Does Vertical Integration Promote Downstream Incomplete Collusion? An Evaluation of Static and Dynamic Stability
This paper analyzes the impact of vertical integration on the static and dynamic stability of downstream incomplete collusion. It is shown that a vertical merger between an upstream firm and a downstream cartel or fringe firm promotes downstream collusion, under certain conditions on the market size. However, for low market concentration, a vertical merger with a cartel firm hinders collusion. Moreover, a welfare analysis shows that consumer surplus increases with the vertical merger because the merger partially eliminates the double marginalization problem.
