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.

PLASTIC MONEY A slang phrase for credit cards, especially when such cards used to make purchases. The "plastic" portion of this term refers to the plastic construction of credit cards, as opposed to paper and metal of currency. The "money" portion is an erroneous reference to credit cards as a form of money, which they are not. Although credit cards do facilitate transactions, because they are a liability rather than an asset, they are not money and not part of the economy's money supply.
