QUANTITY THEORY OF MONEY: A theory that states a given percentage change in the money supply leads to an equal percentage change in nominal gross domestic product. This theory is derived from the equation of exchange and is a cornerstone of the monetarists view of macroeconomics. A key assumption in translating the equation of exchange to the quantity theory of money is that the velocity of money is constant (or unaffected by the other key variables--output, price level, and money supply).

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.

MARGINAL FACTOR COST, PERFECT COMPETITION The change in total factor cost resulting from a change in the quantity of factor input employed by a perfectly competitive firm. Marginal factor cost, abbreviated MFC, indicates how total factor cost changes with the employment of one more input. It is found by dividing the change in total factor cost by the change in the quantity of input used. Marginal factor cost is compared with marginal revenue product to identify the profit-maximizing quantity of input to hire.

[What's This?]
Today, you are likely to spend a great deal of time looking for a downtown retail store hoping to buy either a half-dozen helium filled balloons or a packet of address labels large enough for addresses of both the sender and the recipient. Be on the lookout for defective microphones.
