Boundedly rational opinion dynamics in social networks : does indegree matter?
Battiston, Pietro; Stanca, Luca M. - 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...

Dissonance minimization and conversation in social networks
Anufriev, Mikhail; Borissov, Kirill; Pakhnin, Mikhail - 2021
We study a model of social learning in networks where the dynamics of beliefs are driven by conversations of dissonance-minimizing agents. Given their current beliefs, agents make statements, tune them to the statements of their associates, and then revise their beliefs. We characterize the...

The strength of weak leaders : an experiment on social influence and social learning in teams
Buechel, Berno; Klößner, Stefan; Lochmüller, Martin; … - 2018
We investigate how the selection process of a leader affects team performance with respect to social learning. We use a lab experiment in which an incentivized guessing task is repeated in a star network with the leader at the center. Leader selection is either based on competence, on...

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...

Formal covariate benchmarking to bound omitted variable bias
Basu, Deepankar - 2023
Covariate benchmarking is an important part of sensitivity analysis about omitted variable bias and can be used to bound the strength of the unobserved confounder using information and judgments about observed covariates. It is common to carry out formal covariate benchmarking after...

Covariate benchmarking for sensitivity analysis when the confounder is correlated with observed covariates
Basu, Deepankar - 2023
Covariate benchmarking is an important part of sensitivity analysis about omitted variable bias and can be used to bound the strength of the unobserved confounder using information and judgments about observed covariates. It is common to carry out formal covariate benchmarking under the...

Econometric issues in the analysis of contagion
Pesaran, M. Hashem; Pick, Andreas - 2004
that ignoring inter-dependence can introduce an upward bias in the estimate of the contagion coefficient, and using Monte …This paper presents a canonical, econometric model of contagion and investigates the conditions under which contagion … can be distinguished from inter-dependence. In a two-country (market) setup it is shown that for a range of fundamentals …
