The Social Collateral Approach to Social Capital

The social collateral approach to social capital provides a tractable framework to model cooperation in social networks. The approach was explored in a series of papers by Attila Ambrus, Dean Karlan, Markus Mobius, Tanya Rosenblat and Adam Szeidl. The main applications have been in modeling trust and risk-sharing.
