NEED: This is often thought of as a physiological or biological requirement for maintaining life, such as the need for air, water, food, shelter, and sleep. Satisfaction is achieved by fulfilling needs. Physiological needs should be contrasted with psychological wants that make life more enjoyable but are not necessary to stay alive. However, when push comes to shove, and the nitty gets down to the gritty, it matters very little to markets if people need goods or want goods, so long as they are motivated to satisfy them. This motivation is what drives economic activity.

COMPETITION: In general, the actions of two or more rivals in pursuit of the same objective. In the context of markets, the specific objective is either selling goods to buyers or alternatively buying goods from sellers. Competition tends to come in two varieties -- competition among the few, which is market with a small number of sellers (or buyers), such that each seller (or buyer) has some degree of market control, and competition among the many, which is a market with so many buyers and sellers that none is able to influence the market price or quantity exchanged.

MARGINAL COST

The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost (MC) indicates how much total cost changes for a given change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. It is found by dividing the change in total cost (or total variable cost) by the change in output. Marginal cost is one of four cost concepts used in short-run production analysis. The other three are average total cost, average fixed cost, and average variable cost.

This isn't me! What am I?

The word "fiscal" is derived from a Latin word meaning "moneybag."
"Many people think that if they were only in some other place, or had some other job, they would be happy. Well, that is doubtful. So get as much happiness out of what you are doing as you can and don't put off being happy until some future date. "
