Abstract

This paper brings together two major research streams in economic theory : information transmission in networks and strategic communication. The model embeds persuasion games of strategic disclosure by Milgrom (1981) into the communication network framework by Jackson and Wolinsky (1996). I find that the unique optimal network is a line in which players are ordered according to their bliss points. This ordered line is also pairwise-stable. This …nding stands in sharp contrast to previous results in network studies, that identify stars as the optimal and pairwise-stable networks when communication is non-strategic and subject to technological constraints. While stars are the most centralized minimally-connected networks, the line is the most decentralized one. These results may be especially relevant to political economy applications, such as networks of policymakers, interest groups, or judges
