COMPLEMENT: Two goods that "go together," either in consumption or production. In terms of demand, a complement-in-consumption is one of two goods that are consumed together such that an increase in the price of one good leads to a decrease in demand and a leftward shift in the demand curve for the other good. If the demand of good 1 decreases as the price of good 2 increases, the goods are complements-in-consumption. In terms of supply, a complement-in-production is one of two goods that are produced jointly using the same resources, such that an increase in the price of one good leads to an increase in supply and a rightward shift in the supply curve for the other good. If the supply of good 1 increases as the price of good 2 increases, the goods are complements-in-production.

    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.

    SHORT RUN, MICROECONOMICS

    In terms of the microeconomic analysis of production and supply, a period of time in which at least one input under the control of a firm used in the production process is variable and at least one input is fixed. In the short run, the variable input is usually labor and the fixed input is capital. The short-run analysis of production reveals the law of diminishing marginal returns and provides an understanding of the upward-sloping supply curve and the law of supply. This is one of four production time periods used in the study of microeconomics. The other three are long run, very long run, and very short run (or market period). The short run is also a time period designation used in the macroeconomic analysis of business cycles.
