Convergence of cultural traits with time-varying self-confidence in the Panebianco (2014) model : a corrigendum
Panebianco, Fabrizio; Prummer, Anja; Siedlarek, Jan-Peter - 2017
We highlight that convergence in repeated averaging models commonly used to study cultural traits or opinion dynamics is not equivalent to convergence in Markov chain settings if transition matrices are time-varying. We then establish a new proof for the convergence of cultural traits in the...

A cross-country analysis of the risk factors for depression at the micro and macro level
Melgar, Natalia; Rossi, Máximo - 2010

Opinion dynamics and wisdom under conformity
Buechel, Berno; Hellmann, Tim; Kölßner, Stefan - 2014
We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors' expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an...

How homophily affects learning and diffusion in networks
Golub, Benjamin; Jackson, Matthew O. - 2009
We examine how three different communication processes operating through social networks are affected by homophily - the tendency of individuals to associate with others similar to themselves. Homophily has no effect if messages are broadcast or sent via shortest paths; only connection density...
