The economic consequences of social network structure
Jackson, Matthew O.; Rogers, Brian; Zenou, Yves - 2016
We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

Boundedly rational opinion dynamics in social networks: Does indegree matter?
Battiston, Pietro; Stanca, Luca - 2015
This paper investigates opinion dynamics and social influence in directed communication networks. We study the theoretical properties of a boundedly rational model of opinion formation in which individuals aggregate the information they receive from their neighbors by using weights that are a...

Naïve Learning in Social Networks: Convergence, Influence and Wisdom of Crowds
Jackson, Matthew O.; Golub, Benjamin - 2007
We study learning and influence in a setting where agents communicate according to an arbitrary social network and naïvely update their beliefs by repeatedly taking weighted averages of their neighbors' opinions. A focus is on conditions under which beliefs of all agents in large societies...
