Web retailing adoption: exploring the nature of internet users Web retailing behaviour

The interaction of consumers and marketers within the Web environment, particularly for retailing/purchasing is a growing area of importance. This paper focuses on examining Internet users adoption of the Web for retail usage. It uses the Technology Acceptance Model Davis (Int. J. Man-Mach. Studies 38 (1993) 475) as a theoretical foundation to explore adoption of this technology for retail usage. The study also adds what are argued to be key consumer characteristics such as Opinion Leadership, Impulsiveness, Web Shopping Compatibility, Internet Self-Efficacy, Perceived Web Security, Satisfaction with web sites, and Shopping Orientation to understand the adoption of Web retailing by Internet users’. A Web based survey was developed and administered, yielding 392 responses. The findings indicate that TAM is a valid theoretical framework to understand users adoption of the Web for retail purposes. Also Internet users’ perceived usefulness and perceived ease of use were effected differentially by Opinion Leadership, Web Shopping Compatibility, Internet Self-Efficacy, Perceived Web Security, Impulsiveness, Satisfaction with web sites, and Shopping Orientation.

Pricing and Cost Recovery for Internet Services: Practical Review,Classification, and Application of Relevant Models

Suitable pricing models for Internet services represent one of the main prerequisites for a successfully running implementation of a charging and accounting system. This paper introduces general aspects influencing the choice of a pricing model in practical situations and presents a survey as well as a classification of relevant and advanced approaches to be found in the scientific literature. First performance results on charging extensions within the Internet are presented, which are completed by a set of market price simulations for dynamic pricing models within the same implementation environment. Based on cost model investigations some detailed insights into price and cost issues from an Internet Service Provider's (ISP) point of view are given. Moreover, current challenges as well as problems are discussed in a practical context as investigated in the Swiss National Science Foundation project Charging and Accounting Technology for the Internet (CATI).     

Commitment,Trust, and Social Involvement: An Exploratory Study of Antecedents to Web Shopper Loyalty

Winning customer loyalty is viewed as a priority by many electronic (e) businesses. Grounded in the theory of reasoned action, our proposed model suggests that commitment is a key attitudinal antecedent to Web shopper loyalty. In the model, we introduce trust in the Internet and social involvement in a Web consumption community as moderators of the commitment-loyalty relation. The model was tested using data from a survey of Web users. Preliminary results provide general support for commitment as a determinant of loyalty and social involvement magnifying the strength of that relation. Trust in the Internet did not attenuate the commitment-loyalty relation. We offer implications and directions for future research.     

Promotional strategies on the World Wide Web

Business managers that use the Internet as a major component of their marketing communications strategy face great challenges. The popularity of the Internet with consumers and businesses drives thousands of firms to promote their products and services using World Wide Web (known hereinafter as the Web) sites. Technology has created a competitive arena that enables exposure to consumers worldwide, who can now easily communicate with each other. This potential for exposure has dramatic implications for any business considering the Internet as a promotional vehicle. The growing popularity of Internet sites, where users may discuss their feelings about companies and products, allows an increased scrutiny of all aspects of business. If companies do not deal effectively with this scrutiny, brand equity is vulnerable to erosion. Therefore, all contingencies inherent in promotional efforts on the Internet must be weighed carefully. Businesses which examine the ramifications of on-line exposure are better able to create and maintain a positive Internet presence which facilitates effective Web site promotion. Planning, implementation and control must be integrated into the on-line marketing communications of businesses, regardless of business size.     

Click Here for Internet Insight: Advances in Clickstream Data Analysis in Marketing

Clickstream data are defined as the electronic record of Internet usage collected by Web servers or third-party services. The authors discuss the nature of clickstream data, noting key strengths and limitations of these data for research in marketing. The paper reviews major developments from the analysis of these data, covering advances in understanding (1) browsing and site usage behavior on the Internet, (2) the Internet's role and efficacy as a new medium for advertising and persuasion, and (3) shopping behavior on the Internet (i.e., electronic commerce). The authors outline opportunities for new research and highlight several emerging areas likely to grow in future importance. Inherent limitations of clickstream data for understanding and predicting the behavior of Internet users or researching marketing phenomena are also discussed.     

Effects of pricing on Internet user behavior

The INternet Demand EXperiment (INDEX) conducts experiments to measure demand for quality-differentiated Internet access as a function of bandwidth, traffic volume, applications, and pricing structure. This paper presents an overview of results based on aggregated data from five pricing experiments. In these experiments, pricing is based either on time, volume, a combination of both, or a flat-rate buy out option. Quality of Service (QoS) is differentiated by varying bandwidth for incoming and outgoing traffic. After describing the experimental design and characterizing our subject pool using demographic data, we examine the change in service usage by comparing the five experiments in terms of traffic generation, QoS selection, and expenditure.     

