PHYSICAL WEALTH, AGGREGATE DEMAND DETERMINANT: One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in the physical wealth causes a decrease (leftward shift) of the aggregate curve. A decrease in the physical wealth causes an increase (rightward shift) of the aggregate curve. Other notable aggregate demand determinants include interest rates, federal deficit, inflationary expectations, and the money supply.

This market graph combines the forces of demand and supply.- Equilibrium is achieved as each side of the market seeks a mutually agreeable exchange.
- The equilibrium price is 50 cents and the equilibrium quantity is 400 tapes. At this 50-price, the quantity demanded is equal to the quantity supplied.
- At no other price is the quantity demanded and supplied equal.
- That's equilibrium.

MARKET FAILURES Imperfections in the exchange process between buyers and sellers that prevent markets from efficiently allocating scarce resources. Market failures come in four varieties -- public goods, market control, externalities, and imperfect information. Market efficiency is achieved if the value of goods produced is equal to the value of foregone production. Markets fail when this efficiency condition is not achieved. Such failures can only be corrected by government intervention.
