摘要：Many software firms, especially mobile app providers, offer perpetually free basic products to users, but premiums are charged for access to the additional features or functionalities. While the free offering helps capture potential customers, it might cannibalize the sales of premium goods or services. This paper adopts a game theoretical approach to examine the impact of free offering on the competition between two firms in the presence of network effects. The firms can either offer a free c...

摘要：It is by now almost accepted as a stylized fact that offering deal promotion (such as via Groupon or LivingSocial) deteriorates local merchants' online reputations (e.g., the average of Yelp review ratings). However, in this paper we show that the stylized fact is not true in certain circumstances. We theorize that the valence and volume of prior reviews can play an important moderating role in the effect of deal promotion. Empirically, we show that restaurants with a relatively low prior aver...

摘要：Motivated by the rise of social media platforms that achieve a fusion of content and community, we consider the role of word-of-mouth communications (WOM) structured through a network. Using a data set from YouTube, we examine how cascades of WOM interactions enhance the popularity of videos. We first estimate the impact of channel influence and other network parameters in initiating WOM communications. The probit estimation considers the selection effect in videos that are likely to be associ...

摘要：Though aesthetics is generally acknowledged as an important aspect of website design, extant information systems (IS) research on web user experience has rarely studied what affects website aesthetics and how aesthetics influences users' perceptions of the website and the organization behind the website. In this paper, we synthesize prior literature from different academic domains and propose users' perceived quality of five design elements (i.e., unity, complexity, intensity, novelty, and int...

摘要：With the broad reach of the Internet, online users frequently resort to various word-of-mouth (WOM) sources, such as online user reviews and professional reviews, during online decision making. Although prior studies generally agree on the importance of online WOM, we have little knowledge of the interplay between online user reviews and professional reviews. This paper empirically investigates a mediation model in which online user reviews mediate the impact of professional reviews on online ...

摘要：We investigate the effectiveness of three types of IT-enabled cognitive stimulation tools for enhancing creative problem solving: mind mappers, process guides, and stimuli providers. Based on the dual pathway to creativity models, the authors examine the extent to which these tools are capable of stimulating individuals to explore their knowledge base more deeply (i.e., the persistence pathway) and more broadly (i.e., the flexibility pathway) and, hence, help to produce more novel ideas. In a ...

摘要：Fast-paced environmental changes require that managers quickly sense opportunities for organizational innovation. Information systems (IS) that support business intelligence and analytics help managers access and analyze data from various sources, thereby providing insight into potential opportunities. Building on the dynamic managerial capability perspective, we investigate the extent to which two managerial IS use behaviors-routine use and innovative use-influence a manager's volume and dive...

摘要：A growing trend to simultaneously insource and outsource the same information technology (IT) activities (concurrent IT sourcing) has not yet received research attention. Although it is widespread and recent empirical studies have detected that in-house IT can complement IT outsourcing, when and how concurrent IT sourcing pays off is not yet understood. This study introduces the notion of concurrent IT sourcing. It then develops two interrelated ideas: concurrent IT sourcing simultaneously enh...

摘要：In order to motivate individuals to share their knowledge in online communities, the use of extrinsic rewards and goals is a typical approach. However, extrinsic motivation may have unintended consequences. Although past studies have examined the direct effect of extrinsic motivation on intrinsic motivation, no research to date has investigated how extrinsic motivation moderates the impact of intrinsic motivation on knowledge sharing, or how the effect of extrinsic motivation on intrinsic moti...
