Study Notes

Market Structure

  • A market structure is an economic model of competition among businesses in the same industry
  • Economists use market structure to examine competition and classify markets based on how competitive they are
  • Different types of market structures influence how firms compete and how they set prices

Types of Market Structures

  • Perfect Competition
  • Monopoly
  • Monopolistic Competition
  • Oligopoly

Oligopoly

  • A market structure where a few sellers offer similar products

  • Less competitive than monopolistic competition

  • A few large firms dominate the market, holding a large percentage of total sales

  • High start-up costs limit the number of firms

  • Four major characteristics:

    • Few sellers, many buyers
    • Standardized or differentiated products
    • More control of prices
    • Limited freedom to enter or exit the market
  • In an oligopoly, firms have significant influence on the market's price.

  • Economists define an oligopoly when the four largest firms control at least 40% of the market.

  • The breakfast cereal industry is an example, with a few large manufacturers controlling a large share of the market.

  • Oligopolies can sell standardized or differentiated products.

  • Standardized products (e.g., steel) are often controlled by a few large firms

  • Differentiated products (e.g., breakfast cereals) use marketing strategies to compete

    • Examples of differentiation include brand name, service, or location.
  • Businesses in oligopolies have more influence on prices because decisions by one firm influence the entire market, e.g., price cuts by one manufacturer might cause similar cuts by competitors.

  • High start-up costs and patents create significant barriers to entry for new firms

  • Existing firms often have established brands and resources that make it challenging for new businesses to successfully enter the market, e.g., agreements with grocery stores to secure desirable shelf space.

  • Once established, even when a major company loses money, they may face difficulties in exiting the market because of the scale and complexity of their operations
