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.

DISCOUNT RATE The interest rate charged by the Federal Reserve System (the Fed) for loans to commercial banks, which in principle can be used as a means of a controlling the money supply. An increase in the money supply can be achieved when the Fed lowers the discount rate. A decrease in the money supply can be achieved when the Fed raises the discount rate. The discount rate, which is set by Federal Reserve Banks, subject to approval by the Board of Governors, is used more to signal changes in monetary policy rather than to actually control the money supply. The discount rate is one of the three monetary policy tools that the Fed can use, in principle, to control the money supply. The other two are open market operations and reserve requirements.
