摘要：We contribute to the shifting discourse in the literature on information system use, towards context-specific (rather than general) theories and effective use (rather than just use). Organizations are under great pressure to use information systems effectively but they have few theories to turn to for insights. Motivated by this need, we propose an approach for developing context-specific theories of effective use. The approach suggests that effective use can be theorized by: (1) understanding...

摘要：Should a monopolistic vendor adopt the selling model or the leasing model for information goods or services? We study this question in the context of consumer valuation depreciation. Using a two-period game-theoretic model, we consider two types of consumer valuation depreciation for information goods or services: vintage depreciation and individual depreciation. Vintage depreciation assumes that a good or service loses some of its appeal to consumers as it becomes dated, and this effect persi...

摘要：Based on an exploratory multiple-case study in two platform ecosystems, we develop a process theory that explains how and why different ways of practicing ecosystem- wide governance are more or less successful in navigating the tension between cocreated value and governance costs. Our process theory shows that how ecosystem-wide rules and values are practiced considerably varies and changes over time. Initially, governance practices follow ecosystem-wide rules; if and how practices shift towar...

摘要：There are many contexts in which an everybody else is doing it attitude is relevant. We evaluate the impact of this attitude in a multithreshold public goods game. We use a lab experiment to study the role of providing information about contribution behavior to targeted subsets of individuals, and its effect on coordination. Treatments include one in which no information is provided and three other treatments, i.e., where information is provided to a random sample of subjects; to those whose c...

摘要：Health information technology has increased accessibility of health and medical data and benefited medical research and healthcare management. However, there are rising concerns about patient privacy in sharing medical and healthcare data. A large amount of these data are in free text form. Existing techniques for privacy-preserving data sharing deal largely with structured data. Current privacy approaches for medical text data focus on detection and removal of patient identifiers from the dat...

摘要：We empirically examine the impact of expanded product variety on demand concentration using large data sets from the movie rental industry as our test bed. We find that product variety is likely to increase demand concentration, which goes against the long tail effect theory predicting that demand will become less concentrated on hit products because of expanded product variety. We further provide evidence that this finding is not due to introducing many low-selling niche products, as the intu...

摘要：Although control beliefs (CBs) can represent many different types of controls, information systems researchers have focused primarily on CBs related to technical compatibility, resource availability, and computer self-efficacy. More recent research has recognized that co-worker advice, which represents situated and improvised learning, can also be an important factor that can enable or impede system use. In addition, because advice from co-workers represents the social context by which the imp...

摘要：The Internet has presumably created a level playing field that allows any service provider across the globe to compete for contracts on online outsourcing platforms for information technology (IT) services. In this paper, we empirically examine (a) how country (language, time zone, cultural) differences and the country's IT development affect buyers' selection of service providers in online outsourcing platforms; and (b) how the reputation of service providers moderates the proposed effects of...

摘要：We study the strategic benefits of mergers and acquisitions (M&As) when competing information technology vendors sell different generations of the same product with different quality. We assume the newproduct arrives unexpectedly when an installed base of the old product exists. We show that the combination of consumers' purchase history and heterogeneity leads to new demand complexity that gives rise to innovative product strategies. We find that shelving the old product is an important motiv...
