摘要：In the online word-of-mouth literature, research has consistently shown that negative reviews have a greater impact on product sales than positive reviews. Although this negativity effect is well documented at the product level, there is less consensus on whether negative or positive reviews are perceived to be more helpful by consumers. A limited number of studies document a higher perceived helpfulness for negative reviews under certain conditions, but accumulating empirical evidence suggest...

摘要：Online communities frequently create significant economic and relational value for community participants and beyond. It is widely accepted that the underlying source of such value is the collective flow of knowledge among community participants. We distinguish the conditions for flows of tacit and explicit knowledge in online communities and advance an unconventional theoretical conjecture: Online communities give rise to tacit knowledge flows between participants. The crucial condition for t...

摘要：Individuals' actions in online social contexts are growing increasingly visible and traceable. Many online platforms account for this by providing users with granular control over when and how their identity or actions are made visible to peers. However, little work has sought to understand the effect that a user's decision to conceal information might have on observing peers, who are likely to refer to that information when deciding on their own actions. We leverage a unique impression-level ...

摘要：It is not enough to get information technology (IT) users to adopt a secure behavior. They must also continue to behave securely. Positive outcomes of secure behavior may encourage the continuance of that behavior, whereas negative outcomes may lead users to adopt less-secure behaviors. For example, in the context of authentication, login success rates may determine whether users continue to use a strong credential or switch to less secure behaviors (e.g., storing a credential or changing to a...

摘要：Motivated by the pervasive discrepancy among the pricing schemes of data services, this paper investigates the selection of pricing metrics (variables) and the corresponding pricing plans. We construct a stylized model in which a monopoly data services seller faces heterogeneous consumers whose utilities depend on the usage and the connection speed. We examine three options for the seller to conduct the second-degree (indirect) price discrimination: by minutes, by gigabytes (Gigs), and by mega...

摘要：Emerging from rapid advances in digitization and technological capabilities is a new form of information systems development project: cyber projects. Cyber projects are complex, massive, and ambitious, often involving hundreds of academic, government, and industry professionals, requiring years of development, and costing millions of dollars. In our study, we examine how control is exercised in cyber projects. Based on a longitudinal study over eight years, we develop a process theory of the c...

摘要：To manage work interdependencies, online communities draw on a variety of arm's length coordination mechanisms offered by information technology platforms and associated practices. However, unresolved interdependencies remain that cannot be addressed by such arm's length mechanisms. These interdependencies reflect, for example, unidentified or emerging knowledge-based dependencies between the community members or unaccounted relationships between ongoing community tasks. At the same time, onli...

摘要：Based on our interactions with the key personnel of three different healthcare information exchange (HIE) providers in Texas, we develop models to study the sustainability of HIEs and participation levels in these networks. We first examine how heterogeneity among healthcare practitioners (HPs) (in terms of their expected benefit from the HIE membership) affects participation of HPs in HIEs. We find that, under certain conditions, low-gain HPs choose not to join HIEs. Hence, we explore several...

摘要：A core activity in information systems development involves building a conceptual model of the domain that an information system is intended to support. Such models are created using a conceptual-modeling (CM) grammar. Just as high-quality conceptual models facilitate high-quality systems development, high-quality CM grammars facilitate high-quality CM. This paper provides a new perspective on ways to improve the quality of the semantics of CM grammars. For many years, the leading approach to ...

摘要：Increasingly, new forms of organizing for knowledge production are built around self-organizing coproduction community models with ambiguous role definitions. Current theories struggle to explain how high-quality knowledge is developed in these settings and how participants self-organize in the absence of role definitions, traditional organizational controls, or formal coordination mechanisms. In this article, we engage the puzzle by investigating the temporal dynamics underlying emergent role...
