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.

MARKET FAILURES Imperfections in the exchange process between buyers and sellers that prevent markets from efficiently allocating scarce resources. Market failures come in four varieties -- public goods, market control, externalities, and imperfect information. Market efficiency is achieved if the value of goods produced is equal to the value of foregone production. Markets fail when this efficiency condition is not achieved. Such failures can only be corrected by government intervention.
