A first-price sealed-bid auction (FPSBA) is a common type of auction. It is also known as blind auction. [1] In this type of auction, all bidders simultaneously submit sealed bids so that no bidder knows the bid of any other participant. The highest bidder pays the price that was submitted. [2]: p2 [3]
That is, the payment of the winner in the sealed first-price auction is equal to the expected revenue in the sealed second-price auction. Proof of revenue equivalence. Suppose that buyer 2 bids according to the strategy () = /, where () is the buyer's bid for a valuation . We need to show that buyer 1's best response is to use the same strategy.
In an English auction, all current bids are visible to all bidders and in a sealed-bid auction, bidders only get to know if their bid was the best. Best/not best auctions are sealed-bid auctions with multiple bids, where the bidders submit their prices like in English auction and get responses about the leadership of their bid. [74]
A Vickrey–Clarke–Groves (VCG) auction is a type of sealed-bid auction of multiple items. Bidders submit bids that report their valuations for the items, without knowing the bids of the other bidders. The auction system assigns the items in a socially optimal manner: it charges each individual the harm they cause to other bidders. [1]
In sealed-bid first-price auctions, risk-averse bidders are more willing to bid more to increase their probability of winning, which, in turn, increases the bid's utility. This allows sealed-bid first-price auctions to produce higher expected revenue than English and sealed-bid second-price auctions.
In a sealed-bid second-price auction, there is a SBNE with =, i.e., each bidder bids exactly his/her signal. PROOF: The proof takes the point-of-view of Xenia. We assume that she knows that Yakov bids r Y {\displaystyle rY} , but she does not know Y {\displaystyle Y} .
In the sealed first-price auction, the increasing bid function B(v) is an equilibrium if bidding strategies are mutual best responses. That is, if buyer 1 has value v, their best response is to bid b = B(v) if they believes that their opponent is using this same bidding function. Suppose buyer 1 deviates and bids b = B(z) rather than B(v) . Let ...
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.
