In a Baron-Myerson setup, we study a situation where an agent is initi
ally uninformed, but can, at a cost, acquire information about the sta
te of nature before the principal offers him a contract. For intermedi
ate values of the cost of acquiring information, the agent's equilibri
um strategy will be a mixed strategy: He will acquire information with
a probability strictly between 0 and 1. We identify the contract that
the principal will offer to such a ''maybe informed'' agent. (C) 1998
