The same activities often exert externalities that cumulate in "stocks" affecting agents … network of social relations, as agents display strategic substitution with distance-two neighbors. We show that behavior is … behavior and key-players tend to move to the periphery of the network, and we discuss the effect of close-knit communities and …

The cost function of an agent … captures the cost that the agent incurs to maintain links in the network. With this utility function, we analyze what network … exists a pairwise stable network, which is also efficient. We show that all pairwise stable networks are efficient, and hence …

No study so far has attempted to investigate the role of … between his/her profile and the profile of the other player. At this point, a repeated network formation game ensues. We find …

High levels of clustering—the tendency for two nodes in a network to share a neighbor—are ubiquitous in economic and … otherwise separate network regions, representing rewards for filling “structural holes” in the sense of Burt (1992) and keeping … distances in networks short.

This paper analyses a simultaneous game of network formation and information acquisition where the benefit structure is … such that the benefit that an agent derives from the network she is located in depends on the maximum information that … someone in her neighbourhood, including herself, acquires.

This paper brings a general network analysis to a wide class of economic games. A network, or interaction matrix, tells … who directly interacts with whom. A major challenge is determining how network structure shapes overall outcomes. We have … a striking result.
