This study reexamines the value relevance of e-commerce announcements using an event study methodology. Event studies have become an increasingly popular technique for information systems research by giving researchers a tool to measure the notoriously elusive value of information technology. We find evidence that the traditional event study methodology may not provide an accurate measure of abnormal returns during periods of high market volatility, and propose an alternative methodology. The alternative methodology does not use an estimation period, and takes into account extreme or unusual market movements in the period in which the e-commerce announcement was made. Using the alternative methodology, we find evidence of positive abnormal returns for e-commerce announcements made in the fourth quarter of 1998, but no abnormal returns to e-commerce announcements made in the fourth quarter of 2000. We also find significant differences in value depending on the type of e-commerce initiative. In 2000, e-commerce initiatives with a digital product were valued significantly more than e-commerce initiatives with a tangible product, while in 1998 no such difference existed. In 1998, business-to-business e-commerce initiatives, e-commerce initiatives with a tangible product, and e-commerce initiatives by pure-play Internet firms were valued more than similar initiatives in 2000. The study makes a significant contribution for understanding the value of e-commerce initiatives in highly volatile markets and demonstrates how market values of e-commerce changed from 1998 to 2000. Furthermore, this study shows the importance of carefully considering both the time frame examined and the methodology used when assessing the value relevance of e-commerce initiatives as to avoid inflating the magnitude of any observed effects.

Sets forth a program of research for identifying the pertinent issues that are affecting the adoption and use of mobile electronic commerce applications and collaborative mobile technologies. The primary vehicle for understanding these issues is the observation and analysis of how different cultures utilize these emerging technologies. For example, why is short message service (SMS) messaging so popular in Europe but barely used in the USA? A review of the existing and near-future technologies is provided, along with the differences in national infrastructure as well as culture. The roles of cognitive fit and the technology acceptance model (TAM) in addressing these questions are reviewed, along with other relevant literature. Finally, a listing of research questions and a research plan for testing them is detailed.

Electronic commerce (EC) can be defined as an online exchange of value. This article presents an analysis of 172 published research articles and synthesizes their content by theoretical perspective (organizational, economic, and technical) and dominant research methods. We use this analysis to identify specific research themes within a framework that have the potential to become cumulative streams of research. One conclusion is that EC research to date has been widely scattered in a variety of journals and is often not self-referencing. This analysis provides a step toward remedying this problem by specifically synthesizing what is known to date from EC research and by proposing directions for future efforts. A second conclusion is that the field of information systems (IS) has a window of opportunity to become a primary producer and conveyer of EC research knowledge if cumulative streams of research can be nurtured and published in top-tier journals. The analysis presents a context for examining IS opportunity and the necessary antecedents.

Abstract.Today mobile network operators offer a wide variety of mobile Internet services to their customers including mobile email, banking, and news services. The acceptance of these services is heavily based on quality of service (QoS) experienced by the user. So far the discussion of QoS has been very network centric and the key to user satisfaction has been the network performance. In this paper we analyze the relationship between QoS perceived by the customer and network performance offered by the service provider. We conduct a lab experiment where network performance variables were controlled. Statistical analysis of the results indicates that there is no 1:1 correspondence or even truly linear relationship between network performance and perceived QoS as recommended by the International Telecommunications Union-Telecommunication (ITU-T). Instead the relationship varied from application to application. We examine several usability factors as potential reasons behind this phenomenon and make suggestions for future research.

The advantages arising from the emergence of electronic commerce (EC) are manifold. From automating inventory replenishment to replacing traditional sales channels with Web-based interfaces, the concept of electronic commerce presents a number of research challenges and opportunities. A key prerequisite for leveraging EC applications is a thorough understanding of how customers interact with these applications. A primary challenge for the successful design and implementation of these applications is managing not only the increasingly heterogeneous nature of the task performed in the context of EC, but the wide variety of interaction devices (e.g., wireless phones, PDAs, etc.) that customers use to execute these tasks. The significance and primary contribution of this research effort is to adapt and apply task-technology fit (TTF) theory to an EC domain. Using the techniques outlined by Goodhue (1995), TTF constructs for an EC task domain are derived by applying factors/principles from Web usability research. The TTF determinants of task, technology, and individual characteristics are modified to fit an EC domain. An electronic commerce TTF instrument is presented along with a research model for better understanding the relationships between independent and dependent variables. Finally, plans and implications for future research are discussed.

It has been proposed by many in our field that the discipline of Information Systems requires a shift in teaching and research. Historically, the field has been focused on the transformation of data into information and in this track, we take the view that this has, for the most part, already occurred. Further, there is new research being published about the transformation of information to knowledge and knowledge to wisdom. For this track, research proposals, education curricula, and papers that illustrate and/or demonstrate this shift, or even cases that argue against this stance were invited. The minitrack has attracted a focussed range of papers, from which that selected was on the basis of its value for researchers as a case study from a large organisation in which some of these issues were addressed. The field of Systems Science, as with most computing fields, is experiencing the effect of changing paradigms. In this time of big data, the minitrack chairs invited authors to consider how we can get big knowledge or big breakthroughs to resolve the problems our planet and societies face, now and in the future. Solutions to environmental, health, and energy problems require extensive knowledge bases that traditional MIS curricula and research appear to fail to address. At the track, we intend to stimulate dialogue amongst IS faculty and professionals to shift our discipline towards greater relevance. The issue of relevance has been discussed for many years, but now is the time to make pragmatic changes. 2014 47th Hawaii International Conference on System Science
