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.

KINKED-DEMAND CURVE A demand curve with two distinct segments which have different elasticities that join to form a corner or kink. The primary use of the kinked-demand curve is to explain price rigidity in oligopoly. The two segments are: (1) a relatively more elastic segment for price increases and (2) a relatively less elastic segment for price decreases. The relative elasticities of these two segments is based on the interdependent decision-making of oligopolistic firms.
