Experiments versus Distributions of Posteriors
Publication by Stefan Terstiege and Cédric Wasser in Mathematical Social Sciences.
"Highlights
- We consider a fundamental result in Bayesian persuasion and information design.
- A distribution of posteriors is induced by some experiment iff its mean is the prior.
- We present a general version that applies to infinite state and signal spaces.
Abstract
A fundamental result in Bayesian persuasion and information design states that a distribution of posterior beliefs can be induced by an experiment if and only if the posterior beliefs average to the prior belief. We present a general version of this result that applies to infinite state and signal spaces."
