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.

An increase in consumer confidence causes an increase (upward shift) of the aggregate expenditures line. A decrease in consumer confidence causes a decrease (downward shift) of the aggregate expenditures line. Other notable aggregate expenditures determinants include interest rates, federal deficit, inflationary expectations, and exchange rates.
