Abstract

This paper develops a new ascending-price multi-unit auction protocol that has the following characteristics: (i) it has an open format, and (ii) sincere bidding is an equilibrium strategy even if the marginal values of each agent can increase and agents can submit false-name bids. False-name bids are bids submitted under fictitious names such as multiple e-mail addresses, which can be done easily on the Internet. This is the first protocol that has both of these characteristics. Our simulation results indicate that the developed protocol obtains a social surplus close to Pareto efficient.
