Collusion-proof and fair auctions

Martin Hagen ()

Economics Letters, 2019, vol. 185, issue C

Abstract: In the standard auction model, we provide a necessary and sufficient condition on the value domain under which non-trivial mechanisms exist that satisfy group strategy-proofness and symmetry. In particular, this condition is satisfied (violated) if values are drawn from a finite set (an interval).
