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.

UTILITY MEASUREMENT A quantification of the satisfaction of wants and needs achieved through the consumption of goods and services. In principle, utility measurement can take one of two forms: (1) cardinal, which is based on numerical values (1, 2, 3, etc.) and (2) ordinal which is based on rankings (first, second, third, etc.). While the hypothetical instructional analysis of utility relies on cardinal utility, ordinal utility is a more realistic way to measure satisfaction.
