This paper characterizes the class of combinatorial auctions that have a particular form of Nash equilibrium. We refer to this class as Vickrey-reserve auctions. In such auctions, bidders pay at least their Vickrey–Clarke–Groves payments. A specific strategy profile studied by Bernheim and...

This paper considers some package auctions with known single-minded bidders. A single-minded bidder is interested in a unique bundle of goods and bids only for that bundle. We examine each bidder's incentive in Ausubel and Milgrom's (2002) ascending proxy auction and every bidder-optimal...

This paper investigates the perfect Bayesian equilibrium in an ascending-price core-selecting auction, which is recently used in some countriesʼ spectrum license auctions. We suppose that there are two identical items, two small bidders, and one large bidder. The small bidders demand only one...
