Principles of Economics

Definition

The relevant market is a key concept in antitrust analysis, defining the scope of competition that is considered when evaluating the potential anti-competitive effects of a business practice or merger. It encompasses the products or services that are reasonable substitutes for one another from the consumer's perspective, as well as the geographic area where these substitutes are available.

5 Must Know Facts For Your Next Test

  1. The relevant market is a crucial component in determining whether a firm has monopoly power or if a merger will substantially lessen competition.
  2. Defining the relevant market involves identifying the products or services that are reasonably interchangeable from the consumer's perspective, as well as the geographic area where these substitutes are available.
  3. The product market considers factors such as product characteristics, price, and intended use, while the geographic market looks at transportation costs, consumer preferences, and the ability of consumers to switch to alternative suppliers.
  4. A narrow relevant market definition can increase the likelihood of finding monopoly power or anti-competitive effects, while a broader definition may make it more difficult to establish these concerns.
  5. Regulators often use the hypothetical monopolist test to determine the relevant market, which asks whether a hypothetical monopolist could profitably impose a small but significant and non-transitory increase in price (SSNIP).

Review Questions

  • Explain the significance of the relevant market in antitrust analysis and how it is determined.
    • The relevant market is a fundamental concept in antitrust analysis, as it defines the scope of competition that is considered when evaluating the potential anti-competitive effects of a business practice or merger. Determining the relevant market involves identifying the products or services that are reasonable substitutes for one another from the consumer's perspective, as well as the geographic area where these substitutes are available. This is crucial for assessing whether a firm has monopoly power or if a merger will substantially lessen competition, as a narrower relevant market definition can increase the likelihood of finding these concerns, while a broader definition may make it more difficult to establish them. Regulators often use the hypothetical monopolist test, which considers whether a hypothetical monopolist could profitably impose a small but significant and non-transitory increase in price, to define the relevant market.
  • Describe the factors that are considered when defining the product market and the geographic market within the relevant market.
    • When defining the relevant market, two key components are the product market and the geographic market. The product market refers to the set of products or services that are considered close substitutes by consumers and thus compete with one another. Factors considered in determining the product market include product characteristics, price, and intended use. The geographic market is the area in which the sellers of the relevant product operate and to which buyers can practicably turn for supplies of the relevant product. Factors considered in defining the geographic market include transportation costs, consumer preferences, and the ability of consumers to switch to alternative suppliers. The interplay between the product market and the geographic market is crucial in establishing the boundaries of the relevant market, which is then used to assess the potential for monopoly power or anti-competitive effects.
  • Analyze how the definition of the relevant market can impact the assessment of monopoly power or the potential for a merger to substantially lessen competition.
    • The definition of the relevant market is a critical determinant in the assessment of monopoly power or the potential for a merger to substantially lessen competition. A narrower relevant market definition can increase the likelihood of finding that a firm has monopoly power or that a merger will have anti-competitive effects, as it limits the scope of competition considered. Conversely, a broader relevant market definition may make it more difficult to establish these concerns, as it includes a wider range of substitutes that consumers can turn to. Regulators often use the hypothetical monopolist test, which considers whether a hypothetical monopolist could profitably impose a small but significant and non-transitory increase in price, to define the relevant market. The outcome of this test can significantly impact the antitrust analysis and the ultimate determination of whether a firm has monopoly power or if a merger will substantially lessen competition. Therefore, the definition of the relevant market is a crucial step in the antitrust evaluation process, as it directly shapes the assessment of potential anti-competitive effects.
