  3. C
  4. D
  5. E
Question 7 (1 point)
Suppose the price of a product is reduced from $10 to $6 and the quantity demanded increases from 40 to 60 units. From this we can conclude that the price elasticity of demand over this price range is equal to

  3. 1.25.
  4. 0.20.
  5. Cannot be determined from the information given.
Question 8 (1 point)
If a liquor store owner decides that raising the price of beer can pay for the construction of a new building, then the owner is assuming that the
  1. percentage increase in the price of beer will cause an equal percentage decrease in the quantity demanded.
  2. percentage increase in the price of beer will cause a smaller percentage decrease in the quantity demanded.
  3. demand for his or her beer is elastic.
  4. demand for his or her beer is unit-elastic.
  5. percentage increase in the price of beer will cause a greater percentage decrease in the quantity demanded.
Question 9 (1 point)
In the figure above, the section of the demand curve from D to F is
  1. the inelastic range of the demand curve.
  2. the elastic range of the demand curve.
  3. the unit-elastic part of the demand curve.
  4. the perfectly inelastic range of the demand curve.
  5. the perfectly elastic range of the demand curve.
Question 10 (1 point)
Which of the following is an example of price discrimination?
  1. Senior citizen discounts
  2. Discount airline fares for leisure travelers
  3. Grocery coupons
  4. "Kids stay free" signs at chain hotels
  5. All of these.
Question 11 (1 point)
In general, price-discriminating firms should charge higher prices to those customers
  1. with a lower income elasticity of demand.
  2. with more elastic demand.
  3. who are taller.
  4. with more inelastic demand.
  5. with unitary elasticity of demand.
Question 12 (1 point)
Which of the following is not a determinant of the price elasticity of demand?
  1. The prices of resources available to the producer of the good
  2. The number of substitutes available for the product
  3. The importance of the product in the consumer's total budget
  4. The amount of time available to the consumer
  5. None of these.
Question 13 (1 point)
If there are few substitutes for a product, few competitors, and a short time period under consideration, then
  1. the price elasticity of demand coefficient is equal to 1.
  2. this product has a demand that is price elastic.
  3. a given percentage change in price will result in a much larger percentage change in the quantity demanded.
  4. the price elasticity of demand is large.
  5. if price rises, total revenue (or total consumer expenditures) will also rise.
Question 14 (1 point)
Which of the following is true with respect to the price elasticity of demand?
  1. A coefficient of 1 means that the percentage change in total expenditure is equivalent to the percentage change in price.
  2. Elasticity will tend to be greater for a relatively expensive product than for a cheaper one.
  3. Elasticity measures the sensitivity of total expenditure to a change in price.
  4. Elasticity of demand can be measured by the slope of the demand curve.
  5. The coefficient will change with changes in the units of measurement (for instance, going from pounds to ounces).
Question 15 (1 point)
During the spring of 2003, the price of gasoline increased, and it became more expensive to drive sport utility vehicles (SUVs). What is a likely effect of a significant, long-term increase in the price of gasoline?

  5. None of these.
Question 16 (1 point)
Cross-price elasticity is defined by
  1. the change in quantity demanded divided by the change in income.

Question 17 (1 point)
