LABOR FORCE: The total number of people willing and able to exert mental and/or physical efforts in productive activities. In principle, this is everyone 16 years of age and over who is willing and able to work. In practice, it includes the sum of anyone over 16 years who is employed or unemployed but actively seeking a job. The labor force is essentially a more technical term for the economy's labor supply.

    Cost

    • The first unit of this lesson, The Basics, begins this our study with a review of the opportunity cost notion and how it relates to business activity.
    • In the second unit, Three Totals, we take a look at the three total cost measures, including total cost, total variable cost, and total fixed cost.
    • The third unit, Four More Measures, then presents four additional cost measures -- average total cost, average variable cost, average fixed cost, and marginal cost.
    • In the fourth unit, Long-Run Cost, we examine how scale economies and diseconomies affect cost in the long run.
    • The fifth and final unit, Previewing Supply, then closes this lesson by previewing the importance of cost, especially marginal cost, to the supply decision by a firm.
