An auction is a process of buying and selling goods by offering them up for bid, taking bids, and then selling the item to the winning bidder. In economic theory, an auction may refer to any mechanism or set of trading rules for exchange. There are several variations on the basic auction form, including time limits, minimum or maximum limits on bid prices, and special rules for determining the winning bidder(s) and sale price(s). Participants in an auction may or may not know the identities or actions of other participants. Depending on the auction, bidders may participate in person or remotely through a variety of means, including telephone and the internet. Auctions are generally funded by a fee paid by the seller to the auctioneer or auction company.
History of the Auction
Auctioning can be traced as far back as 500 B.C.[1] According to ancient Greek scribes, the more generally accepted auction occurred first in Babylon in 500 B.C. During this period, auctions were held annually, and women were sold on the condition of marriage. It was considered illegal to allow a daughter to be sold outside the auction method. Women with “beauty” engendered higher bidding, women without “beauty” had to pay a dowry to be accepted into the auction, and thus the price would be negative. During the Roman Empire, following military victory, Roman soldiers would often spear the ground to mark the location of spoils in which goods and property were seized. Roman business agents were said to have accompanied warriors into battle to help facilitate expected sales. The Romans also used the auction to liquidate their own property. For example, Marcus Aurelius is said to have auctioned prized heirlooms and furniture, (an auction that, as legend has it, lasted over two months). The most legendary auction occurred in the year 193 A.D. when the entire Roman Empire was put on the auction block by the Praetorian Guard. On March 23rd, The Praetorian Guard first killed Pertinax the emperor, and then announced that the highest bidder could claim the entire Empire. Didius Julianus outbid everyone else for the price of 6,250 drachmas per Guard, an act that initiated a brief civil war. Didius was then beheaded two months later when Septimus Severus conquered Rome. During the end of the 18th century, soon after the French Revolution, auctions came to be held in taverns and coffeehouses to sell art. Such auctions were held daily, and catalogs were printed to announce available items. Such Auction catalogs are frequently printed and distributed before auctions of rare or collectible items. Many of these catalogs may be very elaborate works themselves, with considerable details about the items being auctioned. During the American civil war, goods seized by armies were sold at auction by the Colonel of the division. Thus, some of today's auctioneers in the U.S. carry the unofficial title of "colonel". Auctioneers are usually trained in the legal and practical aspects of conducting auctions. Some jurisdictions require auctioneers to be licensed and bonded. Major auction houses include Christie's, Sotheby's, Lyon & Turnbull, and Bonhams. The Stockholms Auktionsverk, the world's oldest auction house, was established in 1674 in Sweden. Internet auctions, such as eBay and GoIndustry, have become very popular with the prevalence of Internet. Other websites, such as AuctionZip and Auctioneers, display live auction listings from auctioneers nationwide. Auctions held by members of the United States Executive Branch are commonly held which feature property that was seized that was, to what they believed, used in the event of a crime. The issue of the morality of this process is debated and is what some would compare to the act of stealing. Types of auction
JEL ClassificationIn the Journal of Economic Literature "Classification System" D stands for "Microeconomics" with division D4 for "Market Structure and Pricing" and subdivisions D44 for "Auctions" and D46 for "Value Theory". (C7 for "Game Theory" and C78 for "Bargaining Theory"). Auctions: CharacterizationAuctions can differ in the number of participants:
Prices are bid (or offered) by buyers and asked by sellers. Auctions may also differ by the procedure for bidding (or asking, as the case may be):
Auctions may differ as to the price at which the item is sold, whether the first (best) price, the second price, the first unique price or some other. Auctions may set a reservation price which is the least/maximum acceptable price for which a good may be sold/bought. Without modification, auction generally refers to an open, demand auction, with or without a reservation price (or reserve), with the item sold to the highest bidder. Image:Supplyauction.JPG

Primary types of auction
In some cases, bids may be made absentee, by leaving them with the auctioneer, or by phone or by Internet (in which case live bids may also be visible online). A variant popular in the time of Samuel Pepys was 'auction by candle' in which the winning (highest) bid was the last one to be made before a small piece of lit candle died out.[2] Such auctions can be vulnerable to collusion: Two or more bidders act together to win the auction. Following the auction result, the "loser" threatens to sue the winner, who then proposes a settlement. The settlement is actually the pre-agreed reward for the loser's cooperation. This strategy was described by the economist Susan Athey.
