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.

UNEMPLOYMENT RATE, MEASUREMENT PROBLEMS The official unemployment rate, which measures the proportion of the civilian labor force 16 years or older that is not engaged in productive activities but is actively seeking employment, might be either overstated or understated due to discouraged workers, part-time workers, and unreported legal or illegal employment. Taken together, these measurement problems suggest that the official unemployment rate is likely understated during business-cycle contraction and overstated during business-cycle expansions.
