People regularly share items using online social media. However, people's decisions around sharing---who shares what to whom and why---are not well understood. We present a user study involving 87 pairs of Facebook users to understand how people make their sharing decisions. We find that even when sharing to a specific individual, people's own preference for an item (individuation) dominates over the recipient's preferences (altruism). People's open-ended responses about how they share, however, indicate that they do try to personalize shares based on the recipient. To explain these contrasting results, we propose a novel process model of sharing that takes into account people's preferences and the salience of an item. We also present encouraging results for a sharing prediction model that incorporates both the senders' and the recipients' preferences. These results suggest improvements to both algorithms that support sharing in social media and to information diffusion models.
This research examined the relation between self-relevance and word-of-mouth (WOM). The results of two studies suggest consumers are more likely to provide WOM for products that are relevant to self-concept than for more utilitarian products. There was also some indication that WOM was biased, in the sense that consumers exaggerated the benefits of self-relevant products compared to utilitarian products. Finally, self-relevance had a greater impact on WOM in individualist cultures than collectivist cultures, consistent with differences in the way self-concept is typically construed by these groups. Implications for marketing strategies concerning WOM are discussed. We review several studies examining perspective-taking in communication. One set of studies indicates that speakers exploit the common ground they share with their addressees in creating referring expressions and that such perspective-taking improves the listener's comprehension. A second set of studies examines an element of the perspective-taking process itself: the accuracy of people's assessments of others' knowledge. We find that such estimates are both fairly accurate and biased in the direction of the perceiver's own knowledge. However, the extent of their influence on message formulation depends on the availability of feedback. We conclude that perspective-taking in communication combines prior theories about what others know with information drawn from such conversational resources as verbal and nonverbal feedback. ABSTRACTMarketers have long understood that consumers’ self-concepts influence the products they purchase; conversely, products purchased influence people’s self-concepts. Might the same self-enhancement framework apply in to shared online advertisements? Using the symbolic interactionist perspective of identity theory, this study empirically tests the proposition that online consumers use electronic word of mouth, and specifically the sharing of online advertising, to construct and express their self-concepts. The results suggest that self-brand congruity, entertainment value, and product category involvement increase the self-expressiveness of online ads, which then increase the likelihood of sharing those ads. These findings have both theoretical and managerial implications.
