Many social networks have the following properties: (i) a short average distance between any two individuals; (ii) a … high clustering coefficient; (iii) segregation patterns; the presence of (iv) brokers and (v) hubs. (i) and (ii) define a … parameters, all pairwise Nash (PN) networks have properties (i)-(iv). There are some PN networks with one hub. Cognizant agents …

impact of segregation and find that segregation leads to polarization. Segregation also reduces the overall number of people … informed in the long run. Our final set of results shows that agents are more likely to prefer segregation if their information …

A local public-good game played on directed networks is analyzed. The model is motivated by one-way flows of … wetlands. It is shown that in many (but not all) directed networks, there exists an equilibrium, sometimes socially desirable …

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

Only a very small number of networks are stable. Odd cycles and … networks consisting of dyads and at most one isolate are the only egalitarian, efficient, and stable networks for a large cost …

networks for which there is a convergence of beliefs. Finally, we survey some recent structural results on the speed of … convergence and relate these to issues of segregation, polarization and propaganda …
