摘要：We present a model to investigate the competitive implications of electronic secondary markets that promote concurrent selling of new and used goods on a supply chain. In secondary markets where suppliers cannot directly utilize used goods for practicing intertemporal price discrimination and where transaction costs of resales are negligible, the threat of cannibalization of new goods by used goods becomes significant. We examine conditions under which it is optimal for suppliers to operate in...

摘要：This paper addresses the understudied issue of how individually held expertise in information systems development (ISD) teams results in creativity at the team level during the development process. We develop the idea that team creativity results primarily from integration of individually held expertise of team members at the team level. We further propose the quality of intrateam relationships and knowledge complementarities that align the work of individual team members at the project level ...

摘要：Knowledge management to facilitate the creation, storage, transfer, and application of knowledge in organizations has received wide attention in practice and research in the past several years. Often cited as a significant challenge in knowledge management practices is the issue of organizational culture. Although many studies raise the issue of organizational culture's influence on knowledge management success, few investigate the way in which this influence manifests itself. This paper aims ...

摘要：Convergence (i.e., mutual understanding) between an organization's CEO and CIO is critical to its efforts to successfully exploit information technology. Communication theory predicts that greater communication frequency and channel richness lead to more such convergence. A postal survey of 202 pairs of CEOs and CIOs investigated the effect of communication frequency and channel richness on CEO/CIO convergence, as well as the effect of convergence on the financial contribution of information s...

摘要：Vertical IS standards prescribe data structures and definitions, document formats, and business processes for particular industries, in contrast to generic information technology (IT) standards, which concern IT characteristics applicable to many industries. This paper explores the potential industry structure effects of vertical information systems (IS) standards through a case study of the U.S. home mortgage industry. We review theoretical arguments about the potential industry structure eff...

摘要：Information overload often hinders knowledge discovery on the Web. Existing tools lack analysis and visualization capabilities. Search engine displays often overwhelm users with irrelevant information. This research proposes a visual framework for knowledge discovery on the Web. The framework incorporates Web mining, clustering, and visualization techniques to support effective exploration of knowledge. Two new browsing methods were developed and applied to the business intelligence domain: We...

摘要：From the social network perspective, this study explores the ontological structure of knowledge sharing activities engaged in by researchers in the field of information systems (IS) over the past three decades. We construct a knowledge network based on coauthorship patterns extracted from four major journals in the IS field in order to analyze the distinctive characteristics of each subfield and to assess the amount of internal and external knowledge exchange that has taken place among IS rese...

摘要：Many argue that offshoring is an inexorable trend, since a variety of information technology (IT) skills have become global commodities and they are vastly cheaper in other parts of the world. According to this view, most IT work would be drained from the United States to overseas locations. However, the loss of jobs to offshoring has increased pressure to impose restrictions. On the supply side, as IT salaries in outsourcing vendor nations increase, they become less attractive for offshoring....

摘要：Investments in information technology (IT) have become crucial for firms to improve the quality of their products and services. Typically, IT cost for the same performance level declines over time. In a competitive market, a decline in IT cost over time provides a cost advantage to the later entrant, making the early entrant's investment decision problem challenging. In this paper, we study the problem of strategic IT investments in the declining cost scenario using a sequential duopoly model....
