generally fails to maximize total economic well being

illegal

There are two types of markets in which firms face some competition yet are still able to have some control over the prices of their products. Those two types of market are
monopolistic competition and oligopoly.
Under which of the following market structures would consumers likely pay the highest price for a product?
monopoly
Oligopolies would like to act like a
monopoly, but self-interest often drives them closer to the perfectly competitive outcome.

movies
Refer to Figure 15-1. The shape of the average total cost curve reveals information about the nature of the barrier to entry that might exist in a monopoly market. Which of the following monopoly types best coincides with the figure?
natural monopoly
Because the goods offered for sale in a competitive market are largely the same,
sellers will have little reason to charge less than the going market price.
The short-run market supply curve in a perfectly competitive industry
shows the total quantity supplied by all firms at each possible price.
If a pharmaceutical company discovers a new drug and successfully patents it, patent law gives the firm

Which of the following statements is correct?
Game theory is not necessary for understanding competitive or monopoly markets.

break up companies
Refer to Figure 15-4. If the monopoly firm is currently producing Q3 units of output, then a decrease in output will necessarily cause profit to
decrease

rarely possible
When entry and exit behavior of firms in an industry does not affect a firm's cost structure,
the long-run market supply curve must be horizontal.
In a perfectly competitive market, the horizontal sum of all the individual firms' supply curves is
the market supply curve
The assumption of a fixed number of firms is appropriate for analysis of
the short run but not the long run.
Most markets are not monopolies in the real world because
there are reasonable substitutes for most goods.
Which of the following is correct? When oligopolies collude
they make higher profits but consumers of the product are worse off.
Refer to Table 15-4. In order to maximize profits, the monopolist should produce
where marginal revenue equals marginal cost.
When the marginal revenue curve is drawn for a monopolist, the curve
is below the monopolist's demand curve, beyond the initial unit produced.

P2-P5.
Refer to Figure 15-3. Which of the following statements is correct?
Panel B represents the typical demand curve for a perfectly competitive firm, and Panel A represents the typical demand curve for a monopoly.
When we compare economic welfare in a monopoly market to a competitive market, the profits earned by the monopolist represent
a transfer of benefits from the consumer to the producer.
Refer to Figure 17-2. If this game is played only once, then the most likely outcome is that
both firms produce a good quality product.
The entry of new firms into a monopolistically competitive market is accompanied by
both positive and negative externalities.
The textile industry is composed of a large number of small firms. In recent years, these firms have suffered economic losses, and many sellers have left the industry. Economic theory suggests that these conditions will
cause the market supply to decline and the price of textiles to rise.
Monopolies use their market power to
charge a price that is higher than marginal cost
Refer to Table 14-7. If the firm is currently producing 14 units, what would you advise the owners?
continue to operate at 14 units
A distinguishing feature of an oligopolistic industry is the tension between
cooperation and self interest.
In a natural monopoly,
if the government requires marginal cost pricing, it will likely have to subsidize the firm.
A competitive firm is currently producing a quantity of output at which marginal revenue exceeds marginal cost. In order to increase its profit, the firm should
increase its quantity of output.
A restaurant that has market power can
influence the market price for the meals it sells
Refer to Figure 14-6. Firms will be earn losses in the short run but will remain in business if the market price
is greater than P1 but less than P3.
A movie theater can increase its profits through price discrimination by charging a higher price to adults and a lower price to children if
it has some degree of monopoly-pricing power.
A monopoly is an inefficient way to produce a product because
it produces a smaller level of output than would be produced in a competitive market.
Refer to Figure 14-4. When price falls from P3 to P1, the firm finds that it
should shut down immediately

Which of the following is not correct?
A monopolist can charge any price and sell any quantity that it chooses.
Predatory pricing occurs when
A monopolist decreases its prices to maintain its monopoly. Economists are skeptical that this practice is profitable.

all of the above
The equilibrium price in a market characterized by oligopoly is
lower than in monopoly markets and higher than in perfectly competitive markets.
Profit-maximizing firms in a competitive market produce an output level where
marginal cost equals marginal revenue.
Kate is a professional opera singer who gives voice lessons. The vocal-music industry is competitive. Kate hires a business consultant to analyze her financial records. The consultant recommends that Kate give fewer voice lessons. The consultant must have concluded that Kate's
marginal cost exceeds her marginal revenue.
In a perfectly competitive market, the process of entry and exit will end when firms face
marginal revenue equal to long-run average total cost.
A profit-maximizing monopolist will produce the level of output at which
marginal revenue is equal to marginal cost.
Refer to Figure 14-1. If the market price is $5.00, the firm will earn
negative economic profits in the short run but remain in business.
Refer to Figure 16-9. Given this firm's cost curves, if the firm were perfectly competitive rather than monopolistically competitive, then in a long-run equilibrium it would produce
not between 100 and 133

not up right
Game theory is important for understanding which of the following market types?
oligoplistic but not perfectly competitive markets
Antitrust laws in general are used to
prevent oligopolists from acting in ways that make markets less competitive.
In a long-run equilibrium, the marginal firm has
price equal to average total cost total revenue equal to total cost economic profit equal to zero
For a long while, electricity producers were thought to be a classic example of a natural monopoly. People held this view because
the average cost of producing units of electricity by one producer in a specific region was lower than if the same quantity were produced by two or more producers in the same region.
If a monopolistically competitive firm can increase its level of production and lower its average total cost of production at the same time then
the firm has excess capacity.
