Economics Ch.9
An industry is said to be a natural monopoly when:
long-run average cost continues to decline as the quantity of output increases.
Under both perfect competition and monopoly, a firm:
maximizes profit by setting marginal cost equal to marginal revenue.
Under monopoly, a firm:
maximizes profit by setting marginal cost equal to marginal revenue.
A monopoly:
must lower price in order to increase output.

One necessary condition for effective price discrimination is:
difference in the price elasticity of demand among buyers.
The goal of any monopolist is to maximize:
economic profits.
A monopoly:
faces the market demand curve which is downward sloping. has a marginal revenue curve which slopes downward and lies below its demand curve. will maximize profits by producing an output level where MR = MC.
If marginal costs increase, a monopolist will:
increase price and decrease output.
A monopoly sets a market price that is higher than the marginal cost of production. This fact implies that a monopoly's allocation of resources is:
inefficient.
Under both perfect competition and monopoly, a firm:
sets marginal cost equal to marginal revenue.
Monopoly is a market structure characterized by a:
single firm that is not a price taker.
The monopolist faces:
