Macroeconomic Uses of Demand and Supply
Demand and supply have also been generalized to explain macroeconomic variables in a market economy, including the quantity of total output and the general price level. The Aggregate Demand-Aggregate Supply model may be the most direct application of supply and demand to macroeconomics, but other macroeconomic models also use supply and demand. Compared to microeconomic uses of demand and supply, different (and more controversial) theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. Demand and supply are also used in macroeconomic theory to relate money supply and money demand to interest rates, and to relate labor supply and labor demand to wage rates.

Famous quotes containing the words demand and/or supply:
“The laws of custom make our [returning a visit] necessary. O how I hate this vile custom which obliges us to make slaves of ourselves! to sell the most precious property we boast, our time;—and to sacrifice it to every prattling impertinent who chooses to demand it!”
—Frances Burney (1752–1840)
“Dear to us are those who love us ... but dearer are those who reject us as unworthy, for they add another life; they build a heaven before us whereof we had not dreamed, and thereby supply to us new powers out of the recesses of the spirit, and urge us to new and unattempted performances.”
—Ralph Waldo Emerson (1803–1882)
