Vickrey auction
Vickrey auction, also known as a sealed-bid second-price auction. This is identical to the sealed first-price auction except that the winning bidder pays the second highest bid rather than their own. 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%).
维克瑞拍卖,也称为第二价格密封拍卖。这种拍卖方式与首价密封拍卖基本相同,区别仅在于胜出者需要支付的价格是第二高的报价,而不是他自己的报价。这与易趣网所使用的代理人竞价系统相似,在这个系统中,胜出者需要支付第二高的报价,再加上一个报价的增额(如10%)。
Although extremely important in auction theory, in practice Vickrey auctions are rarely used.
尽管这种方式在拍卖理论中占据重要地位,但在实际中,维克瑞拍卖方式却很少被使用。 |
