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...

Smoking, like many health-related behaviors, has "social" aspects. The smoking habits of my neighbors are likely to shape my own smoking habits, due to what is known in economics as “peer effects”. These complementarities in behavior may result from emulation, joint consumption, conformism,...

We study linear quadratic games played on a network where strategies are complements between neighbors and substitutes between agents at distance-two. We provide micro-founded problems where this pattern of interaction is due to a local congestion effect. Equilibrium behavior systematically...
