DEBIT CARD: An increasing popular means of accessing the funds in a bank checking account. While debit cards look (and taste) almost exactly like credit cards, they are fundamentally different in how they are processed on a bank's end of the transaction. A credit card works through a liability (a loan with the bank). A debit card works through an asset (a checkable deposit with the bank). As such, debit cards are better suited for the title "plastic money" than credit cards.

DEMAND ELASTICITY AND TOTAL EXPENDITURE: The notion that price-induced changes in total expenditure for a good (price times quantity) depends on the relative price elasticity of demand. In particular, for relatively elastic demand (1 < E < ∞) changes in price cause total expenditure to change in the opposite direction. An increase in price causes total expenditure to fall and a decrease in price causes total expenditure to rise. For relatively inelastic demand (0 < E < 1) changes in price cause total expenditure to change in the same direction. An increase in price causes total expenditure to rise and a decrease in price causes total expenditure to fall. For unit elastic demand (E =1) price changes do not cause any change in total expenditure. Total expenditure is the same whether price increases or decreases.

PHYSICAL WEALTH, 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. A decrease in physical wealth causes an increase (upward shift) of the aggregate expenditures line. An increase in physical wealth causes a decrease (downward shift) of the aggregate expenditures line. Other notable aggregate expenditures determinants include consumer confidence, federal deficit, inflationary expectations, and exchange rates.
