Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Define a substitute good.

    Model answer

    A substitute is a product a consumer can buy instead of another because it satisfies the same need.

  2. 2

    Define a complementary good.

    Model answer

    A complement is a product bought and used alongside another, so demand for the two moves together.

  3. 3

    What happens to demand for a product when the price of a close substitute falls?

    Model answer

    Demand for the product falls, because some buyers switch to the alternative that is now cheaper.

  4. 4

    What happens to demand for printer ink if printers themselves become much cheaper?

    Model answer

    Demand for ink rises, because printers and ink are complements and more printers in use means more ink is bought.

  5. 5

    How does a rise in real household income usually affect demand for a normal good?

    Model answer

    Demand rises, because consumers can afford to buy more of it at any given price.

  6. 6

    What is an inferior good?

    Model answer

    An inferior good is one whose demand falls when consumer incomes rise, because buyers trade up to something they prefer.
