TITLE: Interacting Bayesian Agents on Networks

ABSTRACT:
Consider a network of experts who try to predict if a certain movie
will win an Oscar. When small groups of experts meet at various
workshops and seminars they each state who is the more likely
candidate to win in their view and then use Bayes rule to update their
own private probability regarding the winner given what they've heard.
This type of model has been studied extensively in theoretical
economics. The main results proven in the economics literature concern
the question of the convergence of opinions: do all experts end up
agreeing on who is the more likely candidate to win? I will review
some of the results from the economics literature and discuss a number
of new results with Sly and Tamuz answering the questions of the
aggregation power of this process: does this distributed process
aggregate the information as well a centralized process?
