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...

Opinion dynamics and wisdom under conformity
Buechel, Berno; Hellmann, Tim; Klößner, Stefan - 2013
We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model may state...

This paper studies the phenomenon of early hiring in entry-level labor markets (e.g. the market for gastroenterology fellowships and the market for judicial clerks) in the presence of social networks. We offer a two-stage model in which workers in training institutions reveal information on...

Market Structure and Matching with Contracts
Westkamp, Alexander - 2010
Ostrovsky [10] develops a theory of stability for a model of matching in exogenously given networks. For this model a … generalization of pairwise stability, chain stability, can always be satisfied as long as agents’ preferences satisfy same side … contract with each other are jointly necessary and sufficient for (i) the equivalence of group and chain stability, (ii) the …

Populism and polarization in social media without fake news : the vicious circle of biases, beliefs and network homophily?
Hakobyan, Zaruhi; Koulovatianos, Christos - 2020
We build a model of network dynamics with decision-making under incomplete information in order to understand the determinants of the observed gradual downgrading of expert opinion on complicated issues and the decreasing trust in science. We suggest a search and matching mechanism behind...
