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.

GOVERNMENT CONSUMPTION EXPENDITURES AND GROSS INVESTMENT The official item in the National Income and Product Accounts maintained by the Bureau of Economics Analysis measuring government purchases undertaken by the government sector. Government consumption expenditures and gross investment averages between 15-20 percent of gross domestic product. As might be expected, this percentage tends to be ebb and flow with the political winds. Some political leaders prefer more government activity, others less. However, this percentage is even more dependent on military conflicts and wars that require massive government activity. The other official expenditures included in the National Income and Product Accounts are personal consumption expenditures, gross private domestic investment, and net exports of goods and services.
