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.

PERFECT COMPETITION, EFFICIENCY Perfect competition is an idealized market structure that achieves an efficient allocation of resources. This efficiency is achieved because the profit-maximizing quantity of output produced by a perfectly competitive firm results in the equality between price and marginal cost. In the short run, this involves the equality between price and short-run marginal cost. In the long run, this is seen with the equality between price and long-run marginal cost at the minimum efficient scale of production.
