B) inelastic.

C) perfectly inelastic.

D) unit-elastic.

32) For consumers who opt to pay a $10 monthly fee to have unlimited texting on their cell phones, but choose not to pay a $5 monthly fee to have unlimited call minutes, the unlimited texting option has a ________ than the unlimited minutes option.

A) higher price elasticity of demand

B) higher cross-price elasticity of demand

C) lower price elasticity of demand

33) Economists use the concept of ________ to measure how one economic variable, such as quantity, responds to a change in another economic variable, such as price.

A) slope

B) efficiency

C) relativity

D) elasticity

34) The price elasticity of demand is equal to

A) the value of the slope of the demand curve.

B) the change in quantity demanded divided by the change in price.

C) the percentage change in price divided by the percentage change in quantity demanded.

D) the percentage change in quantity demanded divided by the percentage change in price.

35) To calculate the price elasticity of demand we divide

A) the percentage change in quantity demanded by the percentage change in price.

B) the percentage change in price by the percentage change in quantity demanded.

C) rise by the run.

D) the average price by the average quantity demanded.

36) The slope of a demand curve is not used to measure the price elasticity of demand because

A) the slope of a linear demand curve is not constant.

B) the slope of a line cannot have a negative value.

C) the measurement of slope is sensitive to the units chosen for price and quantity.

D) the slope of the demand curve does not tell us how much quantity changes as price changes.

37) If the slope of a demand curve is equal to -0.1 then

A) demand is inelastic.

B) we don’t know whether the demand is elastic or inelastic.

C) the demand is elastic at low prices and inelastic at high prices.

D) as price increases by 10 percent quantity demanded decreases by 1 percent.

38) The price elasticity of demand for beef is estimated to be 0.60 (in absolute value). This means that a 20 percent increase in the price of beef, holding every thing else constant, will cause the quantity of beef demanded to

A) decrease by 12 percent.

B) decrease by 26 percent.

C) decrease by 32 percent.

D) decrease by 60 percent.

A) aspirin is a normal good.

B) the demand for aspirin is inelastic.

C) aspirin has few substitutes.

D) the demand for aspirin is elastic.

40) If demand is perfectly elastic, the absolute value of the price elasticity coefficient is

A) infinity.

B) zero.

C) more than one.

D) equal to the absolute value of the slope of the demand curve.
