We examine how three different communication processes operating through social networks are affected by homophily … on repeated averaging of neighbors' information and Markovian diffusion processes such as the Google random surfer model … friendship networks from the Adolescent Health dataset. …

The paper studies the impact of homophily on the optimal strategies of a monopolist, whose marketing campaign of new product relies on a word of mouth communication. Homophily is a tendency of people to interact more with those who are similar to them. In the model there are two types of...

This paper models the dynamic process through which a large society may succeed in building up its “social capital” by establishing a stable and dense pattern of interaction among its members. In the model, agents interact according to a collection of infinitely repeated Prisoner’s...

Our societies are heterogeneous in many dimensions such as census, education, religion, ethnic and cultural composition. The links between individuals - e.g. by friendship, marriage or collaboration - are not evenly distributed, but rather tend to be concentrated within the same group. This...

The explosion in online social networks motivates an enquiry into their structure and their welfare effects. A central … feature of these networks is information sharing: online social networks lower the cost of getting information from others …. These lower costs affect the attractiveness of individual search vis-a-vis a reliance on social networks. The paper reports …

This paper presents a model of collusive bargaining networks. Given a status quo network, game is played in two stages … to exist. In the networks with relatively few monopolized sellers, sharing leads to a complete reallocation of surplus to …

We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update …

We investigate the role of manipulation in a model of opinion formation. Agents repeatedly communicate with their neighbors in the social network, can exert effort to manipulate the trust of others, and update their opinions about some common issue by taking weighted averages of neighbors'...

Which types of networks favor the diffusion of innovations in the sense that an innovation whose intrinsic benefits are … game model of the diffusion of innovations. Here we study this question for a class of irregular random networks, Small … fraction of a large population? For deterministic and regular networks there are characterizations, based on a coordination …
