摘要：Existing scholarship on social media provides us with important but incomplete insights regarding how people rely upon social media as they work. Scholarship so far focuses on social media as technologies that enable and constrain people to do certain things. This study proposes a perspective on social media for work that views them not only as technologies that enable people to do certain things, but also as contexts with emerging norms and roles in which people participated. As they do so, p...

摘要：We investigate whether revenue-maximizing auctioneers selling heterogeneous items will allow for combinatorial bidding in the presence of auctioneer competition. We compare the choice of auction format by two competing auctioneers with that of a single auctioneer. Bidders are heterogeneous in their demands, with some having synergies for items. We find that, even if a single auctioneer offers a combinatorial auction, competing auctioneers in a comparable setting will not. Instead, the competin...

摘要：This paper advances the understanding of the information systems (IS) discipline by developing a multidimensional conceptualization of the discipline's intellectual diversity. It also provides an empirical analysis of the intellectual diversity exhibited by the full set of articles published in Information Systems Research (ISR) over the last 10 years. We categorize IS intellectual diversity into four intellectual dimensions of IS research-namely, domain-topic, level of phenomenon, type of con...

摘要：Seller and product authentication problems are inherent in online markets, particularly in the time-constrained setting of online auctions. Although trust-building mechanisms such as seller feedback can mitigate these problems, they are retrospective, providing information about a transaction only after it is completed. Also, they have only indirect effects on buyers' trust in sellers because they are not based on direct interactions between a trustor (buyer) and a trustee (seller). On the oth...

摘要：Humans are increasingly interacting in and operating their daily lives through structured digital and virtual environments, mainly through apps that provide media for sharing photos, messaging, gaming, collaborating, or video watching. Most of these digital environments are offered under freemium pricing to facilitate adoption and network effects. In these settings, users' early social interaction and experience often have a substantial impact on their longer term behavior. On this background,...

摘要：We study the design of core-selecting payment rules for combinatorial auctions, a challenging setting where no strategyproof rules exist. We show that the rule most commonly used in practice, the Quadratic rule, can be improved on in terms of efficiency, incentives, and revenue. We present a new computational search framework for finding good mechanisms, and we apply it toward a search for good core-selecting rules. Within our framework, we use an algorithmic Bayes-Nash equilibrium solver to e...

摘要：Online matching platforms require new approaches to market design because firms can now control many aspects of the search and interaction process through various IT-enabled features. Although choice capacity-the number of candidates a user can view and select-is a key design feature of online matching platforms, its effect on engagement and matching outcomes remains unclear. We examine the effect of different choice capacities on the number of choices and matches made on a platform by conduct...

摘要：The current information systems (IS) literature treats information technology (IT) ambidexterity as a single aggregated construct, assuming perfect balance or simultaneously strong IT exploration and exploitation. Taking a different perspective, we propose that IT ambidexterity can be achieved through a proportional balance between its two dimensions, and the optimal balance depends on the specific context. Based on matchedpair data from a field survey of business and IT executives, we find a ...

摘要：Established process steps for design science research have not addressed the usability of technology artifacts beyond the original research setting. Building on what is already known about generalizing a theory from one setting to another and the idea of an artifact as the interface between an inner environment and outer environment put forth by Nobel Prize-winning social scientist Herbert Simon, we propose a procedure for generalizing an information systems (IS) artifact from one setting to a...
