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.

RESOURCE QUANTITY, AGGREGATE SUPPLY DETERMINANT One of three categories of aggregate supply determinants assumed constant when the short-run and long-run aggregate supply curves are constructed, and which shifts both aggregate supply curves when it changes. An increase in a resource quantity causes an increase (rightward shift) of both aggregate supply curves. A decrease in a resource quantity causes a decrease (leftward shift) of both aggregate supply curves. The other two categories of aggregate supply determinants are resource quality and resource price. Specific determinants falling into this general category include population, labor force participation, capital stock, and exploration. Anything affecting the quantity of labor, capital, land, and entrepreneurship is also included.
