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 on.
Auction sniping (also called bid sniping) is the practice, in a timed online auction, of placing a bid likely to exceed the current highest bid (which may be hidden) as late as possible—usually seconds before the end of the auction—giving other bidders no time to outbid the sniper.
This may in the future lead to a standardization of sourcing procedures, reduced order cycle, which can enable businesses to reduce prices and generally provide a higher level of service. [4] In a traditional auction, the seller offers an item for sale. Potential buyers are then free to bid on the item until the time period expires.
The automated trading system determines whether an order should be submitted based on, for example, the current market price of an option and theoretical buy and sell prices. [7] The theoretical buy and sell prices are derived from, among other things, the current market price of the security underlying the option.

[1] Potential buyers submit their bids and potential sellers submit their ask prices to the market institution, and then the market institution chooses some price p that clears the market: all the sellers who asked less than p sell and all buyers who bid more than p buy at this price p.

EBay rules give the winning bidder a three-day period to make payment. So in the likely event that Kluge's 15-year-old tormenter can't put up the money, the treasure hunter plans to put the recipe ...
Suppose that a buyer has value v and bids b. His opponent bids according to the equilibrium bidding strategy. The support of the opponent's bid distribution is [0,B(1)]. Thus any bid of at least B(1) wins with probability 1. Therefore, the best bid b lies in the interval [0,B(1)] and so we can write this bid as b = B(x) where x lies in [0,1].
