We consider the spread of a harmful state through a population that is divided into two groups. The groups interact with each other to an extent that is parameterized, capturing the full spectrum from perfectly positive to perfectly negative assortativity. We first consider a central planner who...

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...
