First-best collusion without communication

Abstract

I study a 2-bidder infinitely repeated IPV first-price auction without transfers, communication, or public randomization, where each bidderʼs valuation can assume, in each of the (statistically independent) stage games, one of three possible values. Under certain distributional assumptions, the following holds: for every ϵ>0 there is a nondegenerate interval Δ(ϵ)⊂(0,1), such that if the biddersʼ discount factor belongs to Δ(ϵ), then there exists a Perfect Public Equilibrium with payoffs ϵ-close to the first-best payoffs.
