This paper deals with the role of reciprocation in the formation of individuals’ social networks. We follow the activity of a panel of bloggers over more than a year and investigate the extent to which initiating a relation brings about its reciprocation. We adapt a standard capital investment...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

Trust and participation in social networks are inherently interrelated. We make use of India's demonetization policy, an unexpected and unforeseeable exogenous variation, to causally identify the effect of social networks in determining trust. We use first-hand quantitative and qualitative data...
