In this kind of auction, bidders submit simultaneous “sealed bids” to the seller. The terminology comes from the original format for such auctions, in which

some simple, informal observations that relate behavior in interactive auctions (ascending-bid and descending-bid auctions, which play out in real time) with behavior in sealed-bid auctions. These observations can be made mathematically rigorous, but for the discussion here we will stick to an informal description. Descending-Bid and First-Price Auctions

bidding one’s true value is a dominant strategy. Comparing Auction Formats. In the next two sections we will consider the two main formats for sealed-bid auctions in more detail. Before doing this, it’s worth making two points. First, the discussion in this section shows that when we analyze bidder behavior

in sealed-bid auctions, we’re also learning about their interactive analogues — with the descending-bid auction as the analogue of the sealed-bid first-price auction, and the

we mentioned toward the end of the previous section: with independent, private values, bidding your true value is a dominant strategy in a second price sealed-bid auction. That is, the best choice of bid is exactly what the object is worth to you. Formulating the Second-Price Auction as a Game. To

One that initially seems counter-intuitive in its formulation is the all-pay auction: each bidder submits a bid

why this should occur. You do not need to write a proof; an intuitive explanation is fine. 4. A seller will run a second-price, sealed-bid auction for an object. There are two bidders, a and b, who have independent, private values vi which are either 0 or 1. For both bidders

There is one seller who will sell one object using a second-price sealed-bid auction. The bidders have independent, private values drawn from a distribution on [0, 1]. If a bidder with value

price determination in a controlled setting. In our discussion of auctions, we found that if a seller with a single object runs a second-price sealed-bid auction — or equivalently an ascending-bid auction — then buyers bid their true values for the seller’s object. In that discussion, the buyers were choosing prices

single buyer interested in purchasing an object from one of several sellers. Here, our auction results imply that if the buyer runs a second-price sealed-bid auction (buying from the lowest bidder at the second-lowest price), or equivalently a descending-offer auction, then the sellers will offer to sell at their

no remaining items of any value. Thus, buyer 1 pays buyer 2’s valuation, and so we have precisely the pricing rule for second-price sealed-bid auctions. 15.4 Analyzing the VCG Procedure: Truth-Telling as a Dominant Strategy We now show that the VCG procedure encourages truth-telling in a matching
