摘要：Research on online content diffusion is vast but has rarely examined contextual factors, including the influence of online sharing mechanisms, such as social plugins (e.g., Facebook's Like button), on online social networks (OSNs). While these mechanisms generally enable the content flow between senders and recipients, they vary in protecting users' social and institutional privacy on OSNs. Additionally, sharing mechanisms might differ with respect to their labeling (e.g., positive versus neut...

摘要：Social-networking functions are increasingly embedded in online rating systems. These functions alter the rating context in which consumer ratings are generated. In this paper, we empirically investigate online friends' social influence in online book ratings. Our quasi-experimental research design exploits the temporal sequence of social-networking events and ratings and offers a new method for identifying social influence while accounting for the homophily effect. We find that rating similar...

摘要：Digital platforms can be opened in two ways to promote innovation and value generation. A platform owner can open access for third-party participants by establishing boundary resources, such as APIs and an app store, to allow complements to be developed and shared for the platform. Furthermore, to foster cooperation with the complementors, the platform owner can use an open-source license boundary resource to open and share the platform's core resources. However, openness that is too wide rend...

摘要：In the software industry, commercial open-source software vendors have recognized that providing services to help businesses derive greater value in the implementation of open source-based systems can be a profitable business model. Moreover, society may greatly benefit when software originators choose an open-source development strategy as their products become widely available, readily customizable, and open to community contributions. In this study, we present an economic model to study how...

摘要：Recommender systems are an integral part of the online retail environment. Prior research has focused largely on computational approaches to improving recommendation accuracy, and only recently researchers have started to study their behavioral implications and potential side effects. We used three controlled experiments, in the context of purchasing digital songs, to explore the willingness-to-pay judgments of individual consumers after being shown personalized recommendations. In Study 1, we...

摘要：We study a novel privacy concern, i.e., peer disclosure of sensitive personal information in online social communities. We model peer disclosure as the imposition of a negative externality on other people. Our model encompasses the benefits of posting information, positive externalities in the form of recognition and entertainment benefits due to others' sharing of information, and heterogeneous privacy preferences. We find that regulation of peer disclosure is necessary. We consider two candi...

摘要：As organizations increasingly use digital platforms to facilitate innovation, researchers are seeking to understand how platforms shape business practices. Although extant literature offers important insights into platform management from a platform-owner perspective, we know little about how organizations manage industry platforms provided by external parties to generate opportunities and overcome challenges in relation to their infrastructure and work processes. As part of larger ecosystems,...

摘要：Recently, mobile applications have offered users the option to share their location information with friends. Using data from a major location-based social networking application in China, we estimate an empirical model of restaurant discovery and observational learning. The unique feature of repeat customer visits in the data allows us to examine observational learning in trials and repeats and to separate it from non-informational confounding mechanisms, such as homophily, using a novel test...

摘要：In the past decade, we have witnessed the growing importance of management responses to online reviews on digital platforms. In this study, we examine the impact of online management responses on business performance and their spillover effect on nearby businesses. By adopting multiple causal identification strategies to address the issue of self-selected responses, we find that the responses by a business owner play a significant role in the performance of the focal business as well as in the...

摘要：Multihoming, the decision to design a complement to operate on multiple platforms, is becoming increasingly common in many platform markets. Perceived wisdom suggests that multihoming is beneficial for complement providers as they expand their market reach, but it reduces differentiation among competing platforms as the same complements become available on different platforms. We argue that complement providers face trade-offs when designing their products for multiple platform architectures-t...
