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.

UNEMPLOYMENT RATE, MEASUREMENT PROBLEMS The official unemployment rate, which measures the proportion of the civilian labor force 16 years or older that is not engaged in productive activities but is actively seeking employment, might be either overstated or understated due to discouraged workers, part-time workers, and unreported legal or illegal employment. Taken together, these measurement problems suggest that the official unemployment rate is likely understated during business-cycle contraction and overstated during business-cycle expansions.
