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.

ECONOMICS A social science that studies the allocation of limited resources used to produce the goods and services that satisfy unlimited consumer wants and needs. Economics is one of several social sciences (others are sociology, political science, and anthropology) which applies the scientific method to human behavior. The distinguishing feature of economics is a concern with the fundamental problem of scarcity--unlimited wants and needs and limited resources. Economics is commonly divided into two branches--macroeconomics and microeconomics.