All of the private value auctions listed above are revenue equivalent assuming complete information, meaning that they all result in the same expected revenue for a seller. Time requirementsEach type of auction has its specific qualities such as pricing accuracy and time required for preparing and conducting the auction. The number of simultaneous bidders is of critical importance. Open bidding during an extended period of time with many bidders will result in a final bid, that is very close to the true market value. Where there are few bidders and each bidder is allowed only one bid, time is saved, but the winning bid may not reflect the true market value with any degree of accuracy. Of special interest and importance during the actual auction is the time elapsed from the moment that the first bid is revealed to the moment that the final (winning) bid has become a binding agreement. Dutch auction or (a low) Posted price are pricing methods, used when speed is important. Swedish auction or French auction are used when accurate pricing is important. Asking price, English auction or First price auction are used in most other cases. The diagram shows typical time requirements:

Seconds Minutes Days Months
English auction (since 1674) is used for chattel (20 seconds), art, antiques (90 seconds) and (especially in Australia) for real estate (10 minutes). A valuation and/or a SOB Suggested Opening Bid is announced. At least two bidders are required. Candle auction (since 1490) preceded English auction. (15 to 20 minutes). Dutch auction (since 1887) is used for wholesale cut flowers, tobacco, farm products, fish and other perishables. (4 seconds). First price auction (or sealed bids) (since 1770) is used for industrial real estate, building contract work and whenever only one or very few bidders are expected to participate. (1 second). Swiss auction (since 1950) is used for building contract work, where the winning bid is subject to certain conditions. The bid is thus not immediately binding for the winning bidder. (5 days). Second price auction (or Vickrey auction) (since 1961) is used for treasury bills. (1 second). French auction (or Tâtonnement or Walrasian auction) (since 1874) is used for gold, stocks and bonds. (4 to 20 seconds). Swedish auction (or Swedeauction) (since 1982) is used for various types of family homes. (10 days). (The General Services Administration GSA uses on-line auctions that are practically the same as Swedish auction. GSA is the United States government agency for the sale of surplus real estate). Simplified Swedish auction (since 2002) is used for most family homes in Sweden´s metropolitan areas. (4 days). Asking price is not an auction. This pricing method emerged about 1200 B.C. for chattel in Iraq. It is still used for chattel, second-hand cars and real estate, especially outside the metropolitan areas. (Lasting one year in a business recession). In a rising market, what starts as an Asking Price, may eventually become an English Auction, if surprisingly many bidders show up. Posted price is not an auction. This pricing method emerged about 2000 B.C. for real estate in Israel and was reintroduced in 1850 at new department stores in France. It is mostly used for massproduced products such as food, new retail articles and newly-built real estate. (1 second). Since 1980 a barcode often instantly sets the price at the check-out counter. SOB, Suggested Opening BidThere will always be some kind of (rough) estimate as to what the object will fetch. In an ascending open auction it is considered important that there should be at least a 50 percent increase in the bids from start to finish. To accomplish this the auctioneer must start the auction by announcing a Suggested Opening Bid, SOB, that is low enough to be immediately accepted by one of the bidders. Once there is an Opening Bid there will quickly be several other higher bids submitted. Experienced auctioneers will often select an SOB that is about 45 percent of the (lowest) estimate. Thus there is a certain margin of safety to ensure that there will indeed be a lively auction with many bids submitted. Several observations indicate, that the lower the SOB, the higher the final winning bid will be. This is due to the increase in number of bidders attracted by the low SOB. When 50 bidders compete with each other the winning bid will be about twice as high as when only two bidders compete. Often with Swedish auction and sometimes with English auction there will be more than 50 bidders. Other auction terminology
In terms of security/privacy, there are two main types of auctions:
In terms of auctioneers and auction items, we can differentiate three types of auctions:
If more than one identical item is sold, there are two possible generalizations of the second-price auction. In a uniform-price auction, all of the winning bidders pay the price submitted by the highest non-winning bidder. Bidders will not typically bid their true value in a uniform-price auction with multiple units. In a Vickrey (or second-price sealed-bid) auction, the pricing rule is more complicated, but preserves the property that bidders will bid their true valuation. It is also possible to auction each identical item individually. Once each item has been priced, the winning bidder is entitled to buy the remaining goods at the same price. Items the winning bidder opts not to purchase are auctioned again. This system creates a tension between the desire to hold back on bidding since later items will almost certainly be cheaper, and the chance that by losing the first round of bidding all possibility of purchasing will be lost. Work in the theory of auctions contributed to Vickrey's 1996 Bank of Sweden Prize. ("Nobel Prize").
Common uses for auctionsAuctions are publicly and privately seen in several contexts and almost anything can be sold at auction. Some typical auction arenas include the following:
Although less publicly visible, the most economically important auctions are the commodities auctions in which the bidders are businesses even up to corporation level. Examples of this type of auction include:
