A present value of revenues auction, sometimes called a least present value of revenues auction, is a method of awarding contracts in which the bids are for the total present value of cash flows from the project. The lowest bid wins, and the winner collects user fees until the present value of user fees equals their bid. [1] This system has been proposed for private highway construction.[ citation needed ]
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.
eBay Inc. is an American multinational e-commerce corporation based in San Jose, California, that facilitates consumer-to-consumer and business-to-consumer sales through its website. eBay was founded by Pierre Omidyar in 1995, and became a notable success story of the dot-com bubble. eBay is a multibillion-dollar business with operations in about 32 countries, as of 2019. The company manages the eBay website, an online auction and shopping website in which people and businesses buy and sell a wide variety of goods and services worldwide. The website is free to use for buyers, but sellers are charged fees for listing items after a limited number of free listings, and again when those items are sold.
The winner's curse is a phenomenon that may occur in common value auctions, where all bidders have the same value for an item but receive different private signals about this value and wherein the winner is the bidder with the most optimistic evaluation of the asset and therefore will tend to overestimate and overpay. Accordingly, the winner will be "cursed" in one of two ways: either the winning bid will exceed the value of the auctioned asset making the winner worse off in absolute terms, or the value of the asset will be less than the bidder anticipated, so the bidder may garner a net gain but will be worse off than anticipated. However, an actual overpayment will generally occur only if the winner fails to account for the winner's curse when bidding.
An online auction is an auction which is held over the internet. Like auctions in general, online auctions come in a variety of types like ascending English auctions, descending Dutch auctions, first-price sealed-bid, Vickrey auctions and others, which are sometimes not mutually exclusive.
Pay-per-click (PPC) is an internet advertising model used to drive traffic to websites, in which an advertiser pays a publisher when the ad is clicked.
A Vickrey auction or sealed-bid second-price auction (SPSBA) 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 private highway is a highway owned and operated for profit by private industry. Private highways are common in Asia and Europe; in addition, a few have been built in the United States on an experimental basis. Typically, private highways are built by companies that charge tolls for a period while the debt is retired, after which the highway is turned over to government control. This allows governments to fulfill immediate transportation needs despite their own budget constraints, while still retaining public ownership of the roads in the long term.
In common valueauctions the value of the item for sale is identical amongst bidders, but bidders have different information about the item's value. This stands in contrast to a private value auction where each bidder's private valuation of the item is different and independent of peers' valuations.
Gmarket is an e-commerce website based in South Korea. The company was founded in 2000 as a subsidiary of Interpark and was acquired by eBay in 2009.
Hi-Living is a Korean online auction website and shopping mall where people from all around the world buy and sell goods and services.
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 theory is an applied branch of economics which deals with how bidders act in auction markets and researches how the features of auction markets 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 conference of the price between the buyer and seller is an economic equilibrium. Auction theorists design rules for auctions to address issues which can lead to market failure. The design of these rulesets encourages optimal bidding strategies among 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.”
In economics and game theory, an all-pay auction is an auction in which every bidder must pay regardless of whether they win the prize, which is awarded to the highest bidder as in a conventional auction.
Swoopo was a bidding fee auction site where purchased credits were used to make bids. Prior to changing its name to Swoopo in 2008, the website was called Telebid. In March 2011, Swoopo's website became inaccessible, and a notice page claimed that Swoopo was experiencing "technical issues." In February 2012, DealDash obtained the domain name for Swoopo.com. The penny auction was invented by Lloyd Liske and William Buckell when the site was first created and known as telebid.com. At that time the site received bids by phone and charged to transfer their bids to the internet site. This is where the format of paying to place a bid started.
Market design is a practical methodology for creation of markets of certain properties, which is partially based on mechanism design. In some markets, prices may be used to induce the desired outcomes — these markets are the study of auction theory. In other markets, prices may not be used — these markets are the study of matching theory.
Consumer to consumer (C2C) markets provide an innovative way to allow customers to interact with each other. Traditional markets require business to customer relationships, in which a customer goes to the business in order to purchase a product or service. In customer to customer markets, the business facilitates an environment where customers can sell goods or services to each other. Other types of markets include business to business (B2B) and business to customer (B2C).
DealDash is a bidding fee auction site.
