Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is meant by the degree of competition in a market?

    Model answer

    The degree of competition describes how much rivalry there is between suppliers, ranging from perfect competition at one extreme to monopoly at the other.

  2. 2

    Name the four market structures used to describe the degree of competition.

    Model answer

    They are perfect competition, monopolistic competition, oligopoly and monopoly.

  3. 3

    Name four features used to distinguish one market structure from another.

    Model answer

    They are distinguished by the number of firms, how similar or differentiated the products are, how easily new firms can enter, and how much control firms have over price.

  4. 4

    What is meant by a barrier to entry?

    Model answer

    A barrier to entry is anything that makes it difficult or expensive for a new firm to start supplying a market.

  5. 5

    Give four examples of barriers to entry.

    Model answer

    Very high start-up costs, patents held by existing firms, established brand loyalty, and control of the distribution network are all barriers to entry.

  6. 6

    How do economies of scale act as a barrier to entry?

    Model answer

    An established firm's low unit cost lets it charge a price a small newcomer cannot match, so entering profitably would require investing on the same very large scale immediately.
