Auction theory is an applied branch of economics which deals with how people act in auction markets and researches the properties of auction markets. There are many possible designs (or sets of rules) for an auction and typical issues studied by auction theorists include the efficiency of a given auction design, optimal and equilibrium bidding strategies, and revenue comparison. Auction theory is also used as a tool to inform the design of real-world auctions; most notably auctions for the privatisation of public-sector companies or the sale of licenses for use of the electromagnetic spectrum. ==General idea== Auctions take many forms but always satisfy two conditions: # They may be used to sell any item and so are ''universal'', also # The outcome of the auction does not depend on the identity of the bidders; i.e., auctions are ''anonymous''. Most auctions have the feature that participants submit ''bids'', amounts of money they are willing to pay. ''Standard'' auctions require that the winner of the auction is the participant with the highest bid. A ''nonstandard'' auction does not require this (e.g., a lottery). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「auction theory」の詳細全文を読む スポンサード リンク
