Title
Opinion Dynamics and Disagreements on Financial Networks
Authors
Abstract
We propose a new measure of disagreement based on connectedness, whichgeneralizes the disagreement index introduced in Billio et al. (2018). Building
on the lifting approach in Hendrickx (2014), we extend Billio et al. (2018) to
signed networks, which allows us to consider more general consensus dynamics and disagreement with antagonistic behaviour. Synthetic and real-world
financial networks of serial correlation are considered for illustrating the new
measure and for studying opinion dynamics and convergence to consensus on
prices for financial assets.
