Document Summary

Four main types of market structure (based on the # of firms in the industry and product differentiation): perfect competition, monopoly, oligopoly, and monopolistic competition. The key difference between a monopoly and a perfectly competitive industry is that a single perfectly competitive firm faces a horizontal demand curve but a monopolist faces a downward- sloping demand curve. Natural monopolies can still cause deadweight losses. To limit these losses, governments sometimes impose public ownership and at other times impose price regulation. Monopolist: a firm that is the only producer of a good with no close substitutes. Market power: the ability of a producer or firm to raise prices. Barrier to entry: something that prevents other firms from entering an industry. This can take the form of: control of natural resources or inputs, increasing returns to scale, technological superiority and government- created barriers including patents and copyrights. Crucial in protecting the profits of a monopolist.

A. A competitive firm

can consider only its location in setting the price.
must base its competitive price on product differentiation.
has the ability to set its own price.
must accept the price determined by the intersection of the market supply and demand curves.
has no supply curve.

B. If a firm is making an economic profit, then

the factors of production are being paid their opportunity costs.
there will be no change in the number of firms if the industry is perfectly competitive.
the factors of production are being paid less than their opportunity costs.
the factors of production are being paid more than their opportunity costs.
the firm will exit the industry

C. Along a downward-sloping monopoly demand curve,

marginal revenue is greater than price.
the elasticity of demand is constant.
marginal revenue decreases when the price decreases.
marginal revenue is equal to zero when the price is equal to zero

D. If, in the short run, a perfectly competitive firm is producing at a point where the total cost is greater than total revenue, then the firm should

shut down because economic profits are negative.
continue to produce as long as P > AVC.
continue to produce because accounting profits are positive.
set a higher price for its output.
set a lower price for its output

E. For a perfectly competitive firm, the demand curve is

the marginal revenue curve.
perfectly inelastic.
always equal to marginal cost.
the same as the market demand curve

F. A firm in a(n) industry will have the most elastic demand curve

monopolistic
oligopolistic
monopolistically competitive
perfectly competitive

G. If the demand curve of a monopolist is in the inelastic range, then

total revenue will fall if the price increases.
total revenue will be unchanged if the price increases.
total revenue will rise if the price increases.
the total supply will increase by an equal amount if demand increases.
the price will be unchanged if total revenue increases

H. Monopolistic competition and oligopoly are examples of

monopoly.
perfect competition.
theories of consumer behavior.
imperfect competition.
the extreme cases on the market structure continuum

I. Under which market structure do firms face the flattest (most elastic) demand curve?

perfect competition
monopolistic competition
oligopoly
monopoly

J. At the point of long-run equilibrium for a perfectly competitive firm,

economic profits are zero.
TR > TC.
TR < TC.
P = AVC.
normal profits are zero.

1. A perfectly competitive firm will continue producing in the short run as long as it can cover its:

A.total cost.
B.average total cost.
C.average variable cost.
D.average fixed cost.

2. A perfectly competitive firm will earn a profit and will continue producing the profit-maximizing quantity of output in the short run if price is:

A.greater than marginal cost.
B.less than marginal cost.
C.less than average variable cost.
D.greater than average total cost.

3. Monopolistic competition is an industry characterized by:

A.a product with many close substitutes.
B.a horizontal demand curve.
C.a small number of firms.
D.barriers to entry and exit.

4. If a perfectly competitive firm increases production from 10 units to 11 units, and the market price is $20 per unit, total revenue for 10 units is:

A.$10.
B.$20
C.$200.
D.$210.

5. The demand curve facing a monopolist is:

A.horizontal, the same as that facing a perfectly competitive firm.
B.downward sloping, the same as that facing a perfectly competitive firm.
C.upward sloping, the same as that facing a perfectly competitive firm.
D.downward sloping, unlike the horizontal demand curve facing a perfectly competitive firm.

6. Suppose that a monopolist increases production from 10 units to 11 units. If the market price declines from $30 per unit to $29 per unit, marginal revenue for the eleventh unit is:

A.$1.
B.$9.
C.$19.
D.$29.

7. Most electric, gas, and water companies are examples of:

A.unregulated monopolies.
B.natural monopolies.
C.restricted-input monopolies.
D.sunk-cost monopolies.

8.If a perfectly competitive firm is producing a quantity that generates P > MC, then profit:

A.is maximized.
B.can be increased by increasing the price.
C.can be increased by decreasing the price.
D.can be increased by increasing production.

Homework help and study guide help, all multiple choice

A monopolist:

A) can sell as much as it wants at the chosen price because it is the only seller.

B) can increase the price only if it is willing to decrease the quantity sold.

C) can increase the price and the quantity sold at the same time.

D) is not restricted by the law of demand.

A monopolistically competitive firm:

A) produces where marginal revenue equals marginal cost and charges the price consumers are willing to pay as given by the demand curve.

B) produces where marginal cost equals average total cost and charges the price consumers are willing to pay as given by the demand curve.

C) chooses price and quantity based on where the marginal cost curve meets the demand curve.

D) chooses price and quantity based on where the average total cost curve meets the demand curve.

21) Oligopoly is A) like a monopoly because there are barriers to entry. B) like perfect competition because oligopoly firms all sell homogeneous goods. C) like monopolistic competition because oligopoly firms all sell differentiated goods D) like perfect competition because there are many firms in the industry
