We consider the spread of a harmful state through a population divided into two groups. Interaction patterns capture the full spectrum of assortativity possibilities. We show that a central planner who aims for eradication optimally either divides equally the resources across groups, or...

We develop a model where workers, anticipating the possibility of unemployment, invest in connections to access information about available jobs. The investment in connections is high when the job separation rate is moderate, otherwise the investment in connections is low. The response of...

We introduce a tractable model of cheap talk among players located on networks. In our model, a player can send a message to another player if and only if he is linked to him. We derive a sharp equilibrium and welfare characterization which reveals two basic insights. In equilibrium, the...
