摘要：Price dispersion is an important indicator of market efficiency. Internet-based electronic markets have the potential to reduce transaction and search costs, thereby creating more efficient, frictionless markets, as predicted by theories in information economics. However, earlier work has reported significant levels of price dispersion on the Internet, which is in contrast to theoretical predictions. A key feature of the existing stream of work has been its use of posted prices to estimate pri...

摘要：We study agency problems that arise when prototypes are used for requirements assessment. The precision with which the prototype helps a client assess his requirements depends on (a) the type of prototype provided by the vendor and (b) the client's feedback effort. The vendor can provide either a neutral or nonneutral prototype: The nonneutral prototype influences the client towards one particular set of requirements that may not be the true requirement, and the neutral prototype allows the cl...

摘要：In this paper, we empirically investigate the impact of information technology (IT) investment on firm return and risk financial performance, emphasizing the moderating role of the firm boundary strategies of diversification and vertical integration. Our results indicate a sharp contrast between the direct and interactive effects of IT on both the return (profitability) and risk (variability of returns) dimensions. Although the direct effect of IT capital is to increase firm risk for a given l...

摘要：Although online retailers detail their privacy practices in online privacy policies, this information often remains invisible to consumers, who seldom make the effort to read and understand those policies. This paper reports on research undertaken to determine whether a more prominent display of privacy information will cause consumers to incorporate privacy considerations into their online purchasing decisions. We designed an experiment in which a shopping search engine interface clearly and ...

摘要：This paper aims to understand the influence of punishment and perceived justice on user compliance with mandatory information technology (IT) policies. Drawing on punishment research and justice theory, a research model is developed. Data collected from a field survey of enterprise resource planning (ERP) users are analyzed to test the proposed hypotheses. The results indicate that IT compliance intention is strongly influenced by perceived justice of punishment, which is negatively influenced...

摘要：Digital inequality, or unequal access to and use of information and communication technologies (ICT), is a severe problem preventing the socioeconomically disadvantaged (SED) from participating in a digital society. To understand the critical resources that contribute to digital inequality and inform public policy for stimulating initial and continued ICT usage by the SED, we drew on capital theories and conducted a field study to investigate: (1) the forms of capital for using ICT and how the...

摘要：The Internet is making a significant transition from primarily a network of desktop computers to a network variety of connected information devices such as personal digital assistants and global positioning system-based devices. On the other hand, new paradigms such as overlay networks are defining service-based logical architecture for the network services that make locating content and routing more efficient. Along with Internet2's proposed service-based routing, overlay networks will create...

摘要：Extant research considers the IT governance choice to be a trade-off between the cost-efficiency of centralization and the responsiveness provided by local information processing. This view predicts that firms tend to decentralize IT governance in more uncertain environments. We investigate this issue by studying the relationship between environmental uncertainty and IT infrastructure governance in a sample of business units from Fortune 1000 companies. The key proposition in this paper is tha...

摘要：Combinatorial auctions are used for the efficient allocation of heterogeneous goods and services. They require appropriate software platforms that provide automated winner determination and decision support for bidders. Several promising ascending combinatorial auction formats have been developed throughout the past few years based on primal-dual algorithms and linear programming theory. The ascending proxy auction and iBundle result in Vickrey payoffs when the coalitional value function satis...

摘要：Application service providers (ASP), who host and maintain information technology (IT) applications across the Internet, emerged as an innovation in the way IT services are delivered to client firms. In spite of many potential benefits of this model, ASPs experienced business failure and high rates of exit. Drawing on agency theory, we argue that the efficiency of contracting arrangements between ASPs and client organizations is an important determinant of ASP survival. We test this prediction...
