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.

LEAKAGES LINE A graphical representation of the relation between the level of aggregate production and one or more leakages. The three leakages (non-consumption uses of the income generated from aggregate production) are saving, taxes, and imports. The leakages line sequentially adds, or layers, each of these three uses of income depending on the number of sectors used in the analysis (two, three, or four). The slope of the leakages line depends on which if any of the uses of income are induced by aggregate production. The leakages line is combined with the injections line (containing investment expenditures, government purchases, and exports) in the Keynesian injections-leakages model.

GRAY SKITTERY
[What's This?]
Today, you are likely to spend a great deal of time driving to a factory outlet seeking to buy either one of those memory foam pillows or a remote controlled train set. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
