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.

INVESTMENT LINE A graphical depiction of the relation between investment expenditures by the business sector and the economy's aggregate level of income or production. This relation plays a key role in the study of Keynesian economics. A investment line is characterized by vertical intercept, which indicates autonomous investment, and slope, which is the marginal propensity to invest and indicates induced investment. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the investment line onto the consumption line, then adding government purchases and net exports to this stack.
