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.

MARGINAL UTILITY-PRICE RATIO The ratio of the marginal utility obtained from consuming a good to the price of the good. This ratio is particularly important in determining consumer equilibrium, which is reached when the marginal utility-price ratios are the same for all goods. Equality between all marginal utility-price ratios is the rule of consumer equilibrium which is satisfied with utility maximization.
