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.

UTILITY MEASUREMENT A quantification of the satisfaction of wants and needs achieved through the consumption of goods and services. In principle, utility measurement can take one of two forms: (1) cardinal, which is based on numerical values (1, 2, 3, etc.) and (2) ordinal which is based on rankings (first, second, third, etc.). While the hypothetical instructional analysis of utility relies on cardinal utility, ordinal utility is a more realistic way to measure satisfaction.
