INCOME, DEMAND DETERMINANT: One of the five demand determinants assumed constant when a demand curve is constructed, and that shift the demand curve when they change. Income affects demand differently for normal goods and inferior goods. A normal good, the name indicates, is affected by income much as you might expect. Additional income allows buyers to purchase more normal goods, thus demand increases with an increase in income. The demand for an inferior good is affected exactly opposite. An increase in income causes a decrease in the demand for an inferior good. Buyers decide to buy less of an inferior good when they have additional income.

    Oligopoly

    • The first unit of this lesson, A Few Firms, begins this lesson with a look at the nature of oligopoly and how it is related to other market structures.
    • In the second unit, Structure, we see how markets with a small number of large firms are structured.
    • The third unit, Behavior, then looks at some of activities undertaken by oligopoly that are not seen in other market structures.
    • In the fourth unit, Some Graphs, we use a few graphs to examine different ways that oligopoly firms interact in the production of output.
    • The fifth and final unit, Taking Stock, then closes this lesson by considering the good and the bad of oligopoly and why it is often prone to government scrutiny.

    SAVING SCHEDULE

    A table or chart that represents the relation between saving by the household sector and income. A saving schedule is commonly used for a basic, instructional presentation of aggregate saving activity by the household sector and is also used as a source of numbers for deriving the saving line. The key measures derived from the saving-income relation in the schedule are average propensity to save and marginal propensity to save. The consumption schedule is comparable, and more important, table for the relation between consumption and income.
