PERSONAL INCOME AND DISPOSABLE INCOME: Personal income (PI) is the total income received by the members of the domestic household sector, which may or may not be earned from productive activities during a given period of time, usually one year. Disposable income (DI) is the total income that can be used by the household sector for either consumption or saving during a given period of time, usually one year. Disposable income is after-tax income that is officially calculated as the difference between personal income and personal tax and nontax payments. In the numbers game, personal tax and nontax payments are about 15% of personal income, which makes disposable personal income about 85% of personal income.

PHENOMENON:

An event or action that is subject to investigation, analysis, and explanation using the scientific method. Phenomena are the sorts of things that science seeks to explain. They can be common events, like the blowing wind, or unusual, like the extinction of the dinosaurs.
While the term phenomenon might entice thoughts of UFOs, ghosts, and mutant three-headed turtles, it really applies to any type of event or action. These events can be extraordinary or mundane. They can be unusual or common place.

The types of events falling under the heading of phenomena and subject to scientific study include the sun rising, the stock market falling, a person talking, a volcano erupting, a basketball bouncing, a star exploding, and a bird flying. Some of these events might not seem appropriately suited to be called phenomena because they are quite ordinary.

The Extraordinary

Science is definitely interested in explaining unusual and extraordinary events. If a glowing, three-dimensional, translucent image of Abraham Lincoln playing badminton with Issac Newton suddenly appears on the front lawn of the White House, then science would certainly seek an explanation. Scientists salivate profusely at the prospect of explaining the occurrence of exceptional events. Doing so pushes forth the frontiers of science. It reveals possible deficiencies in existing theories and avenues for improvement.

The Great Depression of the 1930s, for example, revealed flaws in the existing classical economic explanation of the macroeconomy and induced economists to push forth the theoretical boundaries of economic science.

The Ordinary

Science, however, seeks to explain ordinary and mundane events, as well. It is also interested in explaining the glow of fireflies, the flight of a badminton shuttlecock, and the growth of grass on the front lawn of the White House. Explaining common events means that a theory works, that it has captured the essential laws of nature.

The same theory that might explain the catastrophic downturn of the Great Depression also needs to explain an increase in the unemployment rate from 5.1 percent to 5.2 percent. If it fails to explain the ordinary, then a theory has no chance of explaining the extraordinary.

[What's This?]

Today, you are likely to spend a great deal of time surfing the Internet looking to buy either a green and yellow striped sweater vest or a Boston Red Sox baseball cap. Be on the lookout for strangers with large satchels of used undergarments.
