Protecting the winner. Second-price versus oral auctions

Richard Engelbrecht-Wiggans, Charles M. Kahn

Research output: Contribution to journalArticlepeer-review


In oral auctions, unlike sealed-bid second-price auctions, the winner never reveals his reservation price. We investigate bidders' strategies in the two auctions when third-parties can exploit information revealed by the auction. When exploitation is likely, oral auctions are more efficient than sealed-bid second-price auctions, and preferred by all participants.
