    Monopoly

    While this lesson on monopoly is not necessarily a "how to" guide for the monopolization of a market, it does provide insight into the nature and function of the monopoly market structure. We get a little insight into how a monopoly is created, and a lot of insight into what a monopoly does once it does have control of the market. Throughout this lesson, I'll me making snide comments about how inefficient monopoly is compared to more competitive markets.

    • The first unit of this lesson, One Firm, begins this lesson with a look at the nature of monopoly and how it is related to other market structures.
    • In the second unit, Revenue, we examine the revenue side of a market dominated by monopoly -- including total revenue, average revenue, and marginal revenue.
    • The third unit, Output, then looks at the profit-maximizing output production decision by a monopoly using assorted graphs and tables.
    • In the fourth unit, Evaluation, we analyze the profit-maximizing decision of monopoly in terms of profit, loss, efficiency, and short-run supply.
    • The fifth and final unit, Regulation, then closes this lesson by considering the role government plays in regulating monopoly.

    ADVERSE SELECTION

    An inefficient, bad, or adverse outcome of a market exchange that results because buyers and/or sellers make decisions based on asymmetric information. This commonly results in a market that exchanges a lesser quality good, what is termed the market for lemons. Two related problems resulting from asymmetric information are moral hazard and the principal-agent problem. Two methods of lessoning the problem of adverse selection are signalling and screening.
