摘要：We investigate whether greater market competition improves or inhibits the ability of feedback systems in Internet markets to deliver trust and trustworthiness to the marketplace. Our investigation is grounded in the theory of signaling from information economics. Using methods from experimental economics, we create a laboratory online market where sellers face a moral hazard. We manipulate the level of market competition and the nature of the social network behind the feedback system and stud...

摘要：Information technology (IT) adoption research recognizes theoretical limitations in discerning if and when user behavior results from perceived external influences or from personal volition. A clear understanding of this issue requires a precise distinction between mandatory and volitional behaviors. Consistent with organismic integration theory (OIT), this study situates the locus of user motivations inside the user. Drawing upon an endogenous view of behaviors, this research makes three key ...

摘要：Firms have been increasing their information technology (IT) security budgets significantly to deal with increased security threats. An examination of current practices reveals that managers view security investment as any other and use traditional decision-theoretic risk management techniques to determine security investments. We argue in this paper that this method is incomplete because of the problem's strategic nature-hackers alter their hacking strategies in response to a firm's investmen...

摘要：Information availability has increased consumers' informedness, the degree to which they know what is available in the marketplace, with precisely which attributes and at precisely what price. This informedness has altered the demand side of market behavior: customers now discount more heavily when comparable products are available from competitors and when products do not meet their wants, needs, cravings, and longings, but they no longer discount as heavily when purchasing unfamiliar product...

摘要：This research investigates the relationship between a manufacturer's use of information technology (IT) (particularly electronic procurement) and the number of suppliers in its supply chain. Will a manufacturer use more or fewer suppliers due to the increasing use of IT? Based on data from a sample of 150 U.S. manufacturers, we find no direct relationship between e-procurement and number of suppliers at the aggregate level. However, when we distinguish the type of goods purchased, we find that...

摘要：Classical negotiation models are weak in supporting real-world business negotiations because these models often assume that the preference information of each negotiator is made public. Although parametric teaming methods have been proposed for acquiring the preference information of negotiation opponents, these methods suffer from the strong assumptions about the specific utility function and negotiation mechanism employed by the opponents. Consequently, it is difficult to apply these learnin...

摘要：As organizations increasingly utilize Web-based technologies to support customers better, trust in decision support technologies has emerged as an important issue in online environments. In this study, we identify six reasons users trust (or do not trust) a technology in the early stages of its use by extending the theories of trust formation in interpersonal and organizational contexts to that of decision support technologies. We study the particular context of decision support technologies f...

摘要：Real options analysis is an important but costly tool for valuing many information technology (IT) investments. As a low-cost substitute for real options-based methods, firms often depend on managerial intuition, which sometimes approximates real options-based valuations and sometimes does not. Making good choices about how to value IT investments requires an understanding of why, and therefore when, intuitive judgment is more or less likely to be consistent with real options-based valuations....

摘要：The diffusion of innovation theory is deployed to investigate the global assimilation of collaborative information technologies (CITs). Based on the concepts of IT acquisition and utilization, an assimilation framework is presented to highlight four states (limited, focused, lagging, and pervasive) that capture the assimilation of conferencing and groupware CITs. Data collected from 538 organizations in the United States, Australia, Hong Kong, Norway, and Switzerland are aggregated and analyze...
