摘要：This paper provides a novel theoretical angle and robust empirical evidence demonstrating that the auction duration and item description length are two essential auction design parameters that can function as a screening mechanism for bidder quality on online service outsourcing platforms. These outsourcing platforms use buyer-determined reverse auctions to find providers of services (primarily IT services). Using data from a major online outsourcing platform that connects buyers with bidders,...

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：Strategic sellers on some online selling platforms have recently been using a conditional-rebate strategy to manipulate product reviews under which only purchasing consumers who post positive reviews online are eligible to redeem the rebate. A key concern for the conditional rebate is that it can easily induce fake reviews, which might be harmful to consumers and society. We develop a microbehavioral model capturing consumers' review-sharing benefit, review-posting cost, and moral cost of lyin...

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：Informative online ratings enable digital platforms to reduce the search cost for buyers to find good sellers. However, rating inflation, a phenomenon in which average rating increases and rating variance across listings decreases, threatens the informativeness of ratings. We empirically identify the consequences of rating inflation by conducting a quasi-experiment with a digital platform that exogenously changed its rating display rule in a treated neighborhood, which resulted in rating infla...

摘要：How can information technology (IT) help hospitals gain and sustain reputation in the media? Combining signaling theory and technology frames, we examine if, how, and to what extent IT investments over time shape three facets of reputation: generalized favorability, being known, and being known for something. In accessing healthcare services, most patients are unable to assess a hospital's quality of care directly. Faced with such information asymmetries, patients tend to consider a hospital's...

摘要：Consumer profiling has become one of the most common practices on online trading platforms. Many platforms strive to obtain and implement technological innovations that allow them to understand and identify consumers' needs, and, thereafter, monetize this capability by charging sellers to present and/or sell their products or services based on consumers' interests. However, an interesting and relevant question arises in this context: Does the platform have an incentive to profile its buyers as...

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：We examine the productivity implications of external knowledge flows obtained through an internet-mediated discussion forum in which IT professionals help one another solve problems related to the implementation and use of enterprise software. We extend elements of the absorptive capacity (ACAP) framework that have not previously been studied in the information systems (IS) literature to a new context. Consistent with prior results from the IS literature, we first show that IT spillovers-acqui...
