INFORMATION DESIGN IN ALLOCATION WITH COSTLY VERIFICATION
ABSTRACT
A principal who values an object allocates it to one or more agents. Agents always want the object. Agents hold private signals about the allocation payoff to the principal and an information designer can influence agents’ signal distributions. Based upon the designed information, the principal designs a mechanism to maximizes her payoff monetary transfer is not available but the principal can verify any agent’s private signal at a cost. We find the agent-optimal information and the principal-optimal information. Moreover, with a single agent, any agent-optimal information is principal-worst. The latter facilitates the discovery of optimal robust mechanisms in general settings.
