And their profits will be

$0

What are the profits for Dumphy and Funke at the equilibrium price?

$0

Iz, Lauren, Odd, and Ralph started a T‑shirt company. They can produce any number of T‑shirts at a cost of $2 per T‑shirt, both marginal and average. They are the only producers of T‑shirts. As monopolists, they charge $20 per T‑shirt and obtain total profits of $10,000. Now assume there are creative differences and they split the company in two. Lauren and Ralph join together and compete against Iz and Odd. If they compete on quantity, each company would produce 50 T‑shirts and charge $12 a T‑shirt. For technical reasons, assume that the quantity demanded is greater than zero for all prices greater than $0. If, however, Ralph and Lauren compete directly against Iz and Odd in prices, the market price for T‑shirts will be

$2

Suppose you are a manager of a firm that operates in a duopoly. Recently, the state attorney general fined you and your competitor for price fixing. In your market, firms only set prices, not total quantities to sell. From previous experience, you know your competitor has a marginal cost of $2.76. Further, your marginal costs are $2.74. The previous cartel price was $10.00, when you and your competitor were price fixing. What price level do you now choose to maximize profits?

$2.75

What will be the equilibrium price that Dumphy and Funke will charge?

$30

Technology Superiority

A firm that maintains a consistent technological advantage over potential competitors can establish itself as a monopolist. For example, from the 1970s through the 1990s the chip manufacturer Intel was able to maintain a consistent advantage over potential competitors in both the design and production of microprocessors, the chips that run computers.

Control of a scarce resource or input

A monopolist that controls a resource or input crucial to an industry can prevent other firms from entering its market. Cecil Rhodes created the De Beers monopoly by establishing control over the mines that produced the great bulk of the world's diamonds.

Identify the first antitrust law and its purpose.

The Sherman Act of 1890 prohibits price fixing, collusion, and monopolization.

The Environmental Protection Agency is attempting to rule on whether pollution from greenhouse gas emissions endangers public safety. Among the many greenhouse gas polluters are cows emitting methane. Economists have devised a theory to help address this issue. Identify the statement that is true according to economic theory.

The efficient level of pollution removal occurs where the marginal benefit of pollution removal equals the marginal cost of pollution removal; i.e., some pollution could be allowed.
