Eliciting prior beliefs

Abstract.
In this paper, we study elicitation of latent prior beliefs when the agent can acquire information via a costly attention strategy. We introduce a mechanism that simultaneously makes it strictly dominant to (a) not acquire any information, and (b) report truthfully. We call such a mechanism a robust proper scoring rule. We prove that such a scoring rule exists under two very mild regularity conditions. Our proof is constructive, thus identifying a specific family of robust proper scoring rules. Finally, we study the most interesting special case (viz., with entropic costs) and we identify a family of quadratic scoring rules that are robust.
