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.

ARC ELASTICITY The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.
