摘要：Virtual communities are a significant source of information for consumers and businesses. This research examines how users value virtual communities and how virtual communities differ in their value propositions. In particular, this research examines the nature of trade-offs between information quantity and quality, and explores the sources of positive and negative externalities in virtual communities. The analyses are based on more than 500,000 postings collected from three large virtual inve...

摘要：It can be expensive to acquire the data required for businesses to employ data-driven predictive modeling-for example, to model consumer preferences to optimize targeting. Prior research has introduced active-learning policies for identifying data that are particularly useful for model induction, with the goal of decreasing the statistical error for a given acquisition cost (error-centric approaches). However, predictive models are used as part of a decision-making process, and costly improvem...

摘要：Researchers have widely postulated that the adoption of information technology (IT) products enhances global competitiveness and production efficiency as successful technological innovation replaces and improves traditional inputs and modes of production. This study suggests that when IT products are traded across borders, IT investment in an economy has a positive influence on the productivity of its import partner country. We provide empirical evidence for the positive effect of global IT di...

摘要：The ability to collect and disseminate individually identifiable microdata is becoming increasingly important in a number of arenas. This is especially true in health care and national security, where this data is considered vital for a number of public health and safety initiatives. In some cases legislation has been used to establish some standards for limiting the collection of and access to such data. However, all such legislative efforts contain many provisions that allow for access to in...

摘要：This paper examines the antecedents and consequences of Internet use in the procurement process. Drawing upon the resource-based view (RBV) of the firm and the technology, organization, and environment framework, we develop an integrative model that examines the antecedents and consequences of Internet use in two stages-the search stage and the order initiation and completion (OIC) stage-of the procurement process. The model enables us to deconstruct both the usage and the performance aspects ...

摘要：variety of information technology (IT) artifacts, such as those supporting reputation management and digital archives of past interactions, are commonly deployed to support online communities. Despite their ubiquity, theoretical and empirical research investigating the impact of such IT-based features on online community communication and interaction is limited. Drawing on the social psychology literature, we describe an identity-based view to understand how the use of IT-based features in onl...
