POLITICAL BUSINESS CYCLE: The notion that a business cycle is caused by elected government leaders who manipulate the economy to achieve personal political goals -- that is, to remain in office. The leaders stimulate the economy leading up to an election, creating a business-cycle expansion that ensures (they hope) their re-election, then induce a business-cycle contraction after the election to correct problems created by pre-election stimulation.

    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.
