Auction
An auction is a process of buying and selling goods or services by offering them up for bid, taking bids, and then selling the item to the highest bidder. In economic theory, an auction may refer to any mechanism or set of trading rules for exchange.
History of the auction
The word "auction" is derived from the Latin augeō which means "I increase" or "I augment".[4]
For most of history, auctions have been a relatively uncommon way to negotiate the exchange of goods and commodities. In practice, both haggling and sale by set-price have been significantly more common.[5] Indeed, prior to the seventeenth century the few auctions that were held were sporadic and infrequent.[6]
Nonetheless, auctions have a long history, having been recorded as early as 500 B.C.[7] According to Herodotus, in Babylon auctions of women for marriage were held annually. The auctions began with the woman the auctioneer considered to be the most beautiful and progressed to the least. It was considered illegal to allow a daughter to be sold outside of the auction method.[6]
During the Roman Empire, following military victory, Roman soldiers would often drive a spear into the ground around which the spoils of war were left, to be auctioned off. Later slaves, often captured as the "spoils of war", were auctioned in the forum under the sign of the spear, with the proceeds of sale going towards the war effort.[6]
The Romans also used auctions to liquidate the assets of debtors whose property had been confiscated.[8] For example, Marcus Aurelius sold household furniture to pay off debts, the sales lasting for months.[9] One of the most significant historical auctions occurred in the year 193 A.D. when the entire Roman Empire was put on the auction block by the Praetorian Guard. On March 23 The Praetorian Guard first killed emperor Pertinax, then offered the empire to the highest bidder. 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 Septimius Severus conquered Rome.[8]
From the end of the Roman Empire to the eighteenth century auctions lost favor in Europe,[8] while they had never been widespread in Asia.[6]
In some parts of England during the seventeenth and eighteenth centuries auction by candle was used for the sale of goods and leaseholds. This auction began by lighting a candle after which bids were offered in ascending order until the candle spluttered out. The high bid at the time the candle extinguished itself won the auction.[10]
The oldest auction house in the world is Stockholm Auction House (Stockholms Auktionsverk). It was established in Sweden in 1674.[11][12]
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. In some cases these catalogs were elaborate works of art themselves, containing considerable detail about the items being auctioned.
Sotheby's, now the world's second-largest auction house,[11] held its first auction in 1744. Christie's, now the world's largest auction house,[11] was established around 1766. Other early auction houses that are still in operation include Dorotheum (1707),Mallams (1788), Bonhams (1793), Phillips de Pury & Company (1796), Freeman's (1805) and Lyon & Turnbull (1826).[13]
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". [9]
The development of the internet, however, has led to a significant rise in the use of auctions as auctioneers can solicit bids via the internet from a wide range of buyers in a much wider range of commodities than was previously practical.[5]
In 2008, the National Auctioneers Association reported that the gross revenue of the auction industry for that year was approximately $268.4 billion, with the fastest growing sectors being agricultural, machinery, and equipment auctions and residential real estate auctions.
Types of auction
Primary types of auction
- English auction, also known as an open ascending price auction. This type of auction is arguably the most common form of auction in use today.[4] Participants bid openly against one another, with each subsequent bid higher than the previous bid.[14] An auctioneer may announce prices, bidders may call out their bids themselves (or have a proxy call out a bid on their behalf), or bids may be submitted electronically with the highest current bid publicly displayed.[14] In some cases a maximum bid might be left with the auctioneer, who may bid on behalf of the bidder according to the bidder's instructions.[14] The auction ends when no participant is willing to bid further, at which point the highest bidder pays their bid.[14] Alternatively, if the seller has set a minimum sale price in advance (the 'reserve' price) and the final bid does not reach that price the item remains unsold.[14] Sometimes the auctioneer sets a minimum amount by which the next bid must exceed the current highest bid.[14] The most significant distinguishing factor of this auction type is that the current highest bid is always available to potential bidders.[14] The English auction is commonly used for selling goods, most prominently antiques and artwork,[14] but also secondhand goods and real estate. At least two bidders are required.
