Abstract
This paper studies the dynamics of information diffusion within networks, encompassing both general and targeted dissemination. We first characterize the theoretical foundations of diffusion centrality. Next, we introduce two extensions of diffusion centrality: targeting centrality and reachability, that we believe to better capture situations involving targeted requests. We derive general explicit formulas for the computation of these novel centrality measures.
期刊介绍:
The Journal of Economic Theory publishes original research on economic theory and emphasizes the theoretical analysis of economic models, including the study of related mathematical techniques. JET is the leading journal in economic theory. It is also one of nine core journals in all of economics. Among these journals, the Journal of Economic Theory ranks fourth in impact-adjusted citations.
