摘要：Firms have considered various forms of incentives for writing reviews, including the use of extrinsic rewards to attract reviewers. Building on this literature, we study the implications of monetary incentives on online reviews in the context of a natural experiment, where one review platform suddenly began offering monetary incentives for writing reviews. We refer to this as the treated platform. Along with data from Amazon.com and using the difference-in-differences approach, we compare the ...

摘要：Although many researchers in information systems and marketing have studied the effect of product reviews on sales, few have looked at their effect on product returns. We hypothesize that, by reducing product uncertainty, product reviews affect the probability of product returns. We elaborate this hypothesis starting with an analytical model that examines how changes in valence and precision of information from product reviews influence the purchase and return probabilities of risk-averse, but...

摘要：While the growth of the mobile apps market has created significant market opportunities and economic incentives for mobile app developers to innovate, it has also inevitably invited other developers to create rip-offs. Practitioners and developers of original apps claim that copycats steal the original app's idea and potential demand, and have called for app platforms to take action against such copycats. Surprisingly, however, there has been little rigorous research analyzing whether and how ...

摘要：This study examines coordination issues that occur between the marketing department and the information technology (IT) department in electronic retail settings. We consider a marketing department that is responsible for choosing the level of advertising to generate traffic to the firm's website and an IT department that is responsible for choosing IT capacity to provide web visitors a satisfactory experience. The focus here is to examine how duopolistic advertising competition among firms can...

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...
