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.

BUSINESS CYCLE PHASES The recurring, but irregular, pattern of business cycles can be divided into two basic phases--expansion and contraction. An expansion is a period of increasing economic activity and a contraction is a period of declining economic activity. These two phases are marked by two transitions. The transition from expansion to contraction is termed a peak and the transition from contraction to expansion is termed a trough. The early portion of an expansion is often referred to as a recovery.
