Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is an economic good?

    Model answer

    A good that is scarce relative to the demand for it, so using it carries an opportunity cost and it commands a price.

  2. 2

    What makes a good a free good?

    Model answer

    It is unlimited in supply relative to demand, so consuming a unit of it has no opportunity cost and its price is zero.

  3. 3

    What is an example of a free good, and why is clean air not always one?

    Model answer

    Sunlight is a free good; clean air stops being free once pollution makes it scarce, because supplying it then uses up resources that have other uses.

  4. 4

    State the economic problem in a single sentence.

    Model answer

    Human wants are unlimited but the resources available to satisfy them are finite, so choices about how resources are used must be made.

  5. 5

    What is the difference between a need and a want?

    Model answer

    A need is something required for survival, such as food, water or shelter, while a want is something desired but not essential.

  6. 6

    Why does scarcity force every society to answer three basic questions?

    Model answer

    Because limited resources cannot meet all wants, society must decide what to produce, how to produce it and for whom it is produced.
