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.

AGGREGATE DEMAND SHIFTS Changes in the aggregate demand determinants cause the aggregate demand curve to shift. The mechanism is comparable to that for market demand determinants and market demand. There are two alternatives--an increase in aggregate demand and a decrease in aggregate demand. An increase in spending by any of the four sectors--household, business, government, and foreign--shifts the aggregate demand curve to right. A decrease in spending by these four sectors shifts the aggregate demand curve to left.
