Meaning
Competitive exclusion occurs when a dominant firm restricts the access of rivals to essential inputs or distribution channels. Antitrust regulators investigate market foreclosure to determine if a vertical merger or an exclusive dealing arrangement harms the competitive process. This condition arises when a supplier refuses to sell to a downstream competitor or a retailer refuses to carry a competing brand.
Such actions can raise the costs of rivals or deny them the scale necessary to remain viable.
Access Restriction
Denying competitors the ability to reach customers effectively reduces the overall number of choices in a given category. Market foreclosure often involves long-term contracts that lock up the most efficient distributors or the most desirable retail space.
Vertical Integration
A company that operates at multiple levels of the supply chain can use its position to disadvantage firms that only operate at one level. While vertical integration can improve efficiency, it may lead to market foreclosure if the integrated firm prioritizes its own subsidiaries over more efficient independent rivals. This strategy forces competitors to build their own alternative supply chains at great expense.
Economic Impact
The reduction in competition typically leads to higher prices for consumers and slower rates of innovation. Proving market foreclosure requires a thorough analysis of the available alternatives and the barriers to entry in the affected sector. This analysis provides the justification for regulatory intervention or the imposition of conduct remedies.
