Social Anti-Percolation and Negative Word of Mouth
Many new products fail, despite preliminary market surveys having determined considerable potential market share. This effect is too systematic to be attributed to bad luck. We suggest an explanation by presenting a new percolation theory model for product propagation, where agents interact over a social network. In our model, agents who do not adopt the product spread negative word of mouth to...
متن کاملSocial Anti-Percolation, Resistance and Negative Word-of-Mouth
A known result from marketing research is that many products fail to meet their expected market share. A possible explanation for this phenomenon is the inherent resistance of the social network, that is greatly increased if effects of negative word of mouth (NWOM) are taken into account. Here we suggest an extension for the Social Percolation framework that incorporates NWOM. The proposed mode...
متن کاملJob Matching , Social Network and Word - of - Mouth Communication ∗
Workers are embedded within a network of social relationships and can communicate through word-of-mouth. They can Þnd a job through either formal agencies or personal contacts. From this micro scenario, we derive an aggregate matching function that has the standard properties but fails to be homogeneous of degree one. Search frictions arise endogenously because of coordination failures between ...

متن کاملWord of Mouth: Rumor Dissemination in Social Networks
In this paper we examine the diffusion of competing rumors in social networks. Two players select a disjoint subset of nodes as initiators of the rumor propagation, seeking to maximize the number of persuaded nodes. We use concepts of game theory and location theory and model the selection of starting nodes for the rumors as a strategic game. We show that computing the optimal strategy for both...
