Monopolies and Anti-Competitive Markets: Crash Course Economics #25

Summary

The video explains that monopolies can harm consumers by limiting competition, but some can be useful or efficient in particular circumstances. Whether a monopoly is harmful depends on how it arose, whether consumers have alternatives, and whether regulation is needed.

What makes a monopoly?

• A pure monopoly is a market with one seller and no close substitutes.
• A company’s power comes not only from its market share, but also from its ability to keep competitors out. Obstacles that make it difficult for new firms to enter are called barriers to entry.
• Barriers can include:
  • Government rules or licenses, especially when companies influence regulations in their favor. This is sometimes called crony capitalism.
  • Control of important resources, as De Beers once had with diamond mines.
  • High start-up costs, as with building a power plant.
• A firm can wield monopoly-like power without being the only seller. An oligopoly is a market dominated by a small number of firms.

The food-truck example contrasts open competition—where successful businesses attract new competitors—with a city that limits licenses and bans rival vendors. In the latter case, regulation protects the incumbent rather than serving consumers.

Why monopolies concern economists

With little or no competition, a monopoly can restrict output and charge higher prices. Most economists therefore support antitrust laws, which aim to preserve competition and prohibit monopolization and certain anticompetitive practices.

• The 1890 Sherman Act prohibited monopolization and attempted monopolization.
• The Department of Justice and Federal Trade Commission review mergers and can challenge conduct that threatens competition.
• Horizontal integration means combining companies that make similar products. Regulators may block a merger if it would give the combined company too much market power.
• Vertical integration means owning or controlling parts of a company’s supply chain. It is not automatically illegal, but mergers or agreements that restrict competitors’ access to suppliers can raise antitrust concerns.
• Examples discussed include the failed AT&T–T-Mobile merger, Microsoft’s pressure on computer makers to include Internet Explorer, and Toys “R” Us’s arrangements with toy suppliers.

When monopoly or exclusivity can be useful

• Patents temporarily give inventors exclusive rights to profit from a product or process. This can encourage innovation by helping companies recover research and development costs, especially in pharmaceuticals. Patents eventually expire—usually after about 20 years—allowing competitors to enter and often lowering prices.
• Natural monopolies occur when one large provider can supply a service more cheaply than multiple competing providers. Utilities such as electricity, water, natural gas, and sewage often fit this pattern because duplicating infrastructure would be costly. Governments may limit competition but regulate prices and fees to guard against abuse.
• Some high-market-share firms are non-coercive monopolies rather than natural monopolies. The video uses Nike in basketball shoes as an example: consumers have alternatives and are not forced to buy Nike, so its market share alone does not necessarily justify government intervention.
• The history of AT&T illustrates that a monopoly once treated as a natural monopoly can later be broken up. Following a 1974 antitrust lawsuit, AT&T was divided into seven regional companies, and competitors entered the market. This is an example of deregulation.

Pricing and price discrimination

• Price discrimination is charging different customers different prices for the same product.
• It works best when a firm can separate customers by their willingness to pay and has enough market power to prevent customers from simply switching to a competitor.
• Airlines, for example, may charge less to travelers who book early and more to those who book at the last minute. Age- or occupation-based discounts are other examples.
• Price discrimination is not limited to monopolies and is not always illegal. It can increase a firm’s profit compared with charging everyone one price.
• Historically, railroads’ differing freight rates advantaged some shippers and helped disadvantage smaller producers.

Overall lesson: Competition generally benefits consumers, but monopoly policy involves trade-offs. Some monopolies are created or maintained in ways that restrict competition and warrant intervention; others may promote innovation or make essential services cheaper to provide.
