[Show abstract][Hide abstract] ABSTRACT: Measuring peer influence in social networks is an important business and policy question that has become increasingly salient with the development of globally interconnected ICT networks. However, in spite of the new data sources available today, researchers still face many of the same measurement challenges that have been present in the literature for over four decades: homophily, reflection and selection problems, identifying the source of influence, and determining pre-existing knowledge. The goal of this paper is to develop an empirical approach for measuring information diffusion and discovery in online social networks that have these measurement challenges. We develop such an approach and apply it to data collected from 4,000 users of an online music community. We show that peers on such network significantly increase music discovery. Moreover, we demonstrate how future research can use this method to measure information discovery and diffusion using data from other online social networks.

[Show abstract][Hide abstract] ABSTRACT: User generated content is being recognized as part of the value proposition of e-commerce organizations. To make available fresh content on topics, one needs to understand how individuals consider existing contributions in their decision to contribute. This study develops and tests three hypotheses based on a survey and archival data of 235 contributors of reviews at Amazon.com. Results from a LISREL analysis indicate that those with greater self-perceived competence tend to submit content on topics with fewer existing contributions. On the other hand, those with higher social adjustive motive toward others in general tend to contribute on topics where there are many existing contributions. In contrast, people for whom the social adjustive motive toward specific others is salient are equally likely to contribute on topics with few and many existing contributions. These findings suggest ways for site administrators to ensure a balanced coverage across topics by addressing these individual and social factors.
[Show abstract][Hide abstract] ABSTRACT: Enabled by the Internet-Web compound, co-creation of value by consumers has emerged as a major force in the marketplace. In sponsored co-creation, which takes place at the behest of producers, the activities of consumers drive or support the producers' business models. Autonomous co-creation is a wide range of consumer activities that amount to consumer-side production of value. Thus, individuals and communities have become a significant, and growing, productive force in e-commerce. To recognize co-creation, so broadly understood, as a fundamental area of e-commerce research, it is necessary to attain an integrated research perspective on this greatly varied, yet cohering, domain. The enabling information technology needs to be developed to suit the context. Toward these ends, the paper analyzes the intellectual space underlying co-creation research and proposes an inclusive taxonomy of Web-based co-creation, informed both by the extant multidisciplinary research and by results obtained in the natural laboratory of the Web. The essential directions of co-creation research are outlined, and some promising avenues of future work discussed. The taxonomic framework and the research perspective lay a foundation for the future development of co-creation theory and practice. The certainty of turbulent developments in e-commerce means that the taxonomic framework will require ongoing revision and expansion, as will any future framework. [ABSTRACT FROM AUTHOR]