Consumer benefit versus price elasticity of demand: a nonlinear complex system model of pricing internet services on QoS-centric architecture

Based on complex system considerations, a technoeconomic model to depict the extent of consumer reaction (in terms of consumer surplus, V) to changes in Internet pricing is developed. Relevant research pursuit tracks analytically, the nonlinear evolution of the functional relation in question with various stochastic (and/or deterministic) technoeconomic parameters that interactively decide the underlying complexity. Hence, an explicit function is derived to relate the fractional change in V and the price elasticity of demand (E) specific to differentially classifiable services on Quality of Service (QoS) (DiffServ)-centric Internet architecture. The model is applied to dynamic-, smart- and static-market pricing schemes. Results are discussed with respect to some model simulations.     

Web site customer orientations, Web site quality, and purchase intentions: The role of Web site personality

This research extends the concept of salesperson customer orientation to Internet marketing by conceptualizing and studying the effects of Web site customer orientation on perceived Web site quality and consumer behavior. This research also adapts the concept of brand/store personality to Internet marketing by investigating the effects of Web site personality on perceived Web site quality and consumer purchase intention. The model is tested on apparel Web sites using data from multiple sources. Implications of managing Web site personality and Web site customer orientation are discussed.     

Preventing competition using side payments: when non-neutrality creates barriers to entry

Network neutrality is often advocated by content providers, stressing that side payments to Internet Service Providers would hinder innovation. However, we also observe some content providers actually paying those fees. This paper intends to explain such behaviors through economic modeling, illustrating how side payments can be a way for an incumbent content provider to prevent new competitors from entering the market. We investigate the conditions under which the incumbent can benefit from such a barrier-to-entry, and the consequences of that strategic behavior on the other actors: content providers, users, and the Internet Service Provider. We also describe how the Nash bargaining solution concept can be used to determine the side payment.     

Pricing Internet access in the presence of user loyalty

Socio-economic aspects of future communication networks such as pricing models for network providers, network neutrality, and Quality of Experience (QoE) are becoming more and more important as the convergence of networks is in progress. All the above areas share a common interest: the deeper understanding of user behavior. In this paper, as a first step towards a more realistic user model, we investigate customer loyalty and its impact on the pricing competition of Internet Service Providers (ISPs) who sell Internet access to end-users. The main contribution of this paper is twofold. First, we analyze the impact of user loyalty with game-theoretical means motivated by the Bertrand game. We show how loyalty introduces a new equilibrium in a repeated game setting resulting in the cooperation of ISPs. Furthermore, we investigate the case of a differentiated customer population by introducing dual reservation values, and show how it leads to new, pure strategy Nash equilibria indicating that ISPs should make the most out of their respective loyal user base. Second, we construct two novel models for customer loyalty incorporating two important aspects of the users’ purchasing decisions: price sensitivity and inherent uncertainty. We evaluate the impact of user loyalty through these models by extensive simulations in a number of relevant scenarios. In particular, we show how the higher level of loyalty in the user population leads to larger profits for ISPs. We argue that our findings can motivate network researchers to incorporate a finer-grained user behavior model in their investigations on pricing models of network services and other socio-economic issues.     

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.     

Arrow: A flexible architecture for an accounting and charging infrastructure in the Next Generation Internet

Current pricing and charging methods for the Internet are not based on actual usage of this service, which leads to unfairness and more important, it does not deliver the right signals through financial incentives to network providers to upgrade critical links of their networks. The development of new multimedia applications and the convergence to an integrated services network will foster the tremendous growth of the Internet even more. With the Next Generation Internet not only technical services like bandwidth reservation will be introduced, but also new applications will emerge within the Internet. Charging the Internet in a fashion that provides feedback to users and providers has been proposed since the early '90s, however, only a few implementations and real-world examples are known today. This is due to subsidizing the Internet in its early stages and due to a technical development that did not care much about charging. With the recent redesign of the Internet protocol suite and discussions on multiple service classes in the Internet, architectures for charging and accounting have to be revisited, too. Economic models for the Internet cannot be tested fully and validated in non-real-world environments, because of the unknown user behavior. With this uncertainty over what models and pricing schemes to choose, it is evident that a specific charging and accounting platform will never be accepted by the community. In this paper a novel and flexible architecture for charging and accounting is proposed that provides a wide range of mechanisms and lets researchers experiment in an environment as close as possible to the targeted system. As a first step, four different pricing schemes are described, qualitatively assessed on the proposed platform, and a prototypical implementation performed. One of the economic models that have been implemented on Arrow is based on different service classes including reservation and recalculates prices dynamically depending on the traffic situation.

