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 FACTOR COST CURVE A curve that graphically represents the relation between marginal factor cost incurred by a firm for hiring an input and the quantity of input employed. A profit-maximizing firm hires the quantity of input found at the intersection of the marginal factor cost curve and marginal revenue product curve. The marginal factor cost curve for a firm with no market control is horizontal. The marginal factor cost curve for a firm with market control is positively sloped and lies above the average factor cost curve.
