NEEDS: This are 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.

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.

"I learned about the strength you can get from a close family life. I learned to keep going, even in bad times. I learned not to despair, even when my world was falling apart. I learned that there are no free lunches. And I learned the value of hard work. " -- Lee Iacocca