- Dutch auction also known as an open descending price auction.[4] In the traditional Dutch auction the auctioneer begins with a high asking price which is lowered until some participant is willing to accept the auctioneer's price.[14] The winning participant pays the last announced price.[4] The Dutch auction is named for its best known example, the Dutch tulip auctions. ("Dutch auction" is also sometimes used to describe online auctions where several identical goods are sold simultaneously to an equal number of high bidders.[15]) In addition to cut flower sales in the Netherlands, Dutch auctions have also been used for perishable commodities such as fish and tobacco.[14] In practice, however, the Dutch auction is not widely used.[4]
- Sealed first-price auction, also known as a first-price sealed-bid auction (FPSB). 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 they submitted.[4][14] This type of auction is distinct from the English auction, in that bidders can only submit one bid each. Furthermore, as bidders cannot see the bids of other participants they cannot adjust their own bids accordingly.[14] This kind of bid produces the same outcome as Dutch auction.[16] Sealed first-price auctions are commonly used in tendering, particularly for government contracts and auctions for mining leases.[14]
- Vickrey auction, also known as a sealed-bid second-price auction.[17] This is identical to the sealed first-price auction except that the winning bidder pays the second highest bid rather than his or her own.[18] This is very similar to the proxy bidding system used by eBay, where the winner pays the second highest bid plus a bidding increment (e.g., 10%).[17] Although extremely important in auction theory, in practice Vickrey auctions are rarely used.[14]
Multi-unit auctions sell more than one identical item at the same time, rather than having separate auctions for each. This type can be further classified as a uniform price auction or a discriminatory price auction.
Secondary types of auction
- All-pay auction is an auction in which all bidders must pay their bids regardless of whether they win. The highest bidder wins the item. All-pay auctions are primarily of academic interest, and may be used to model lobbying/bribery (bids are political contributions) or competitions such as a running race.[19]
- Bidding fee auction, also known as a penny or lowest unique bid auction, requires that each participant must purchase bids prior to placing them. When an auction's time expires, the last bidder wins the item and must pay a final bid price.[20] An example of this type of auction is Madbid or Sweepola.
- Buyout auction is an auction with a set price (the 'buyout' price) that any bidder can accept at any time during the auction, thereby immediately ending the auction and winning the item.[21] If no bidder chooses to utilize the buyout option before the end of bidding the highest bidder wins and pays their bid.[21] Buyout options can be either temporary or permanent.[21] In a temporary-buyout auction the option to buy out the auction is not available after the first bid is placed.[21] In a permanent-buyout auction the buyout option remains available throughout the entire auction until the close of bidding.[21] The buyout price can either remain the same throughout the entire auction, or vary throughout according to rules or simply at the whim of the seller.[21]
- Combinatorial auction is any auction for the simultaneous sale of more than one item where bidders can place bids on an "all-or-nothing" basis on "packages" rather than just individual items. That is, a bidder can specify that he or she will pay for items A and B, but only if he or she gets both.[22] In combinatorial auctions, determining the winning bidder(s) can be a complex process where even the bidder with the highest individual bid is not guaranteed to win.[22] For example, in an auction with four items (W, X, Y and Z), if Bidder A offers $50 for items W & Y, Bidder B offers $30 for items W & X, Bidder C offers $5 for items X & Z and Bidder D offers $30 for items Y & Z, the winners will be Bidders B & D while Bidder A misses out because the combined bids of Bidders B & D is higher ($60) than for Bidders A and C ($55).
- Generalized second-price auction
- Japanese auction is a variation of the English auction. When the bidding starts no new bidders can join, and each bidder must continue to bid each round or drop out. It has similarities to the ante in Poker.[23]
- Lloyd's syndicate auction.[24]
- No-reserve auction (NR), also known as an absolute auction, is an auction in which the item for sale will be sold regardless of price.[25][26] From the seller's perspective, advertising an auction as having no reserve price can be desirable because it potentially attracts a greater number of bidders due to the possibility of a bargain.[25] If more bidders attend the auction, a higher price might ultimately be achieved because of heightened competition from bidders.[26] This contrasts with a reserve auction, where the item for sale may not be sold if the final bid is not high enough to satisfy the seller. In practice, an auction advertised as "absolute" or "no-reserve" may nonetheless still not sell to the highest bidder on the day, for example, if the seller withdraws the item from the auction or extends the auction period indefinitely,[27] although these practices may be restricted by law in some jurisdictions or under the terms of sale available from the auctioneer.
