讲座题目:Targeted Interventions and Network Design

讲座摘要:We study the optimal intervention that maximizes total welfare, allowing for interventions in both intrinsic utilities of nodes, as well as the link intensities of  edges in the network. We characterize the planner’s choice of intervention, finding that the changes in link intensities between a pair of nodes are strongly related to the product of their eigen-centralities.  When the budget is large, the optimal network structure takes a very simple form: When the activities are strategic complements, a complete network is created; When the activities are strategic substitutes, a complete bipartite network with (almost) equal size is created.  We also consider the computation complexity of selecting the optimal bipartite network in the latter case.
