Vertical Integration, Raising Rivals’ Costs and Upstream Collusion
This paper analyzes the impact vertical integration has on upstream collusion when the price of the input is linear. As a first step, the paper derives the collusive equilibrium that requires the lowest discount factor in the infinitely repeated game when one firm is vertically integrated. It turns out this is the joint-profit maximum of the colluding firms. The discount factor needed to sustai...
متن کاملElectricity Retail Regulation in a Context of Vertical Integration: the Debate on Regulated Tariffs
The deregulation of power markets gave origin to a new activity: the retail business. Although it should, together with generation, be opened to competition, its implementation has been usually postponed to the last stages of the liberalization process. The diversity of situations that can be found in the international experience illustrates the lack of consensus about the appropriate design of...
متن کاملDynamic downstream collusion with secret vertical contracts
We consider dynamic, infinitely repeated downstream price competition. In every period, a retailer cannot observe the contract that the competing retailer offers to a joint supplier. We find that even though contracts are secret, they enable retailers to collude. The more the retailers and the supplier care about future profits, retailers obtain a higher share of the monopoly profits. We also f...
متن کاملSustaining Collusion under Economic Integration
In this paper, we aim at investigating from a game theory perspective whether trade liberalization can promote a collusive intra-industry trade and whether such a collusive trade is always socially desirable compared to the autarchy solution. We show that, under Cournot competition, economic integration is anti-competitive if collusive trade is a possible outcome of the repeated game; under pri...
متن کاملDo Vertical Mergers Facilitate Upstream Collusion?∗
In this paper we investigate the impact of vertical mergers on upstream firms’ ability to sustain collusion. We show in a number of models that the net effect of vertical integration is to facilitate collusion. Several effects arise. When upstream offers are secret, vertical mergers faciliate collusion through the operation of a foreclosure effect: Cheating unintegrated firms can no longer prof...
