Abstract

We put forward a new approach to mechanism design, and exemplify it via a new mechanism guaranteeing significant revenue in unrestricted combinatorial auctions. Our mechanism • succeeds in a new and very adversarial collusion model; • works in a new, equilibrium-less, and very strong solution concept; • benchmarks its performance against the knowledge that the players have about each other; • is computationally efficient and preserves the players ’ privacy to an unusual extent. 1
