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 …

We consider network games in which players simultaneously form partnerships and choose actions. Players are …. We find that, despite the symmetry and simplicity of the setting, quite irregular network structures can arise in …

networks form, the impact of network structure on agents' outcomes, and the evolution of networks over time. For this purpose …, we combine a network game introduced by Ballester et al. [2006], where the Nash equilibrium action of each agent is … proportional to her Bonacich centrality, with an endogenous network formation process. Links are formed on the basis of agents …

, I provide a proposition that generalizes the results of these two models by stating that: (i) Strict Nash network … network as in Billand et al (2011). This proposition requires that a certain restriction on link formation cost (called …
