Theories put forth to explain cooperation in public goods experiments usually assume either that subjects cooperate because they do not understand the game’s incentives or that cooperation stems from social motives such as altruism and reciprocity. Recent research by Andreoni (1995) is an important first attempt to distinguish the roles of confusion and social motives in these environments. How...

http://dx.doi.org/10.1016/j.anbehav.2014.09.004 0003-3472/© 2014 The Association for the Study of A Social networks arise from complex interactions among multiple individuals and affect the emergent properties of groups (e.g. cooperation, disease spread, information transfer, etc.).

Metanorms is a mechanism proposed to promote cooperation in social dilemmas. Recent experimental results show that network structures that underlie social interactions influence the emergence of norms that promote cooperation. We generalize Axelrod's analysis of metanorms dynamics to interactions unfolding on networks through simulation and mathematical modeling. Network topology strongly influ...
