摘要：In peer-to-peer (P2P) media distribution, users obtain content from other users who already have it. This form of decentralized product distribution demonstrates several unique features. Only a small fraction of users in the network are queried when a potential adopter seeks a file, and many of these users might even free-ride, i.e., not distribute the content to others. As a result, generated demand might not always be fulfilled immediately. We present mixing models for product diffusion in P...

摘要：Enterprise systems software (ESS) is a multibillion dollar industry that produces systems components to support a variety of business functions for a widerange of vertical industry segments. Even if it forms the core of an organization's information systems (IS) infrastructure, there is little prior IS research on the competitive dynamics in this industry. Whereas economic modeling has generally provided the methodological framework for studying standards-driven industries, our research employ...

摘要：The Internet and related information technologies are transforming the distribution of product sales across products, and these effects are likely to grow in coming years. Both the Long Tail and the Superstar effect are manifestations of these changes, yet researchers lack consistent metrics or models for integrating and extending their insights and predictions. In this paper, we begin with a taxonomy of the technological and nontechnological drivers of both Long Tails and Superstars and then ...

摘要：Outsourcing of software development allows a business to focus on its core competency and take advantage of vendors' technical expertise, economies of scale and scope, and their ability to smooth labor demand fluctuations across several clients. However, contracting a software project to an outside developer is often quite challenging because of information asymmetry and incentive divergence. A typical software development contract must deal with a variety of interrelated issues such as the qu...

摘要：A growing number of vendors are using a sequence of online auctions to sell large inventories of identical items. Although bidding strategies and bidder behavior in single auctions have been extensively studied, limited research exists on bidding in sequential auctions. We seek to explain how bidders in such an environment learn from the information, and form and update their willingness to pay (WTP). Using a large data set from an online auction retailer, we analyze the evolution of the bidde...

摘要：Researchers in competitive dynamics have demonstrated that firms that carry out intense, complex, and heterogeneous competitive actions exhibit better performance. However, there is a need to understand factors that enable firms to undertake competitive actions. In this study, we focus on two antecedents of competitive behavior of firms: (1) access to network resources and (2) use of information technology (IT). We argue that while network structure provides firms with the opportunity to tap i...

摘要：Prior studies investigating business-to-consumer e-commerce have focused predominantly on online shopping by individuals on their own, although consumers often desire to conduct their shopping activities with others. This study explores the important, but seldom studied, topic of collaborative online shopping. It investigates two design components that are pertinent to collaborative online shopping support tools, namely, navigation support and communication support. Results from a laboratory e...

摘要：Organizations are increasingly engaged in competitive dynamics that are enabled or induced by information technology (IT). A key competitive dynamics question for many organizations is how to build a competitive advantage in turbulence with digital IT systems. The literature has focused mostly on developing and exercising dynamic capabilities for planned reconfiguration of existing operational capabilities in fairly stable environments with patterned waves, but this may not always be possible,...

摘要：Firms are increasingly dependent on external resources and are establishing portfolios of interorganizational relationships (IRs) to leverage external resources for competitive advantage. However, the systems of information technology (IT) and process capabilities that firms should develop to manage IR portfolios dynamically are not well-understood. In order to theorize how key structural IT capabilities (IT integration and IT reconfiguration) and competitive process capabilities (process alig...

摘要：Since the inauguration of information systems research (ISR) two decades ago, the information systems (IS) field's attention has moved beyond administrative systems and individual tools. Millions of users log onto Facebook, download iPhone applications, and use mobile services to create decentralized work organizations. Understanding these new dynamics will necessitate the field paying attention to digital infrastructures as a category of IT artifacts. A state-of-the-art review of the literatu...
