Bidding Fee Auction
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. How it works Participants pay a fee to purchase bids. Each of the bids increases the price of the item by a small amount, such as one penny (0.01 USD, 1¢, or 0.01 GBP, 1p; hence the name of ...

All-pay Auction
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. As shown by Riley and Samuelson (1981), equilibrium bidding in an all pay auction with private information is revenue equivalent to bidding in a sealed high bid or open ascending price auction. In the simplest version, there is complete information. The Nash equilibrium is such that each bidder plays a mixed strategy and expected pay-offs are zero.Jehiel P, Moldovanu B (2006) Allocative and informational externalities in auctions and related mechanisms. In: Blundell R, Newey WK, Persson T (eds) Advances in Economics and Econometrics: Volume 1: Theory and Applications, Ninth World Congress, vol 1, Cambridge University Press, chap 3 The seller's expected revenue is equal to the value of the prize. However, some economic experiments and studies have shown that over-bidding is common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunk Cost
In economics and business decision-making, a sunk cost (also known as retrospective cost) is a cost that has already been incurred and cannot be recovered. Sunk costs are contrasted with '' prospective costs'', which are future costs that may be avoided if action is taken. In other words, a sunk cost is a sum paid in the past that is no longer relevant to decisions about the future. Even though economists argue that sunk costs are no longer relevant to future rational decision-making, people in everyday life often take previous expenditures in situations, such as repairing a car or house, into their future decisions regarding those properties. Bygones principle According to classical economics and standard microeconomic theory, only prospective (future) costs are relevant to a rational decision. At any moment in time, the best thing to do depends only on ''current'' alternatives. The only things that matter are the ''future'' consequences. Past mistakes are irrelevant. Any cos ...

Internet
The Internet (or internet) is the Global network, global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a internetworking, network of networks that consists of Private network, private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, Wireless network, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and Web application, applications of the World Wide Web (WWW), email, electronic mail, internet telephony, streaming media and file sharing. The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication.

Swoopo
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. Mechanics In order to participate in an auction, registered users had to first buy bids (called credits) before entering into an auction. For the US version of the site, credits cost $0.60 apiece and were sold in lots (called BidPacks) of 40, 75, 150, 400, and 1,000. Each credit was good for one bid. Standard auctions began with an opening price ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gambling
Gambling (also known as betting or gaming) is the wagering of something of Value (economics), value ("the stakes") on a Event (probability theory), random event with the intent of winning something else of value, where instances of strategy (game theory), strategy are discounted. Gambling thus requires three elements to be present: consideration (an amount wagered), risk (chance), and a prize. The outcome of the wager is often immediate, such as a single roll of dice, a spin of a roulette wheel, or a horse crossing the finish line, but longer time frames are also common, allowing wagers on the outcome of a future sports contest or even an entire sports season. The term "gaming" in this context typically refers to instances in which the activity has been specifically permitted by law. The two words are not mutually exclusive; ''i.e.'', a "gaming" company offers (legal) "gambling" activities to the public and may be regulated by one of many gaming control boards, for example, the ...

Fraud
In law, fraud is intent (law), intentional deception to deprive a victim of a legal right or to gain from a victim unlawfully or unfairly. Fraud can violate Civil law (common law), civil law (e.g., a fraud victim may sue the fraud perpetrator to avoid the fraud or recover monetary compensation) or criminal law (e.g., a fraud perpetrator may be prosecuted and imprisoned by governmental authorities), or it may cause no loss of money, property, or legal right but still be an element of another civil or criminal wrong. The purpose of fraud may be monetary gain or other benefits, such as obtaining a passport, travel document, or driver's licence. In cases of mortgage fraud, the perpetrator may attempt to qualify for a mortgage by way of false statements. Terminology Fraud can be defined as either a civil wrong or a criminal act. For civil fraud, a government agency or person or entity harmed by fraud may bring litigation to stop the fraud, seek monetary damages, or both. For cr ...

Shill Bidding
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. Shills can carry out their operations in the areas of media, journalism, marketing, politics, sports, confidence games, cryptocurrency, or other business areas. A shill may also act to discredit opponents or critics of the person or organization in which they have a vested interest. In most uses, ''shill'' refers to someone who purposely gives onlookers, participants or "marks" the impression of an enthusiastic customer independent of the seller, marketer or con artist, for whom they are secretly working. The person or group in league with the shill relies on crowd psychology to encourage other onlookers or audience members to do business with the seller or accept the ideas they are promoting. Shills may be employed by salespeople and professional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dollar Auction
The dollar auction is a non-zero sum sequential game explored by economist Martin Shubik to illustrate how a short-sighted approach to rational choice can lead to decisions that are, in the long-run, irrational. Shubik: 1971. Page 109 Play The setup involves an auctioneer who volunteers to auction off a dollar bill with the following rule: the bill goes to the winner; however, the second-highest bidder also loses the amount that they bid, making them the biggest loser in the auction. The winner can get a dollar for a mere 5 cents (the minimum bid), but only if no one else enters into the bidding war. However, entering the auction with a low bid may result in a problematic outcome. For instance, a player might begin by bidding 5 cents, hoping to make a 95-cent profit. They can be outbid by another player bidding 10 cents, as a 90-cent profit is still desirable. Similarly, another bidder may bid 15 cents, making an 85-cent profit. Meanwhile, the second bidder may attempt to conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Game Theory
Game theory is the study of mathematical models of strategic interactions. It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. Initially, game theory addressed two-person zero-sum games, in which a participant's gains or losses are exactly balanced by the losses and gains of the other participant. In the 1950s, it was extended to the study of non zero-sum games, and was eventually applied to a wide range of Human behavior, behavioral relations. It is now an umbrella term for the science of rational Decision-making, decision making in humans, animals, and computers. Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum games and its proof by John von Neumann. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathematical economics.
