JOINT PRODUCT: One of two goods that are produced jointly using the same resource--that is, the production of one good automatically triggers the production of the other. Also termed by-products or complements-in-production, a noted example is the production of two goods--beef and leather--from one resource--cattle. Another joint product example is lumber and sawdust--both produced from a single tree.

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.

GAINS FROM TRADE The combination of consumer surplus and producer surplus obtained by buyers and sellers when engaging in a market exchange. Gains from trade arise because buyers are typically willing and able to pay a higher price to purchase a good than what they end up paying and because sellers are typically willing and able to accept a lower price to sell a good than what they end up receiving. Both sides of the market exchange are thus better off, have a net gain in welfare, by making the trade. While all types of market exchanges generate gains from trade, this topic is perhaps most important for an understanding of international trade.
