| Abstract(in English) | To achieve a socially efficient allocation in Internet auctions, it is important to exclude insincere sellers, i.e., it is necessary to investigate unidentified sellers and share information on them. However, the first buyer (investigator) may suffer a loss if the seller is insincere, which discourages the buyer being an investigator. To solve this problem, we design auction protocols that motivate buyers to investigate unidentified sellers by determining an appropriate amount of payment. We prove that the buyers' truth telling is in equilibrium in this protocol. Moreover, experimental results show that the social surplus obtained by our protocol is close to an efficient allocation. |