- Reserve auction is an auction where the item for sale may not be sold if the final bid is not high enough to satisfy the seller; that is, the seller reserves the right to accept or reject the highest bid.[26] In these cases a set 'reserve' price known to the auctioneer, but not necessarily to the bidders, may have been set, below which the item may not be sold.[25] The reserve price may be fixed or discretionary. In the latter case, the decision to accept a bid is deferred to the auctioneer, who may accept a bid that is marginally below it. A reserve auction is safer for the seller than a no-reserve auction as they are not required to accept a low bid, but this could result in a lower final price if less interest is generated in the sale.[26]
- Reverse auction is a type of auction in which the roles of the buyer and the seller are reversed, with the primary objective to drive purchase prices downward.[28] While ordinary auctions provide suppliers the opportunity to find the best price among interested buyers, reverse auctions give buyers a chance to find the lowest-price supplier. During a reverse auction, suppliers may submit multiple offers, usually as a response to competing suppliers’ offers, bidding down the price of a good or service to the lowest price they are willing to receive. By revealing the competing bids in real time to every participating supplier, reverse auctions promote “information transparency”. This, coupled with the dynamic bidding process, improves the chances of reaching the fair market value of the item.[29]
- Silent auction is a variant of the English auction in which bids are written on a sheet of paper. At the predetermined end of the auction, the highest listed bidder wins the item.[30] This auction is often used in charity events, with many items auctioned simultaneously and "closed" at a common finish time.[30] The auction is "silent" in that there is no auctioneer selling individual items,[30] the bidders writing their bids on a bidding sheet often left on a table near the item.[31] At charity auctions, bid sheets usually have a fixed starting amount, predetermined bid increments, and a "guaranteed bid" amount which works the same as a "buy now" amount. Other variations of this type of auction may include sealed bids.[30] The highest bidder pays the price he or she submitted.[30]
- Senior auction is a variation on the all-pay auction, and has a defined loser in addition to the winner. The top two bidders must pay their full final bid amounts, and only the highest wins the auction. The intent is to make the high bidders bid above their upper limits. In the final rounds of bidding, when the current losing party has hit their maximum bid, they are encouraged to bid over their maximum (seen as a small loss) to avoid losing their maximum bid with no return (a very large loss).[32]
- Top-Up auction is a variation on the all-pay auction, primarily used for charity events. Bidders must pay the difference between their bid and the next lowest bid, whether they win or not. Only the winning bidder does not have to pay the "top-up" fee, but does have to pay for the item.
- Walrasian auction or Walrasian tâtonnement is an auction in which the auctioneer takes bids from both buyers and sellers in a market of multiple goods.[33] The auctioneer progressively either raises or drops the current proposed price depending on the bids of both buyers and sellers, the auction concluding when supply and demand exactly balance.[34] As a high price tends to dampen demand while a low price tends to increase demand, in theory there is a particular price somewhere in the middle where supply and demand will match.[33]
- Auction by the candle. A type of auction, used in England for selling ships, in which the highest bid laid on the table when a guttering candle expires wins.
- Other auctions: Other auction types also exist such as Simultaneous Ascending Auction,[35] Anglo-Dutch auction,[36] Private value auction,[37] Common value auction
Time requirements
Each 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.
Auctions: characterization
Auctions can differ in the number of participants:
- In a supply (or reverse) auction, m sellers offer a good that a buyer requests
- In a demand auction, n buyers bid for a good being sold
- In a double auction n buyers bid to buy goods from m sellers
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):
- In an open auction participants may repeatedly bid and are aware of each other's previous bids.
- In a closed auction buyers and/or sellers submit sealed bids
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.
Common uses for auctions
Auctions are publicly and privately seen in several contexts and almost anything can be sold at auction. Some typical auction arenas include the following:
- The antique business, where besides being an opportunity for trade they also serve as social occasions and entertainment
- In the sale of collectibles such as stamps, coins, classic cars, fine art[38] and luxury real estate
- The wine auction business, where serious collectors can gain access to rare bottles and mature vintages, not typically available through retail channels
- In the sale of all types of real property including residential and commercial real estate, farms, vacant lots and land.
- For the sale of consumer second-hand goods of all kinds, particularly farm (equipment) and house clearances and online auctions.
- Sale of industrial machinery, both surplus or through insolvency.
- In commodities auctions, like the fish wholesale auctions
- In livestock auctions where sheep, cattle, pigs and other livestock are sold. Sometimes very large numbers of stock are auctioned, such as the regular sales of 50,000 or more sheep during a day in New South Wales.[39]
- In wool auctions where international agents purchase lots of wool[40]
- Thoroughbred horses, where yearling horses and other bloodstock are auctioned.[41]
- In legal contexts where forced auctions occur, as when one's farm or house is sold at auction on the courthouse steps.
- Travel tickets. One example is SJ AB in Sweden auctioning surplus at Tradera (Swedish eBay).
