    The Firm

    This lesson investigates the nature of firms, especially those in the U.S. economy, including what they are, what they do, and how they operate. Paying careful attention to this lesson is no guaranteed that Duncan will end up with a multi-billion dollar "dot-com" business, but it won't hurt.

    • The first unit of this lesson, Organizing Production, gets us started with an overview of what firms are and their primary function in the economy -- which is production.
    • In the second unit, Objectives, we take a closer look at what motivates firms, especially the pursuit of profit.
    • The third unit, Legal Types, examines the most common legal forms of business firms, including proprietorships, partnerships, and corporations.
    • The fourth unit, U.S. Firms, investigates firms in the United States by the numbers -- including how many, what they are, what they produce.
    • The fifth and final unit, The Bigger Picture, then closes this lesson by discussing the role firms play in the grand economic scheme of things.
