INFLATIONARY EXPECTATIONS, AGGREGATE EXPENDITURES DETERMINANT: One of several specific aggregate expenditures determinants assumed constant when the aggregate expenditures line is constructed, and that shifts the aggregate expenditures line when it changes. An increase in inflationary expectations causes an increase (upward shift) of the aggregate expenditures line. A decrease in inflationary expectations causes a decrease (downward shift) of the aggregate expenditures line. Other notable aggregate expenditures determinants include interest rates, federal deficit, consumer confidence, and exchange rates.

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.

[What's This?]
Today, you are likely to spend a great deal of time flipping through mail order catalogs hoping to buy either an AC adapter for your CD player or storage boxes for your family photos. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
