many well-known results from the contest literature can be obtained by varying the structure of the network. Our framework …

This paper proposes new centrality measures to characterise the 'key class', when agents in a network are sorted into … role-equivalent classes, such that its removal results in an optimal change in the network activity. The notion of role … theoretical applicability. Players in the network engage in a non-cooperative game with local payoff complementarities. We …

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 …

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 …

This paper provides a game-theoretic model of network formation with a continuous effort choice. Efforts are strategic … complements for direct neighbors in the network and display global substitution/congestion effects. We show that if the parameter … links according to a network cost function. Again all socially optimal configurations are such that the network is a nested …

I present a behavioural model of network formation with positive network externalities in which individuals have …

We provide an overview and synthesis of the literatures analyzing games in which players are connected via a network … structure. We discuss, in particular, the impact of the structure of the network on individuals' behaviors. We focus on game …
