RATE OF RETURN: The ratio of the additional annual income or profit generated by an investment to the cost of the investment. Here's a simple example, although the calculations are usually a great deal more involved for actual investments. If the cost of constructing a new factory is $10 million and it gives you an extra $1 million in profit each year, then its rate of return is 10 percent.

    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.
