That's important because what it does is it encourages bidders to bid as high or as high as they can for inventory that they really want The generalized second-price auction (GSP) is a non-truthful auction mechanism for multiple items. Each bidder places a bid. The highest bidder gets the first slot, the second-highest, the second slot and so on, but the highest bidder pays the price bid by the second-highest bidder, the second-highest pays the price bid by the third-highest, and so. The second-price auction was first known as a Vickrey Auction. Bidders submit written bids without knowing the bid of the other people in the auction. The highest bidder wins but the price paid is the second-highest bid. This type of auction is strategically similar to an English auction and gives bidders an incentive to bid their true value

Second-price Sealed-bid Auction The second-price sealed-bid auction is similar to the first-price sealed-bid, except the highest bidder gets the item at the price of the second-highest bidder. For example, if the highest bidder won an auction with a bid of $500, and the previous high bid was $480, then the winning bidder only has to pay $480 for the item being sold second- and rst-price auctions. The auctioneer can take optimal bidding strategies and cal-culate the price that he will get if he conducts a rst or a second- price auction.
