Chapter 16: monopolistic competition: perfectly competitive market-0 economic profit, no deadweight loss, monopoly-profit economic profit, deadweight loss for society, exteremes forms for markets, most markets have elements from both, typical firm has some market power, The percentage of total output in the market supplied by the four largest firms. The 4 big firms concentration ratio is under 50% in canada. Highly concentrated industries include: breakfast cereal, aircraft manufacturing, electric lamp bulbs, household laundry equipment, second type is monopolistic competition, monopolistic competition: a market structure in which many firms sell products that are similar but not identical. Each firm has a monopoly over the product that it makes. Many sellers-many firms competing for the same group of customers. Product differentiation-each firm produces a product that is at least slightly different from those of other firms: each firm faces a downward-sloping demand curve. Free entry and exit-number of firms adjusts until economic profits are driven to 0.

32. Which of the following is not a difference between monopolies and perfectly competitive markets?

A. Monopolies face downward sloping demand curves while perfectly competitive firms face horizontal demand curves.

B. Monopolies charge a price higher than marginal cost while perfectly competitive firms charge a price equal to marginal cost.

C. Monopolies can earn profits in the long run while perfectly competitive firms break even.

D. Monopolies choose to produce the quantity at which marginal revenue equals marginal cost while perfectly competitive firms do not.

40. Which of the following statements is not correct?

A. Both monopolies and monopolistically competitive firms can earn economic profits in the long run.

B. Both monopolistically competitive and perfectly competitive firms can earn economic profits in the short run.

C. Only competitive firms produce the welfare-maximizing level of output.

D. Firms in perfect competition, monopolistic competition, and monopoly maximize profits by producing where marginal revenue equals marginal cost.

43. A monopolistically competitive firm is currently producing 20 units of output. At this level of output the firm is charging a price equal to $20, has marginal revenue equal to $12, has marginal cost equal to $12, and has average total cost equal to $18. From this information we can infer that

A. the profits of the firm are negative.

B. firms are likely to leave this market in the long run.

C. the firm is currently maximizing its profit.

D. All of the above are correct.

all of the time
some of the time
on rare occasions
none of the time

2. Economics Profit is:

the same as accounting profit
sales minus explicit costs and implicit costs
sales minus variable costs and fixed costs
opportunity cost only

monopoly
oligopoly
perfect competition
monopolistic competition

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.
