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.

EFFICIENT INFORMATION SEARCH A comparison between the cost of acquiring information and the benefit generated by the information such that it is not possible to increase welfare or well being by acquiring any more of any less information. Efficient information search is achieved by equating the marginal cost of search with the benefit of search. This efficiency is comparable to the profit-maximizing decision by a producer and the utility-maximizing decision by a consumer.
