Chapter 3—Demand Analysis
MULTIPLE CHOICE
1. Suppose we estimate that the demand elasticity for fine leather jackets is ‑.7 at their current prices. Then we know that:
a. a 1% increase in price reduces quantity sold by .7%.
b. no one wants to buy leather jackets.
c. demand for leather jackets is elastic.
d. a cut in the prices will increase total revenue.
e. leather jackets are luxury items.
ANS: A PTS: 1
2. If demand were inelastic, then we should immediately:
a. cut the price.
b. keep the price where it is.
c. go to the Nobel Prize Committee to show we were the first to find an upward-sloping demand curve.
d. stop selling it since it is inelastic.
e. raise the price.
ANS: E PTS: 1
3. In this problem, demonstrate your knowledge of percentage rates of change of an entire demand function (Hint: %ΔQ = EP•%ΔP + EY•%ΔY). You have found that the price elasticity of motor control devices at Allen-Bradley Corporation is -2, and that the income elasticity is a +1.5. You have been asked to predict sales of these devices for one year into the future. Economists from the Conference Board predict that income will be rising 3% over the next year, and AB’s management is planning to raise prices 2%. You expect that the number of AB motor control devices sold in one year will:
fall .5%.
not change.
rise 1%r.
rise 2%.
rise .5%.
ANS:EPTS: 1
4 A linear demand for lakefront cabins on a nearby lake is estimated to be: QD = 900,000 – 2P. What is the point price elasticity for lakefront cabins at a price of P = $300,000? [Hint: Ep = (Q/P)(P/Q)]
EP = -3.0
EP = -2.0
EP = -1.0
EP = -0.5
EP = 0
ANS: B PTS: 1
5. Property taxes are the product of the tax rate (T) and the assessed value (V). The total property tax collected in your city (P) is: P = T•V. If the value of properties rise 4% and if Mayor and City Council reduces the property the tax rate by 2%, what happens to the total amount of property tax collected? [hint: the percentage rate of change of a product is approximately the sum of the percentage rates of change.}
a. It rises 6 %.
b. It rises 4 %.
c. It rises 3 %.
d. It rises 2 %
e. If falls 2%.
ANS: D PTS: 1
6. Demand is given by QD = 620 ‑ 10·P and supply is given by QS = 100 + 3·P. What is the price and quantity when the market is in equilibrium?
a. The price will be $30 and the quantity will be 132 units.
b. The price will be $11 and the quantity will be 122 units.
c. The price will be $40 and the quantity will be 220 units.
d. The price will be $35 and the quantity will be 137 units
e. The price will be $10 and the quantity will be 420 units.
ANS: C PTS: 1
7. Which of the following would tend to make demand INELASTIC?
-
- a. the amount of time analyzed is quite long
- b. there are lots of substitutes available
- c. the product is highly durable
- d. the proportion of the budget spent on the item is very small
- e. no one really wants the product at all
ANS: D PTS: 1
8. Which of the following best represents management’s objective(s) in utilizing demand analysis?
a.
it provides insights necessary for the effective manipulation of demand
b.
it helps to measure the efficiency of the use of company resources
c.
it aids in the forecasting of sales and revenues
d.
a and b
e.
a and c
ANS: E PTS: 1
9. Identify the reasons why the quantity demanded of a product increases as the price of that product decreases.
a.
as the price declines, the real income of the consumer increases
b.
as the price of product A declines, it makes it more attractive than product B
c.
as the price declines, the consumer will always demand more on each successive price reduction
d.
a and b
e.
a and c
ANS: D PTS: 1
10. An increase in the quantity demanded could be caused by:
a.
an increase in the price of substitute goods
b.
a decrease in the price of complementary goods
c.
an increase in consumer income levels
d.
all of the above
e.
none of the above
ANS: D PTS: 1
