Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What are diseconomies of scale?

    Model answer

    Diseconomies of scale are the rise in unit cost that occurs when a business grows too large. Total costs begin to rise faster than output.

  2. 2

    How do communication problems cause diseconomies of scale?

    Model answer

    A large business has many levels through which a message must pass. Instructions are distorted or delayed, so mistakes and duplication increase.

  3. 3

    How do coordination problems cause diseconomies of scale?

    Model answer

    Managers of a large business cannot see everything happening across its sites. Departments duplicate work and pull in different directions.

  4. 4

    How does poor motivation cause diseconomies of scale?

    Model answer

    An employee in a very large organisation feels anonymous and unimportant. Effort falls, absence rises and output per worker declines.

  5. 5

    Give three problems caused by diseconomies of scale.

    Model answer

    Unit costs rise, decisions become slower and quality often falls. Industrial relations also deteriorate as staff feel remote from management.

  6. 6

    How can a large business reduce its diseconomies of scale?

    Model answer

    A large business can decentralise decisions to smaller divisions with their own accountability. A flatter structure and better communication systems also help.
