Auction is one of the most important types of international trade.Auction mechanism is classified into four types in classical theory of auction.As development of E-Commerce and Economic,many new Combinatorial Auction mechanism has emerged,such as random nth-rice auction,GVA,SAA,AUSM, PSP,AkBA,iBundle,new auction mechanism has also been developed to prevent buyer false-name bidding,such as TPD,LDS,S-MAP.Random nth-price auction is designed to induce people to reveal theirvate preferences for a good.GVA is generally accepted as a effcient combinatorial auction mechanism.This paper adds to economic analysis a formal representation of the emotions evoked by auction process,specifically,the excitement and the frustration. Through building the monetary utility and the emotional utility,we analyze the different kind of risk bidder' synthetical utility.And we get when bidder in positive affective states were found to assume less risk.In this situations these bidder can get the maximum utility.Define the individual's propensity to bid;we further know the bidding strategy of the different riskers.We studie a common value auction in which a naive bidder competes against a rational bidder. According to the "naive-rational" bidding model,we analyze the bidders' optimal bidding.When the signal distribution is uniform,the naive's ex ante payoff is higher than the rational' ex ante.Further,the evolutionary equilibrium of proportion of bidder types exists in the auctions.The result shows that naive bidder will not eventually be driven from the auction,and "naive-rational" bidding exists forever.
