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.

THREE-SECTOR INJECTIONS-LEAKAGES MODEL A variation of the Keynesian injections-leakages model that includes the three domestic sectors--the household sector, the business sector, and the government sector. This model provides an alternative to the three-sector aggregate expenditures (Keynesian cross) analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps. Equilibrium is identified as the intersection between the S + T line and the I + G line. Two related variations are the two-sector injections-leakages model and the four-sector injections-leakages model.