How User‐Created‐Content (UCC) Service Quality Influences User Satisfaction and Behaviour

The Internet is undergoing a gradual shift from Web 1.0‐based user interaction to Web 2.0, which has a greater emphasis on user‐created content (UCC) and user collaboration (Hsu & Hsu, 2008). Since existing models of e‐service quality are likely deficient under Web 2.0, we build on them and test a new framework using 319 users who frequented UCC websites. Among other findings, three service elements together explained 44% of the variance in user satisfaction and 33% of the variance in website usage. These elements were: the provider‐user relationship (customization and participation), the relationship among users (e.g., user empowerment), and user compensation. Copyright © 2012 ASAC.

The role of perceived control and gender in consumer reactions to download delays

An empirical study finds that perceived control strongly mediates the effects of perceived speed of a Web site download on consumers' attitudes and intentions to use the Web site. Moreover, results show that men are more likely to react positively to the perceived speed of a Web site download, whereas women are more likely to base their reactions on perceptions of control in the context of download delays. In contrast to past online research, the gender differences are intrinsic in two ways—they are context independent, and they are not caused by length of Internet experience, extent of Internet usage, or type of Internet connections.     

Countering Service Information Challenges in the Internet of Services

Business Webs apply the idea of value networks to the WWW. The underlying delivery platform is commonly referred to as the Internet of Services and will certainly have to deal with a great variety and amount of information about services along several service information dimensions. As soon as brokerage, discovery, or community feedback parts are decentralized, there emerge a number of service information challenges (modeling the information in a holistic way, documentation, interlinkage, tool interoperability, distributed querying, inconsistent information, and cooperation of different stakeholders). In this paper, we propose to counter such service information challenges by two artifacts. First, we contribute a Service Ontology based on a sound and rigid foundational ontology. The Service Ontology provides a holistic and consistent way of capturing service information. We apply the recommendations of the W3C Semantic Web Activity whose recent standardization has already opened new possibilities for tool interoperability, interlinkage of information, and distributed querying on the web. However, building and prescribing an ontology in standardized languages is not enough to address all service information challenges. Therefore, as a second contribution, we provide a method around the ontology including a governance framework, guidelines for applying the W3C Semantic Web recommendations, a lifecycle-spanning tool chain, and different levels of applicability. We label our method Semantic Business Web approach, since we build on W3C Semantic Web standards, use and extend them in the Business Web setting. Both artifacts are constructed in an interdisciplinary way by experts participating in the German lighthouse project THESEUS/TEXO. The project’s scenario also serves as a proof of concept evaluation of the artifacts.     

The effect of host country Internet infrastructure on foreign expansion of Korean MNCs

This study examines the effect of host country Internet infrastructure on a multinational corporation (MNC) foreign expansion. Using Heckman’s selection model on a sample of 2589 subsidiaries of 487 Korean MNCs between 1990 and 2011, we find that host country Internet infrastructure is important in MNC expansion decisions. In addition, we find that a well-developed Internet infrastructure within a host country leads to more investments from MNCs producing consumer over industrial goods and is more attractive to domestic market followers than market leaders. We find that the host country’s Internet infrastructure is important for an MNC foreign expansion decision, suggesting that efficient communication within an MNC is critical in coordinating globalized MNC subsidiary operations.     

Big content providers weighing on non-neutrality?

There is a trend for big content providers such as Netflix and YouTube to give grades to Internet Service Providers (ISPs), to incentivize those ISPs to improve at least the quality offered to their service. We design in this paper a model analyzing ISPs’ optimal allocation strategies in a competitive context and in front of quality-sensitive users. We show that the optimal strategy is non-neutral, that is, it does not allocate bandwidth proportionally to the traffic share of content providers. On the other hand, we show that non-neutrality does not benefit ISPs but is surprisingly favorable to the perceived quality for users.

     

Factors affecting Internet shopping behaviour in Singapore: gender and educational issues

Despite the increasing number of online users and products that are being offered on the Web, there is relatively little work that specifically examines the role of gender and educational level on the attitudes of Internet users in the Singapore context. Our findings reveal that there is a general consensus amongst Singaporeans that the Internet is a convenient medium for information search or making purchases. The better‐educated respondents seem to be less concerned with security issues. They also perceive that Internet shopping provides better prices and more cost savings. Females indicate a strong dislike for not being able to savour a physically fulfilling shopping experience online.
