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).

Aggregate Shocks
In this lesson we use the aggregate market model to analyze assorted disruptions that cause shifts of the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves. The reason for doing this, of course, is to explain and understand macroeconomic activity, especially business cycle instability that causes inflation and unemployment. - The first unit of this lesson reviews the aggregate market and examines how it is affected macroeconomic instability.
- In the second unit, we take and look at assorted demands on both the demand side and supply side of the aggregate market that cause shorts to the aggregate market.
- We then move into an analysis of six basic shifts involving increases and decreases in the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves.
- The fourth unit builds on these six basic shifts to examine four complex shifts in which recessionary and inflationary gaps trigger self-correction adjustments of the short-run aggregate supply.
- We close out this lesson in the fifth with a thought or two on how the aggregate market can be used to explain business cycle fluctuations.

MARGINAL REVENUE, MONOPOLY The change in total revenue resulting from a change in the quantity of output sold. Marginal revenue indicates how much extra revenue a monopoly receives for selling an extra unit of output. It is found by dividing the change in total revenue by the change in the quantity of output. Marginal revenue is the slope of the total revenue curve and is one of two revenue concepts derived from total revenue. The other is average revenue. To maximize profit, a monopoly equates marginal revenue and marginal cost.
