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.

BANK RUN A situation in which a relatively large number of a bank's customers attempt to withdraw their deposits in a relatively short period of time, usually within a day or two. While common throughout the 1800s and early 1900s, government deposit insurance has largely eliminated banks runs in the modern economy. Historically a bank run was prompted by fears that the bank was on the verge of collapse, causing deposits to become worthless. Ironically a bank run often caused the bank to fail. Bank runs were often infectious, leading to economy-wide bank panics and business-cycle contractions.
