Information quality in sequential persuasion

Author

Listed:
  • Kitano, Wataru

Abstract

In Bayesian persuasion with multiple senders disclosing information sequentially, the conditions under which the entry of new senders can reduce information quality remain ambiguous. This paper shows that informativeness-reducing entry can occur if and only if the incumbent sender exhibits a sufficiently strong aversion to full disclosure.
