I present a behavioural model of network formation with positive network externalities in which individuals have preferences for being part of a clique. The behavioural model leads to an associated supermodular (Topkis, 1979) normal form game. I show that the behavioural model converges to the...

I look at the equilibrium effects of homophily in network formation games having positive externalities. I show that very weak preferences for network effects (such as preference for being part of a clique) may result in very high levels of homophily at equilibrium. I present an empirical...

Community mobilization is a key feature of community-based development projects. Community mobilization requires facilitating communication between village members and between leaders and the rest of the community. Is communication an effective device through which mobilization may foster...

Why do farm households inefficiently allocate resources across the plots they cultivate? We explore how these production inefficiencies relate to consumption decisions and information sharing within the household. In a lab-in-the-field experiment, male producers allocate too few inputs to their...
