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...

Econometric issues in the analysis of contagion

Pesaran, M. Hashem; Pick, Andreas - 2004

This paper presents a canonical, econometric model of contagion and investigates the conditions under which contagion … the solution is not unique, and for sufficiently large values of the contagion coefficients it has interesting bifurcation … contagion effects in the presence of inter-dependencies the equations for the individual markets or countries must contain …

Regression discontinuity designs based on population thresholds pitfalls and solutions

Eggers, Andrew C.; Freier, Ronny; Grembi, Veronica; … - 2015 - This version: September 2015

In many countries, important features of municipal government (such as the electoral system, mayors' salaries, and the number of councillors) depend on whether the municipality is above or below arbitrary population thresholds. Several papers have used a regression discontinuity design (RDD) to...

Understanding the SES gradient in health among the elderly : the role of childhood circumstances

Stowasser, Till; Heiss, Florian; McFadden, Daniel; … - 2014

Individuals' socioeconomic status (SES) is positively correlated with their health status. While the existence of this gradient may be uncontroversial, the same cannot be said about its explanation. In this paper, we extend the approach of testing for the absence of causal channels developed by...

"Healthy, wealthy, and wise?" revisited : an analysis of the causal pathways from socio-economic status to health

Stowasser, Till; Heiss, Florian; McFadden, Daniel; … - 2014

Much has been said about the stylized fact that the economically successful are not only wealthier but also healthier than the less affluent. There is little doubt about the existence of this socio-economic gradient in health, but there remains a vivid debate about its source. In this paper, we...
