The Insider'S Curse

This paper studies an auction model in which one of the bidders, the insider, has better information about a common component of the value of the good for sale, than the other bidders, the outsiders. Our main result shows that the insider may have incentives to disclose her private information if she faces sufficiently strong competition from the outsiders. We also show that the insider can protect the value of her private information by hiding her presence in the auction to the outsiders. Finally, we analyze the implications of information revelation on the efficiency of the auction and on the auctioneer's expected revenue.
