A shill, also called a plant or a stooge, is a person who publicly helps or gives credibility to a person or organization without disclosing that they have a close relationship with said person or organization, or have been paid to do so.

A shill may also act to discredit opponents or critics of the person or organization in which they have a vested interest.
An auction is usually a process of buying and selling goods or services by offering them up for bids, taking bids, and then selling the item to the highest bidder or buying the item from the lowest bidder. Some exceptions to this definition exist and are described in the section about different types. The branch of economic theory dealing with auction types and participants' behavior in auctions is called auction theory.
A Dutch auction is one of several similar types of auctions for buying or selling goods. Most commonly, it means an auction in which the auctioneer begins with a high asking price in the case of selling, and lowers it until some participant accepts the price, or it reaches a predetermined reserve price. This type of price auction is most commonly used for goods that are required to be sold quickly such as flowers, fresh produce, or tobacco. A Dutch auction has also been called a clock auction or open-outcry descending-price auction. This type of auction shows the advantage of speed since a sale never requires more than one bid. It is strategically similar to a first-price sealed-bid auction.
A Vickrey auction or sealed-bid second-price auction (SBSPA) is a type of sealed-bid 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. The auction was first described academically by Columbia University professor William Vickrey in 1961 though it had been used by stamp collectors since 1893. In 1797 Johann Wolfgang von Goethe sold a manuscript using a sealed-bid, second-price auction.
An English auction is an open-outcry ascending dynamic auction. It proceeds as follows.
A Japanese auction is a dynamic auction format. It proceeds in the following way.
A spectrum auction is a process whereby a government uses an auction system to sell the rights to transmit signals over specific bands of the electromagnetic spectrum and to assign scarce spectrum resources. Depending on the specific auction format used, a spectrum auction can last from a single day to several months from the opening bid to the final winning bid. With a well-designed auction, resources are allocated efficiently to the parties that value them the most, the government securing revenue in the process. Spectrum auctions are a step toward market-based spectrum management and privatization of public airwaves, and are a way for governments to allocate scarce resources.
A bidding fee auction, also called a penny auction, is a type of all-pay auction in which all participants must pay a non-refundable fee to place each small incremental bid. The auction is extended each time a new bid is placed, typically by 10 to 20 seconds. Once time expires without a new bid being placed, the last bidder wins the auction and pays the amount of that bid. The auctioneer profits from both the fees charged to place bids and the payment for the winning bid; these combined revenues frequently total more than the value of the item being sold. Empirical evidence suggests that revenues from these auctions exceeds theoretical predictions for rational agents. This has been credited to the sunk cost fallacy. Such auctions are typically held over the Internet, rather than in person.
Auction sniping is the practice, in a timed online auction, of placing a bid likely to exceed the current highest bid as late as possible—usually seconds before the end of the auction—giving other bidders no time to outbid the sniper. This can be done either manually or by software on the bidder's computer, or by an online sniping service.
Auction theory is an branch of applied economics that deals with how bidders act in auctions and researches how the features of auctions incentivise predictable outcomes. Auction theory is a tool used to inform the design of real-world auctions. Sellers use auction theory to raise higher revenues while allowing buyers to procure at a lower cost. The confluence of the price between the buyer and seller is an economic equilibrium. Auction theorists design rules for auctions to address issues that can lead to market failure. The design of these rulesets encourages optimal bidding strategies in a variety of informational settings. The 2020 Nobel Prize for Economics was awarded to Paul R. Milgrom and Robert B. Wilson "for improvements to auction theory and inventions of new auction formats."
A multiunit auction is an auction in which several homogeneous items are sold. The units can be sold each at the same price or at different prices.

The T206 Honus Wagner baseball card depicts the Pittsburgh Pirates' Honus Wagner, known as "The Flying Dutchman", a dead-ball era baseball player who is widely considered to be one of the best players of all time. The card was designed and issued by the American Tobacco Company (ATC) from 1909 to 1911 as part of its T206 series. Wagner refused to allow production of his baseball card to continue, either because he did not want children to buy cigarette packs to get his card, or because he wanted more compensation from the ATC. The ATC ended production of the Wagner card, and a total of only 50 to 200 cards were ever distributed to the public. In 1933, the card was first listed at a price value of US$50 in Jefferson Burdick's The American Card Catalog, making it the most expensive baseball card in the world at the time.
