Lock-in through passive connections

We consider a model of social coordination and network formation where agents decide on an action in game whom to establish costly links to. study the role passive connections; these are that other form given agent. Such connections may create endogenously arising lock-in don't switch actions links, as this result loss payoff received through them. When constrained number they form, set Nash equilibria includes action-heterogenous strategy profiles, different choose actions. Depending precise parameters model, risk-dominant, payoff-dominant, or profiles stochastically stable.
