Many types of economic and social activities involve significant behavioral complementarities (peer effects) with neighbors in the social network. The same activities often exert externalities that cumulate in "stocks" affecting agents' welfare and incentives. For instance, smoking is subject to...

We study properties of collective action problems bounded by minimal contributions as well as endowment and variable contributions are neighbourhood dependent. We relate nearness to non-interior agents and its implication for interior contribution. Here, we see the aspects of node distance to...

This paper presents a model of endogenous network formation in the presence of peer effects for a general class of payoff functions with local complementarities in effort levels and positive local externalities. Links are one-sided and agents move simultaneously. I find that equilibrium networks...
