Peer effects in public contributions: theory and experimental evidence Ballester, Coralio Brañas Garza, Pablo Espinosa, María Paz Public good game Social networks Conditional cooperation This paper analyzes the impact of social integration on cooperative behavior. We show that if the social network shows assortative mixing then conditional cooperation is an equilibrium strategy for altruistic subjects with a high degree of social integration.We provide experimental evidence on the relationship between individuals’ position in a social network and their contributions in a public good game. 2014-05-02T10:22:22Z 2014-05-02T10:22:22Z 2008 report Ballester, C.; Brañas-Garza, P.; Espinosa, M.P.
