Key players in network-oriented interventions

Individuals who are embedded in a social network decide non-cooperatively how much effort to exert in supporting victims of misbehavior. Each individual’s optimal effort depends on the contextual effect, the social multiplier effect and the social conformity effect. We characterize the Nash equilibr...

We characterize the Nash equilibrium and we derive an inter-centrality measure for finding the key player who once isolated increases the most the aggregate effort. An individual is more likely to be the key player if she is influencing many other individuals, she is exerting a low effort because of her characteristics, and her neighbors are strongly influenced by her. The key player policy increases substantially the aggregate effort and the targeted player should never be selected randomly.
