Document Summary

Monopolies arise b/c of barriers to entry: a single firm owns a key resource that no other firm can access or has a close substitute for, 2. The government gives one firm the exclusive right to produce and sell some good. Its demand curve is the market demand curve. So, the monopoly faces a downward sloping demand curve. So if the firm wants to increase the q sold, it has to lower its p. Therefore, it gets less revenue for each additional good it sells. So: mr is always lower than p, the profit-maximizing monopolist will always choose to produce a level of output q such that, mr = mc < p, profit = tr tc. Monopoly = (monopoly price atc)*profit-maximizing quantity. Consumers lose surplus, the monopoly appropriates some surplus from consumers and some surplus no one gets (the dwl).

Select the correct answer:

A (legal; natural) monopoly exists when one firm can meet the entire market demand at a lower average total cost than two or more firms could.

A monopoly that is able to sell different units of a good or service for different prices is a (natural-price; price-discriminating) monopoly.

The act of obtaining special treatment by the government to create an economic profit is called (government surplus; rent seeking).

Regulated firms have an incentive to inflate their costs under (rate of return; price cap) regulation.

The U.S. Postal Service has a (natural; legal) monopoly on first class mail delivery.

A (single-price; price discriminating) monopoly maximizes profit by producing the quantity at which marginal revenue equals marginal cost and then charging the maximum price that consumers are willing to pay for that quantity.

The key idea behind price discrimination is to convert (consumer surplus; producer surplus) into economic profit.

In which of the following ways is a monopoly beneficial to an economy?

A. Monopoly profits give firms more reason to invest in the creation of new products through research and development.

B. Firms that are allowed monopoly profits search out innovative technologies that they can bring to market.

C. With natural monopolies, costs may be lower than those that would exist in competitive markets with many producers.

D. All of the above.

Which of the following is a difference between a perfectly competitive market and a monopoly?

B. The equilibrium price in a perfectly competitive market exceeds marginal revenue, while the equilibrium price in a monopoly equals marginal revenue.

C. The sellers in a perfectly competitive market are price-makers, while a seller in a monopoly market is a price-taker.

D. There are huge barriers to entry in a perfectly competitive market, while there are no barriers to entry in a monopoly.

In the United States in 2011, there were 104 fatalities per 100,000 workers in the logging industry. This is the second-highest rate after the fisheries industry. Although the fatality rate in this industry is so high, many workers still choose to work as loggers.

What could explain this?

A. Workers choose these high-risk jobs because they are willing to bear an occupational risk to earn a higher wage.

B. Low-risk jobs are already taken, so workers must choose their next-best alternative, which in this case is logging.

C. Workers in these industries lack human capital and must choose to work as loggers.

D. Loggers must be indifferent between low-risk and high-risk jobs.

In the case of a decrease in product prices:

A. the quantity effect always dominates the price effect.

B. the price effect always dominates the quantity effect.

C. when the price effect dominates the quantity effect, total revenue decreases.

D. when the quantity effect dominates the price effect, total revenue decreases
