When a monopolist increases the amount of output that it produces and sells, its average revenue
decreases and its marginal revenue decreases
Drug companies are allowed to be a monopolist in the drugs they discover in order to

Price discrimination explains why Ivy League universities often set rules that determine prices of admission based on students'
financial resources
Patent and copyright laws are major sources of

Inefficiency arises from a monopoly because
some buyers will refrain from buying the good, due to the high price

For a monopoly firm, the level of output at which marginal revenue equals zero is also the level of output at which
total revenue is maximized
Economic well-being is measured by
total surplus and the sum of consumer surplus and producer surplus
Antitrust laws allow the government to
-prevent mergers -break up companies -promote competition
Government-run monopolies may lead to undesirable outcomes in the form of
-special interest groups that attempt to block cost reductions -customers and taxpayer losses when the monopoly operates inefficiently -the political system as the only form of recourse for customers
When regulators use a marginal cost pricing strategy to regulate a natural monopoly, the regulated monopoly
-will experience a loss -will experience a price below average total cost -may rely on a government subsidy to remain in business
Competitive firms and monopolists differ in what way?
a competitive firm's marginal revenue curve is horizontal; a monopolist's marginal revenue curve is downward sloping

As a monopolist increases the quantity of output it sells, the price consumers are willing to pay for the good
decreases
Marginal revenue can become negative for
monopoly firms, but not for competitive firms
In view of what we know about the relationship between average total cost and marginal cost, the marginal cost curve for this firm
must lie entirely below the average total cost curve
When a firm experiences naturally declining average total costs, the firm is a
natural monopoly
For a monopolist, when does the marginal revenue exceed average revenue?
never
What is not a characteristic of a monopoly?

The deadweight loss associated with a monopoly occurs because the monopolist
