ABSTRACTION: Simplifying the complexities of the real world by ignoring (hopefully) unimportant details while doing economic analysis. Abstraction is often criticized because it's, well, it's JUST NOT REALISTIC. However, when done correctly (ignoring things that JUST DON'T MATTER), then the pursuit of knowledge is greatly enhanced by abstraction. For example, when travelling cross country along a high-speed interstate highway, a paper road map is a handy tool. It shows towns and cities along the way, the major intersections, rest stop locations, and other important points of interest. However, it ignores unimportant details. It doesn't realistically show the location of every tree, bush, or blade of grass. Why bother? This information won't enhance your road trip.

DISPOSABLE INCOME AND PERSONAL INCOME 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. 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 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 percent of personal income, which makes disposable personal income about 85 percent of personal income.

[What's This?]
Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway hoping to buy either a large, stuffed kitty cat or a cross-cut paper shredder. Be on the lookout for empty parking spaces that appear to be near the entrance to a store.
