This problem can be allevi- Two auction theory professors, Lawrence M. Ausubel and Paul Milgrom, write about The Lovely but Lonely Vickrey Auction: “Despite the enthusiasm that the Vickrey mechanism and its extensions generate among economists, practical applications of Vickrey’s design are rare at best.” So why don’t more people use a second-bid auction?

The design of auctions is a very rich—and richly explored—topic. The Vickrey auction underlies eBay because when a bidder submits a bid in the eBay auction, the current “going” price is not the highest bid, but the second-highest bid plus a bid increment.
