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.

INTERCEPT, SAVING LINE The intercept of the saving line indicates autonomous saving, saving that does not depend on the level of income or production. This can be thought of as the baseline level of saving that would be undertaken if income falls to zero. Autonomous saving is affected by the consumption expenditures determinants, which cause a change in the intercept and a shift of the saving line. The value of the intercept of the saving line is the negative of the value of the intercept of the consumption line.

[What's This?]
