d. average total cost is equal to marginal revenue.

Question 3

a. one firm is the only supplier of a product for which there are no close substitutes
b. entry into the market is blocked
c. the firm can influence market price

c. always charges a price that is higher than marginal revenue.
d. both b and c

Question 5

b. Low cross-price elasticity with other products

d. all of the above

Question 6
The table shows a monopolist s demand schedule:

Price Quantity

$50 300
40 600
20 800
10 1,000

What is the marginal revenue for a price decrease from $50 to $40?
a. $9,000
b. $24,000
c. $30
d. $20

Question 7
The following table shows a monopolist s demand schedule:
Price Quantity
$50 300
40 600
20 800
10 1,000

If price falls from $20 to $10, then

a. MR = -$10, and demand is inelastic.
b. MR = $10, and demand is elastic.
c. MR = $30, and demand is elastic.
d. MR = -$30, and demand is inelastic.

Question 8
A monopolist will maximize profit by producing the level of output at which
a. the firm's total revenue exceeds total cost by the largest amount.
b. marginal revenue equals marginal cost.
c. the last unit of output produced adds the same amount to total revenue as to total cost.
d. all of the above

Question 9

A monopoly is producing a level of output at which price is $80, marginal revenue is $40, average total cost is $100, marginal cost is $40, and average fixed cost is $10. In order to maximize profit, the firm should
a. produce more.
b. keep output the same.
c. produce less.
d. Shut down

Question 10
A firm facing a downward sloping demand curve is producing a level of output at which price is
$7, marginal revenue is $5, and average total cost, which is at its minimum value, is $3. In order
to maximize profit, the firm should
a. decrease price.
b. keep price the same.
c. decrease output.
d. increase price.

Question 11
A monopolist is currently hiring 5,000 units of labor. At this level, the marginal revenue of
output is $10, the (fixed) wage rate is $300, and the marginal product of labor is 50. In order to
maximize profit, the firm should
a. keep the level of employment the same because the firm is earning a profit of $100,000.
b. hire more labor because the next unit of labor increases profit by $500.
c. hire more labor because the next unit of labor increases profit by $200.
d. hire less labor because the last unit of labor added more to total cost ($300) than to total revenue ($10).

Question 12
A firm with market power will maximize profit by hiring the amount of an input at which the
a. last unit of the input hired adds the same amount to total revenue as to total cost
b. additional revenue from the last unit of the input hired exceeds the additional cost of the last unit by the largest amount.
c.last unit of the input hired adds the same amount to total output as to total cost.
d. additional output from the last unit of the input hired exceeds the additional cost of the last unit by the largest amount.

Question 13
A monopolistically competitive firm chooses
a. price, but output is determined by cartel production quota.
b. the quantity of output to produce and the price at which it will sell its output.
c. the quantity of output to produce, but the market determines price.
d. the price, but competition in the market determines the quantity.

Question 14
Characteristics shared by monopolistically competitive and monopoly markets alike include
a. strategic interactions among sellers.
b. many sellers.
c. firms facing a downward-sloping demand curve.
d. insignificant barriers to entry.

Question 15
When free entry is one of the attributes of a market structure, economic profits are
a. eventually eventually driven to zero.
b. negative for all firms.
c. never above or below zero
d. always positive.
