B)Decreasing average cost
C)A low cost method of production known only by monopolists
D)Increasing returns to scale

Question 11

If the government requires a natural monopoly to price at marginal cost:

A)monopoly firms will earn zero economic profits because the price of the good equals the cost of producing that good.
B)monopoly firms will operate at a loss because P < AC.
C)more firms will be able to enter the market.

C)have similar costs among markets.
D)have a downward sloping marginal cost curve.

Question 13

Relative to uniform-price policy,price discrimination across segmented markets (sometimes called third-degree price discrimination):

A)always reduces welfare.
B)always increases welfare.
C)may increase welfare if total output falls.
D)may increase welfare if total output rises.

Question 14

refer to a monopoly that faces a demand curve given by and has a constant marginal cost as 0.2.
In this situation the monopoly's profit maximizing output level is:

A)0.2.
B)0.4.
C)0.5.
D)0.7.

Question 15

All of the following might explain a firm offering quantity discounts except:

A)the lower costs of handling large orders.
B)an inelastic demand for the good.
C)a monopoly power in this market.
D)the adoption of a sales maximization strategy.

Question 16

One possible benefit of a monopoly is:

A)a more efficient allocation of resources;only one firm is needed to supply quantity demanded.
B)greater incentives for research due to long-run positive economic profits.
C)the government is better able to ensure that it follows laws and guidelines because there is only one firm to monitor.
D)goods and services are provided at a lower price than under perfect competition because of a monopoly's decreasing average cost curve.

Question 17

The principal difference between economic profits for a monopolist and for a competitive firm is that:

A)monopoly profits create major problems of equity whereas competitive profits do not.
B)competitive profits exist only in the short run whereas monopoly profits may exist in the long run as well.
C)monopoly profits represent a transfer out of consumer surplus whereas competitive profits do not.
D)monopoly profits are usually larger than competitive profits.

Question 18

If a monopoly is maximizing profits:

A)price will always be greater than average cost.
B)price will always equal marginal cost.
C)price will always be greater than marginal cost.
D)price will always equal marginal revenue.

Question 19

A monopoly's economic profits are represented by:

A)(price minus marginal cost)times number of units sold.
B)(price minus average cost)times number of units sold.
C)(marginal revenue minus price)times number of units sold.
D)(marginal cost minus price)times number of units sold.

Question 20

The supply curve for a monopoly is given by:

A)the firm's marginal cost curve above the average variable cost curve.
B)the one point on the demand curve that corresponds to the quantity for which price is equal to MC.
C)the one point on the demand curve that corresponds to the quantity for which MR equals MC.
D)the entire demand curve above the point where price is equal to average cost.

Question 21

A monopolist has marginal revenue And marginal cost ,where Is some factor shifting marginal costs up.Applying comparative-static analysis to the profit-maximization condition What can be learned about the effect of
On monopoly output,or in mathematical terms,what can be learned about the derivative ?
I.
​II.
​III. ,if the monopolist's profit function is concave.
IV. ,if the monopolist's profit function is concave.

A)​I and III
B)​II and III
C)​I and IV
D)​II and IV

Question 22

​How does monopoly product quality compare to the quality a social planner would choose?

A)​The monopolist targets the marginal consumer's valuation of quality,whereas the social planner targets the average consumer's.This leads the monopolist to make inefficiently low-quality products.
B)​The monopolist targets the marginal consumer's valuation of quality,whereas the social planner targets the average consumer's.This leads the monopolist to make inefficiently high-quality products.
C)​There is no difference due to a standard neutrality argument.
D)​None of the above.
