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.

DECREASING RETURNS TO SCALE A given proportional change in all resources in the long run results in a proportional smaller change in production. Decreasing returns to scale exists if a firm increases ALL resources--labor, capital, and other inputs--by a given proportion (say 10 percent) and output increases by less than this proportion (that is, less than 10 percent). This is one of three returns to scale. The other two are increasing returns to scale and constant returns to scale.
