摘要：Based on the wisdom of the crowd effect, consumer-generated online reviews are supposed to help consumers make more accurate product evaluations. However, the large amount of information in the reviews, coupled with conflicting opinions, can make it difficult for consumers to identify and consider those attributes relevant to their decision. Thus, while online product reviews are generally believed to empower consumers, we suggest that they may have swaying effects in that attribute preference...

摘要：With the increasing popularity of product recommendation networks in e-commerce, researchers and practitioners are eager to understand how they can strategically manage product assortments through the manipulation of such networks to drive demand. We examine product recommendation networks in e-commerce to investigate how the demand of a product is influenced by product network attributes in terms of network diversity and network stability. We also examine whether the demand of a product is in...

摘要：In this paper, we estimate the impact of enforcing the Convention on Cybercrime (COC) on deterring distributed denial of service (DDOS) attacks. Our data set comprises a sample of real, random spoof-source DDOS attacks recorded in 106 countries in 177 days in the period 2004-2008. We find that enforcing the COC decreases DDOS attacks by at least 11.8 percent, but a similar deterrence effect does not exist if the enforcing countries make a reservation on international cooperation. We also find ...

摘要：Many companies have adopted technology driven social learning platforms such as social customer relationship management (crowdsourcing customer support) to support knowledge sharing among customers. A number of these self-evolving, online customer support communities have reported the emergence of a coreperiphery knowledge sharing network structure. In this study, we investigate why such a structure emerges and its implications for knowledge sharing within the community. We propose a dynamic s...

摘要：Social media-based expert blogs are a crucial and credible online information source for consumers, yet little is known about the role of expert blogs for general consumer brand perceptions that bestow long-term value for the firm. On the basis of a novel dataset with 7,871 brand-day observations of over 131,000 expert blogs on major brands in the PC industry, this study reveals how expert blogs may act as a quality signal leading general consumers' perceptions of rival brands. Our analyses re...

摘要：Supporters of net neutrality have often argued that more competition among Internet service providers (ISPs) is beneficial for an open Internet and that the market power of the ISPs lies at the heart of the net neutrality debate. However, the joint effects of the competition among ISPs and among content providers (CPs) have yet to be examined. We study the critical linkage between ISP competition and CP competition, as well as its policy implications. We find that even under competitive pressu...

摘要：Clinical intelligence about a patient's risk of future adverse health events can support clinical decision making in personalized and preventive care. Healthcare predictive analytics using electronic health records offers a promising direction to address the challenging tasks of risk profiling. Patients with chronic diseases often face risks of not just one, but an array of adverse health events. However, existing risk models typically focus on one specific event and do not predict multiple ou...

摘要：Prediction markets provide a promising approach for future event prediction. Most existing prediction market approaches are based on auction mechanisms. Despite their theoretical appeal and success in various application settings, these mechanisms suffer from several major drawbacks. First, opinions from experts and amateurs are treated equally. Second, continuous attention from participants is assumed. Third, such mechanisms are subject to various forms of market manipulation. To alleviate th...

摘要：Drawing from a total rewards perspective, we introduce three work outcomes (namely, extrinsic, social, and intrinsic) as determinants of person-organization (PO) and person-job (PJ) fit perceptions of new IT employees. Gender is proposed as a moderator of the relationships between valuations of different work outcomes and fit perceptions. We found support for our model in three separate studies. In each of the studies, we gathered data about the work outcomes and fit perceptions of IT workers....
