摘要：This paper presents analytical, computational, and empirical analyses of strategies for intelligent bid formulations in online auctions. We present results related to a weighted-average ascending price auction mechanism that is designed to provide opaque feedback information to bidders and presents a challenge in formulating appropriate bids. Using limited information provided by the mechanism, we design strategies for software agents to make bids intelligently. In particular, we derive analyt...

摘要：This paper investigates the practice-based learning dynamics that emerge among peers who share occupational practices but do not necessarily work with each other or even know each other because of geographical or organizational distance. To do so, it draws on the literatures on situated learning, networks of practice, and information infrastructures, and on insights from a longitudinal case study of the implementation of a Web-based information system used by people working in the field of env...

摘要：The information systems (IS) literature suggests that by lowering coordination costs, information technology (IT) will lead to an overall shift towards more use of markets. Empirical work in this area provides evidence that IT is associated with a decrease in vertical integration (VI). Economy-wide data, however, suggests that over the last 25 years the average level of VI has, in fact, increased. This paper studies this empirical anomaly by explicating the moderating impact of two measures of...

摘要：Outsourcing of information technology (IT) services has received much attention in the information systems (IS) literature. However, considerably less attention has been paid to actual contract structures used in IT outsourcing (ITO). Examining contract structures yields important insights into how the contracting parties structure the governance provisions and the factors or transaction risks that influence them. Based on insights from prior literature, from practicing legal experts, and thro...

摘要：Model-based decision support systems (DSS) improve performance in many contexts that are data-rich, uncertain, and require repetitive decisions. But such DSS are often not designed to help users understand and internalize the underlying factors driving DSS recommendations. Users then feel uncertain about DSS recommendations, leading them to possibly avoid using the system. We argue that a DSS must be designed to induce an alignment of a decision maker's mental model with the decision model emb...
