Market foreclosure


Market foreclosure or vertical foreclosure is the production limitation put on a producing organization if either it is denied access to a supplier.

Examples

An examination of media markets showed that integrated operators are likely to exclude rival program services, and attempt to increase the barrier to entry in the market. Thus, effectively blocking some program services from the distribution networks of vertically integrated cable system operators.
In gasoline production, a vertically-integrated refinery can reduce competition through practices that constrain supply to retailers outside its network of related firms. Researchers have estimated that US wholesale gasoline prices have been raised by 0.2 to 0.6 cents per gallon due to the market power wielded by vertically integrated players in the industry.

Vertical integration without market foreclosure

Vertical integration does not always foreclose markets. Researchers reviewing plant and market data in the US cement and concrete industries over a 34-year span found that vertical integration led to lower prices and higher quantities for consumers, presumably because of production efficiencies from integration. This is contrary to what one would expect in a market experiencing foreclosure by players with market power. Similarly, a review of exclusive dealing practices in the Chicago beer market did not find foreclosure effects.
