The Relative Contributions of Private InformationSharing and Public Information Releases toInformation Aggregation
Duffie, Darrell; Malamud, Semyon; Manso, Gustavo - Swiss National Centre of Competence in Research North … - 2009
We calculate learning rates when agents are informed through both public andprivate observation of other agents’ actions. We provide an explicit solution forthe evolution of the distribution of posterior beliefs. When the private learningchannel is present, we show that convergence of the...
