Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What does income elasticity of demand (YED) measure?

    Model answer

    The responsiveness of quantity demanded to a change in consumer income.

  2. 2

    What do the two components of the YED formula represent?

    Model answer

    The numerator represents the percentage change in quantity demanded; the denominator represents the percentage change in income.

  3. 3

    What type of good is indicated by a positive income elasticity of demand?

    Model answer

    A normal good, where demand increases as income rises.

  4. 4

    If YED is negative, what does this indicate about the product?

    Model answer

    It is an inferior good, where demand falls as income rises.

  5. 5

    At what value of YED does demand become income elastic?

    Model answer

    When YED is greater than 1, meaning demand is highly responsive to income changes.

  6. 6

    What range of YED values indicates income inelastic demand?

    Model answer

    Between 0 and 1, meaning demand is relatively unresponsive to income changes.
