Collusion et possibilité d’entrée en aval dans une industrie verticalement intégrée

Eric Avenel, and Stéphane Caprice

Abstract

We analyze the impact of an entry threat at the downstream level on the ability of a pair of vertically integrated incumbents to collude. Entrants depend on the vertically integrated firms on the intermediate market for the purchasing of good. While the entry threat leaves collusion profits unchanged, we show that deviation profits are also unchanged and that profits are lower in the punishment periods. Consequently, an entry threat facilitates collusion, thus benefiting to incumbents.
