Auctions are among the oldest methods of selling items, with recorded occurrences as early as 500 BC.

  • The First Price Auction: In a first price auction, each bidder simultaneously writes down his name and a number on a slip of paper and submits the paper to the auctioneer. The auctioneer turns over all the of the papers, the bidder who wrote down the highest number is given the item and pays the amount that is written on his slip. Under certain assumptions, this procedure is identical to the so-called Dutch auction, or descending price auction. The price begins at some incredibly high amount and drops at a predetermined rate, for example 10 cents per second. The auction ends when one of the bidders presses a button which keeps the price from falling further and pays an amount of money, equal to the posted price when he stopped the clock. The other bidders receive nothing and pay nothing.
  • The second price auction: In second price auction, each bidder simultaneously writes down his name and a number on a slip of paper and submits the papers to an auctioneer. The auctioneer turns over all the papers and the bidder who wrote down the highest number is given the item and pays the second highest amount that was written by other bidders. Under certain conditions and assumptions the auction is similar to that of Button auction and auction of fish in Japan. The bidders will have their names on a board with lights next to their names. The auction begins with zero and ascends at a predetermined rate. As long as the lights next to the name of a bidder is still on, the participant is still in the auction. Each bidder can press a button which will turn off the lights. The last bidder to be in the auction with lights on will win the item and pays the price at which his previous bidder dropped out. This is similar to the selling procedure on eBay.
