The effect of preference similarity on the formation of clusters and the connectivity of social networks
作者：
Highlights：
• We analyze the formation of social networks determined by the preferences of their users.
• Users have incomplete information about the characteristics of friendship requesters.
• Similarity in the preferences exhibited by the users leads to more concentrated clusters.
• Disutility costs derived from a suboptimal acceptance decision increment cluster dispersion.
• Users with average preferences act as a connectivity-enhancing mechanism between clusters.
