摘要：Online storage service providers grant a way for companies to avoid spending resources on maintaining their own in-house storage infrastructure and thereby allowing them to focus on their core business activities. These providers, however, follow a fixed, posted pricing strategy that charges the same price in each time period and thus bear all the risk arising out of demand uncertainties faced by their client companies. We examine the effects of providing a spot market with dynamic prices and ...

摘要：This paper analyzes interactions between a firm that seeks to discriminate between normal users and hackers that try to penetrate and compromise the firm's information assets. We develop an analytical model in which a variety of factors are balanced to best manage the detection component within information security management. The approach not only considers conventional factors such as detection rate and false-positive rate, but also factors associated with hacker behavior that occur in respo...

摘要：The information systems (IS) literature has focused considerable research on IS resistance, particularly in the health-care industry. Most of this attention has focused on the impact of IS resistance on systems' initial implementation, but little research has investigated whether and how post-adoption resistance affects performance. We focus on a particular type of post-adoption resistance, which we call IS avoidance, to identify situations in which individuals avoid working with adopted IS de...

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：Prior studies on product recommendation agents (RAs) have been based on the effort-accuracy perspective in which the amount of effort required to make a decision and the accuracy of such decisions are two dominant antecedents of user acceptance of RAs. The current study extends the effort-accuracy perspective by considering trade-off difficulty, a type of negative emotion that arises when attainment of one's goals is blocked by the attainment of other goals; consequently, one must make trade-o...

摘要：Many successful open-source projects have been developed by programmers who were employed by firms but worked on open-source projects on the side because of economic incentives like career improvement benefits. Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on thes...

摘要：Information specialists in enterprises regularly use distributed information retrieval (DIR) systems that query a large number of information retrieval (IR) systems, merge the retrieved results, and display them to users. There can be considerable heterogeneity in the quality of results returned by different IR servers. Further, because different servers handle collections of different sizes and have different processing and bandwidth capacities, there can be considerable heterogeneity in thei...

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 ...
