There is not enough information to answer the question.

The monopolist's marginal revenue curve is

downward sloping and lies below the firm's demand curve.

The market demand curve in a perfectly competitive market is

downward sloping.

In the long run, new firms will enter a monopolistic competitive industry until

economic profits in the industry are zero.

A natural monopoly exists when

economies of scale are so large that only one firm can survive and achieve low unit costs.

The theory of contestable markets concludes that

even if the number of sellers in an industry is small, profits can be zero in the industry.

Compared to a monopolistic competitor, a monopolist produces a good with __________ substitutes and so has a __________ elastic demand curve.

fewer; less

The Justice Department considers a Herfindahl index ____________________________ to be representative of a concentrated industry.

greater than 1,800

For a single-price monopoly, marginal revenue is

less than price for all units of output after the first unit.

less; less

The profit-maximizing perfectly competitive firm charges a price equal to __________ while the profit-maximizing monopolistic competitive firm charges a price __________.

marginal cost; greater than marginal cost

A monopolistic competitive firm maximizes profits by producing at the point where

marginal revenue equals marginal cost.

The profit-maximizing monopolistic competitive firm produces the level of output at which

marginal revenue equals marginal cost.

The profit-maximizing oligopolist produces at the level of output where

marginal revenue equals marginal cost.

When a perfectly competitive firm incurs losses, it follows that price

must be below average total cost.

q2CAq1

The capture theory of regulation holds that

regardless of the motive for the initial regulation and the establishment of the regulatory agency, eventually the regulatory agency will be "captured" (controlled) by the special interests of the industry that is being regulated.

The public interest theory of regulation holds that

regulators are seeking to do and will do through regulation what is in the best interest of the public.

A firm produces the quantity of output at which P = MC and P = ATC. It follows that the firm is

resource allocative efficient, but not necessarily productive efficient.

"Rent seeking" is socially wasteful because

resources devoted to transferring rents are not used to produce goods.

In the past, it was theorized that __________ firms were the most likely to innovate. In recent years, new information has suggested that __________ firms are greater innovators. If true, this makes antitrust intervention in the case of mergers __________ important.

stock market.

Which antitrust legislation made price discrimination illegal?

the Clayton Act

The antitrust legislation that declares illegal "unfair methods of competition in commerce" is

the Federal Trade Commission Act.

Marginal revenue is

the change in total revenue brought about by selling an additional unit of the good.

Large firms may be more likely to innovate because

the risks of failure are less to them than to small firms

The demand curve facing a monopolist is always

the same as the industry demand curve.

If a market comes close to meeting (but does not perfectly meet) all the assumptions of the theory of perfect competition, it follows that

the theory of perfect competition still may be able to predict behavior in the market.

A local government prevents any firm from competing with a natural monopoly firm. Those people who believe this is a wise policy action would likely say

this is a desirable state of affairs since if competition is allowed, the natural monopoly firm will out compete all newcomers and in the end the newcomers will go out of business.

According to the textbook, in recent years which of the following industries has had high four- and eight-firm concentration ratios?

A price searcher is

a seller that can sell some of its output at various prices

adding the squares of the market shares of each firm in the industry.
