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 AND MARKET DEMAND The aggregate demand curve, or AD curve, has similarities to, but differences from, the standard market demand curve. Both are negatively sloped. Both relate price and quantity. However, the market demand curve is negatively sloped because of the income and substitution effects and the aggregate demand curve is negatively sloped because of the real-balance, interest-rate, and net-export effects.
