Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is a normal good?

    Model answer

    A normal good is one for which demand increases as consumers' incomes rise and falls as their incomes fall.

  2. 2

    What is an inferior good?

    Model answer

    An inferior good is one for which demand falls as consumers' incomes rise, because they can afford to switch to something they prefer.

  3. 3

    Give two examples of inferior goods and explain why they qualify.

    Model answer

    Supermarket value-range food and second-hand clothing are inferior goods, because as households become better off they move to branded and new alternatives.

  4. 4

    What is a luxury good?

    Model answer

    A luxury good is a normal good whose demand rises proportionately more than income, so spending on it grows faster than earnings do.

  5. 5

    Give three examples of luxury goods.

    Model answer

    Foreign holidays, restaurant meals and designer clothing are all luxuries in this sense.

  6. 6

    Explain the difference between a normal good and a luxury good.

    Model answer

    Demand for both rises with income, but for a luxury it rises proportionately faster, so a luxury's income elasticity is above one while an ordinary normal good's is between zero and one.
