摘要：We examine how social sharing of consumers' brand purchases affects brand competition in a market where different types of consumers, characterized by their distinct personal characteristics (i.e., personalities, hobbies, and lifestyles) and brand preferences (i.e., being loyal to one of two horizontally differentiated brands or neither), all desire accurate public perception of their true type. Social sharing of a consumer's brand purchase allows the public to infer the consumer's type, but s...

摘要：Topic modeling methods such as latent Dirichlet allocation (LDA) are powerful tools for analyzing massive amounts of textual data. They have been used extensively in information systems (IS) and business discipline research to identify latent topics for data exploration and as a feature engineering mechanism to derive new variables for analyses. However, existing topic modeling approaches are mostly unsupervised and only leverage textual data, while ignoring additional useful metadata often as...

摘要：Many of today's software systems are created by leveraging ecosystems consisting of heterogeneous complementors and hub firms. In fact, the reliance on ecosystems is prevalent in the enterprise resource planning (ERP) domain, where larger ERP vendors form collaborative relationships with smaller industry-specific vendors to co-create value for themselves and their customers. However, value creation and destruction processes are often intertwined. A key motivation for this study is to shed ligh...

摘要：We investigate the role of frictions in determining the efficiency and bidding behavior in a generalized second-price auction-the most preferred mechanism for sponsored-search advertisements. In particular, we take a twofold approach of Q-learning-based computational simulations in conjunction with human-subject experiments. We find that the lower valued advertisers (who do not win the auction) exhibit highly exploratory behavior. Moreover, we find the presence of market frictions moderates th...

摘要：As platform owners interact with end users and complementors, their demand side characteristics and performance affect the overall value creation of ecosystems. This research investigated how the emergence of popular complements on a mobile communication platform impacts the usage of other complementary products by the platform's end users and how platform owners can benefit from such demand spillovers. We identified two different forms of demand spillovers (i.e., backward and forward) and con...

摘要：Content providers in online social media platforms, particularly livestreaming, often switch content categories. Despite its uniqueness and importance, there is a dearth of academic research examining the unintended effects of providers' content switching. We study the direct and indirect spillover effects of content switching for livestreamers-individuals who broadcast content through livestreaming platforms. We propose a framework based on theories related to viewer flow and network effects ...

摘要：Online healthcare portals have become prevalent worldwide in recent years. One common formof a healthcare portal is the online consultation website, which provides a bridge between patients and doctors and reduces patients' time and cost when seeking healthcare services. Another form is the healthcare service appointment website, which facilitates offline visits for patients. Although nominally separate, the behaviors of the users (including patients and doctors) on these two types of websites...

摘要：Although digital platforms have become mainstream, there still remain some unanswered questions pertaining to managing platform ecosystems. One such unexplored question pertains to the effect of marquee sellers on the platform-marquee sellers arguably attract other sellers and buyers to the platform, thereby enhancing the platform's value. In this paper, we study how adding a marquee seller to a business-to-business (B2B) secondary-market platform for IT products affects other sellers, in term...

摘要：Although social media has helped online newspapers by allowing users to organically share articles, some have argued that it has cannibalized and hurt newspapers through reduced readership and diminished agenda-setting power. Motivated by these two opposing effects, it is critical to understand what affects the duality between sharing news articles on social media and reading the articles on news websites. Using rich click stream data on online news readership obtained from an English-language...

摘要：We study, using three sequential field experiments, collaborative problem solving in knowledge work enabled by information technology within the context of the customer support function in a leading high-technology firm. Experiment one examines the performance change after introducing a new collaborative problem-solving process, specifically whether the use of a team of experts across departments to solve problems can help reduce problem-solving costs. In addition to the extant process of supp...