- Holidays. A variety of holidays are available for sale online particularly via eBay. Vacation rentals appear to be most common. Many holiday auction websites have launched but failed.[42]
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:
- Sales of businesses
- Spectrum auctions, in which companies purchase licenses to use portions of the electromagnetic spectrum for communications (e.g., mobile phone networks)
- Private electronic markets using combinatorial auction techniques to continuously sell commodities (coal, iron ore, grain, water...) to a pre-qualified group of buyers (based on price and non-price factors)
- Timber auctions, in which companies purchase licenses to log on government land
- Timber allocation auctions, in which companies purchase timber directly from the government Forest Auctions
- Electricity auctions, in which large-scale generators and consumers of electricity bid on generating contracts
- Environmental auctions, in which companies bid for licenses to avoid being required to decrease their environmental impact. These include auctions in emissions trading schemes.
- Debt auctions, in which governments sell debt instruments, such as bonds, to investors. The auction is usually sealed and the uniform price paid by the investors is typically the best non-winning bid. In most cases, investors can also place so called non-competitive bids, which indicates an interest to purchase the debt instrument at the resulting price, whatever it may be
- Auto auctions, in which car dealers purchase used vehicles to retail to the public.[43]
Bidding strategy
Bid shading
Bid shading is placing a bid which is below the bidder's actual value for the item. Such a strategy risks losing the auction, but has the possibility of winning at a low price. Bid shading can also be a strategy to avoid the Winner's curse.
Chandelier or Rafter Bidding
A practice, especially by high-end art auctioneers, of raising false bids at crucial times in the bidding process in order to create the appearance of greater demand or to extend bidding momentum for a work on offer. To call out these nonexistent bids, auctioneers might fix their gaze at a point in the auction room that is difficult for the audience to pin down.
In the United Kingdom, this practice is legal on property auctions up to but not including the reserve price, and is also known as off-the-wall bidding.[44]
Collusion
Whenever bidders at an auction are aware of the identity of the other bidders there is a risk that they will form a "ring" and thus manipulate the auction result, a practice known as collusion. By agreeing to bid only against outsiders, never against members of the "ring", competition becomes weaker, which may dramatically affect the final price level. After the end of the official auction an unofficial auction will take place among the "ring" members. The difference in price between the two auctions will then be split among the members.
A ring can also be used to increase the price of an auction lot, in which the owner of the object being auctioned may increase competition by taking part in the bidding him or herself, but drop out of the bidding just before the final bid. In Britain and many other countries Rings and the bidding on one's own object are illegal. This form of a ring was used as a central plot device in an episode of the British television series Lovejoy (series 4, episode 3) in which the price of a watercolour by the (fictional) Jessie Webb is inflated in order that others by the same artist can be sold for more than their purchase price.
In an English auction a dummy bid is a bid made by a dummy bidder acting in collusion with the auctioneer or vendor, designed to deceive genuine bidders into paying more. In a First price auction a dummy bid is an unfavourable bid designed so as not to become the winning bid. (The bidder does not want to win this auction, but he or she wants to make sure to be invited to the next auction).
In Australia a dummy bid (shill, schill) is a criminal offence but a vendor bid or a co-owner bid below the reserve price is permitted, if clearly declared as such by the auctioneer. These are all official legal terms in Australia, but may have other meanings elsewhere. A co-owner is one of two or several owners (who disagree among themselves).
In Sweden and many other countries there are no legal restrictions, but it will severely hurt the reputation of an auction house that knowingly permits any other bids except genuine bids. If the reserve is not reached this should be clearly declared.
Suggested opening bid (SOB)
There will usually an estimate of what price the lot will fetch. In an ascending open auction it is considered important to get 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. This is due to the increase in the number of bidders attracted by the low SOB. When 50 bidders compete, the winning bid will be about twice as high as when only two bidders compete. Sometimes with an English auction there will be more than 50 bidders.
A chi-squared distribution shows many low bids but few high bids. Bids "show up together"; without several low bids there will not be any high bids.
Another approach to choosing an SOB: The auctioneer may achieve good success by asking the expected final sales price for the item, as this method suggests to the potential buyers the item's particular value. For instance, say an auctioneer is about to sell a $1,000 car at a sale. Instead of asking $100, hoping to entice wide interest (for who wouldn't want a $1,000 car for $100?), the auctioneer may suggest an opening bid of $1,000; although the first bidder may begin bidding at a mere $100, the final bid may more likely approach $1,000.
