Abstract

We study the welfare impact of enforcing a competitive behavior from an unregulated fringe competing with a regulated dominant operator with imperfectly differentiated goods. The fringe is potentially collusive but may be supervised by a competition authority. We show that the complementarity/substitutability between regulation and competition policy strongly depends on the nature of the market interaction. Forcing the fringe to adopt a competitive behavior always benefits consumers. However, it also affects the amount of subsidy that must be provided to the regulated firm for cost-reimbursement purposes, which has a social cost when public funds are costly. With complements, antitrust intervention is always welfare-improving. It is also preferable with weak substitutes but is detrimental to welfare for strong substitutes.
