Competitive Information Design with Asymmetric Senders
Zhicheng Du, Wei Tang, Zihe Wang, Shuo Zhang · 2024
We consider a competitive information design game in which there are multiple senders vie for the selection of a risk-neutral receiver by disclosing information about their individual state realizations. The receiver aims to select the sender who has the highest expected value of the state. We consider a general setting where the senders may be ex-ante heterogeneous, namely, while the senders' state realizations are independently distributed, they do not necessarily follow the same prior distributions. Each sender can only control the disclosure of information regarding his own state realizations, but there is no structural restriction on the set of the feasible information disclosing strategies.
