All of the answers above are correct.
C
A monopolist earns an economic profit only when: a. average total cost equals price. b. marginal cost equals price. c. marginal revenue equals price. d.average total cost is less than price.

D
A monopoly: a. faces the market demand curve which is downward sloping. b. has a marginal revenue curve which slopes downward and lies below its demand curve. c. will maximize profits by producing an output level where MR = MC. d. All of the answers above are correct.
D
CH. 9, EX. 1 In Exhibit 1, the monopolist would charge which of the following prices to maximize profit or minimize its loss? a. $20. b. $40. c. $60. d. $70. e. $100.
D
Suppose a monopolist's demand curve lies below its average variable cost curve. The firm will: a. stay in operation in the short‑run. b. earn an economic profit. c. earn an economic profit in the long run. d. shut down
D
Which of the following is true for the monopolist? a. Marginal revenue is less than the price charged. b. Economic profit is possible in the long run. c. Profit maximizing or loss minimizing occurs when marginal revenue equals marginal cost. d.All of the answers above are correct.
D
_________ is the act of buying a commodity in one market at a lower price and selling it in another market at a higher price. a. Buying short. b. Discounting. c. Tariffing. d. Arbitrage.
D
Under both perfect competition and monopoly, a firm: a. is a price taker. b. is a price maker. c. will shut down in the short-run if price falls short of average total cost. d. always earns a pure economic profit. e. sets marginal cost equal to marginal revenue.
E
A monopolist that maximizes total revenue earns maximum economic profit
F
A natural monopoly maximizes profits at the point at which price equals minimum average total cost.
F
For a monopoly, price always equals marginal revenue
F
Regardless of the demand for its product, a monopolist will be able to earn positive economic profits.
F
To earn an economic profit in the short‑run, a monopolist sets marginal revenue equal to zero.
F
A monopolist is a price searcher because it has the ability to select the price along its demand curve of its product.
T
An argument in favor of price discrimination is that this pricing strategy permits some consumers who otherwise would be excluded from a market to buy a good or service
T
Costs in a natural monopoly are lower because there is only one producer.
T
In order for a monopolist to earn a pure economic profit in short‑run equilibrium, price must exceed average total cost.
T
___________________ is a single seller facing the entire industry demand curve. The reason for this type of market structure is that the firm sells a unique product and extremely high barriers to entry protect it from competition. These barriers to entry include: (1) ownership of an essential resource, (2) legal barriers, and (3) economies of scale.
monopoly
A (an) __________________________ arises because of the existence of economies of scale in which the LRAC falls as production increases. As a result, smaller firms leave the industry, new firms fear competing with the monopolist, and the result is that a monopoly emerges naturally.
natural monopoly
_________________________ allows the monopolist to increase profits by charging buyers different prices rather than a single price. There are three necessary conditions for this condition to exist: (1) the demand curve must be downward sloping, (2) buyers in different markets must have different demand curves, and (3) the buyer must be able to prevent ___________________which is reselling the product at a higher price than the purchase price.
price discrimination, arbitrage
A firm that faces a downward‑sloping demand curve is called a (an) ________________________.
price maker
