper describes recent and planned new products, improvements to existing products, and improvements in users’ ability to access data. It also describes initiatives within the BLS to make it even more efficient and responsive than it is at present, including means of providing feedback from users. The paper also emphasizes the importance of users in responding to requests for survey information and support of BLS programs.     

Modeling discontinuous periodic conditional volatility: Evidence from the commodity futures market

This paper examines a wide variety of models that allow for complex and discontinuous periodic variation in conditional volatility. The value of these models (including augmented versions of existing models) is demonstrated with an application to high frequency commodity futures return data. Their use is necessary, in this context, because commodity futures returns exhibit discontinuous intraday and interday periodicities in conditional volatility. The former of these effects is well documented for various asset returns; however, the latter is unique amongst commodity futures returns, where contract delivery and climate are driving forces. Using six years of high‐frequency cocoa futures data, the results show that these characteristics of conditional return volatility are most adequately captured by a spline‐version of the periodic generalized autoregressive conditional heteroscedastic (PGARCH) model. This model also provides superior forecasts of future return volatility that are robust to variation in the loss function assumed by the user, and are shown to be beneficial to users of Value‐at‐Risk (VaR) models. © 2004 Wiley Periodicals, Inc.

Advertising and Cultural Values: Reflections in the Distorted Mirror

This paper reviews the regrets and fears expressed by North American scholars about the commercialization of culture and presents a method for measuring the cultural character of advertising. This content analysis of manifest values yields a value profile of advertising and shows high consistency over time and across media. There is, however, a low correlation between this value profile and that of either the population at large or of heavy media users. This seriously challenges the conventional notion that advertising merely mirrors social values.     

Switching asymmetric GARCH and options on a volatility index

Few proposed types of derivative securities have attracted as much attention and interest as option contracts on volatility. Grunbichler and Longstaff (1996) is the only study that proposes a model to value options written on a volatility index. Their model, which is based on modeling volatility as a GARCH process, does not take into account the switching regime and asymmetry properties of volatility. We show that the Grunbichler and Longstaff (1996) model underprices a three‐month option by about 10%. A Switching Regime Asymmetric GARCH is used to model the generating process of security returns. The comparison between the switching regime model and the traditional uni‐regime model among GARCH, EGARCH, and GJR‐GARCH demonstrates that a switching regime EGARCH model fits the data best. Next, the values of European call options written on a volatility index are computed using Monte Carlo integration. When comparing the values of the option based on the Switching Regime Asymmetric GARCH model and the traditional GARCH specification, it is found that the option values obtained from the different processes are very different. This clearly shows that the Grunbichler‐Longstaff model is too stylized to be used in pricing derivatives on a volatility index. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:251–282, 2004     

Consumer acceptance of fatty spreads

The effect of consumer trends on the purchase of reduced fat products in general and fatty spreads in particular are discussed. A variety of fatty spreads with fat levels ranging from 20 to 80% were assessed by cone penetration measurements and sensory assessments. The results indicated that butter had poor spreadability characteristics at 5° and 10°, while mechanically worked butter (spreadeasy butter) gave a significantly different texture profile, as measured by the Instron Model 1000. This butter type was assessed as being spreadable at 10° by the sensory panelists and by cone penetrometry. Comparable values of hardness were obtained using data obtained by cone penetrometry and texture profile analysis from the Instron. Low fat spreads (fat levels 25–39%) produced desirable spreadability characteristics using both objective and subjective methods of assessment. Sunflower oil-based spreads and very low fat spreads, i.e. ≦ 25% fat, were assessed as being soft and oily. The results overall indicated that the use of a cone penetrometer and the subsequent calculation of a yield value gave, using Haighton's seven-point scale, a good indication of spreadability characteristics.
