The analysis of social reasoning is at the core of understanding how to manage social networks. Since interpersonal relations are composed of multiple factors with different nature (i.e., structural and social factors), the authors explore their influence on the strategizing processes in social networks. The research is based on the consideration of social networks in terms of network games. Therefore, they formalize interpersonal relations using the methods of structural and social analysis combined with game theoretic approach. Specifically, they formalize social power of an agent and use it to quantify payoffs.
