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.

NET EXPORTS LINE A graphical depiction of the relation between net exports attributed to the foreign sector and the economy's aggregate level of income or production. This relation plays a minor, but growing role in the study of Keynesian economics. A net exports line is characterized by vertical intercept, which indicates autonomous net exports, and slope, which is the negative of the marginal propensity to import and indicates induced net exports. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the net exports line onto the consumption line, after adding investment expenditures and government purchases.
