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: An ideal market structure characterized by a large number of small firms, identical products sold by all firms, freedom of entry into and exit out of the industry, and perfect knowledge of prices and technology. This is one of four basic market structures. The other three are monopoly, oligopoly, and monopolistic competition. Perfect competition is an idealized market structure that's not observed in the real world. While unrealistic, it does provide an excellent benchmark that can be used to analyze real world market structures. In particular, perfect competition efficiently allocates resources.
