Abstract:
|
We study the effect of consumers’ online interactions on their product review behaviors. A popular form of users’ online interaction is the “subscription” model that gives priority to contents generated by the person subscribed to. Using a panel dataset from epinions.com, we examine how users’ product review behaviors evolve as their online followership – peers who are silent – grows. Our results have implications for research on word-of-mouth and user-generated content (UGC) sites in general.

Abstract:
|
In this paper, we present a novel randomized experiment that tests the existence of causal peer influence in the general population of a particular large-scale online social network. Both simple t-test and logistic regression indicate that user’s adoption of a product causes her online friends to pay for it and adopt it as well.

Abstract:
|
Contrary to Thomas Friedman’s Flat World hypothesis, here, we argue that the world is by no means flat, as distance continues to exist along dimensions other than the physical. Many online marketplaces today offer participants the opportunity to engage in economic exchange with others the world over. As a result, the differences between parties are often striking. Bearing this in mind, we explore the impact of cultural differences on lending on the world’s largest micro-finance website, Kiva.org. Leveraging an aggregate dataset of country-to-country lending, incorporating three million lending actions over a five-year period, we find that cultural differences are negatively associated with lending and, interestingly, that this association is decreasing in physical distance (we interpret this as an awareness effect). We consider the implications of this finding for the purveyors of globalized online marketplaces, making recommendations regarding information presentation and the application of institutional trust mechanisms.

Abstract:
|
Online communities are important for external innovations. The success depends on attracting voluntary contributions of members. In this study, we investigate the effects of two motivating mechanisms, virtual rewards and reputation, on community contributions. By analyzing panel data from StackExchange.com, we find that these two mechanisms have positive effects on both the quantity and quality of user contributions. Our results provide important implications for theory and managerial practice.
