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.

NEAR-PUBLIC GOODS Goods characterized by nonrival consumption and the ability to exclude nonpayers. Near-public goods are one of four types of goods differentiated by consumption rivalry and nonpayer excludability. The other three goods are near-public (rival consumption and nonpayers can be excluded), public (nonrival consumption and nonpayers cannot be excluded), and common-property (rival consumption and nonpayers cannot be excluded). The ease of excluding of nonpayers means near-public goods can be exchanged through markets, but nonrival consumption means efficiency can only be achieved with government intervention.
