Managing in Competitive, Monopolistic, and Monopolistically Competitive Markets
WHEN FIRMS IN A COMPETITIVE INDUSTRY SUSTAIN LOSSES, THEY WILL _____ THE INDUSTRY IN THE LONG RUN.
exit
when firms in monopolistic competition sustain economic losses, firms tend to _____ the market.
exit
a market with many "small" buyers and sellers, identical products, no transaction costs, and free entry and exit where buyers and sellers have perfect information is called _____.
perfect competition
if the market for corn contains many buyers and sellers (none of whom can influence price), a homogenous product, and free entry in the market, we consider the market to be _____
perfectly competitive
in a perfectly competitive market, the individual producer's demand curve is the market _____
price
in perfect competition, marginal revenue is equal to market _____.
price
the demand curve faced by a monopolist is
the same as the market demand curve
in the long run profits in a perfectly competitive industry are _____.
zero
IN THE LONG RUN, FIRMS IN MONOPOLISTIC COMPETITION PRODUCE A LEVEL OF OUTPUT WHERE
ATC > minimum average costs P > MC P = ATC
which of the following is NOT a reason why economies of scope can lead to monopolies.
Average costs fall as output increases
long-run properties of perfect competition include:
P = MC P = min AC
assuming P > AVC, a profit-maximizing firm, in a perfectly competitive market, produces a level at which,
P = MR P = MC MR = MC
to maximize profits, a perfectly competitive firm should produce in the range of increasing marginal cost where P = MC and
P is greater than or equal to AVC
the demand curve for a perfectly competitive firm is a _____ line at the market ______.
- horizontal - price
if p exceeds avc but is less than ATC, the firm
- is sustaining a loss - should remain open
the short-run supply curve for a perfectly competitive firm is the portion of the _____ cost curve that lies _____ the minimum average variable cost
- marginal - above
what happens in a perfectly competitive industry when firms earn profits?
- profits of remaining firms fall - price falls - supply increases
For a monopolist, a price _____ is necessary to increase output by one unit. As a result, the price received from all previous units _____.
- reduction - decreases
If P is less than AVC, the firm ____.
- should shut down - is sustaining a loss
a firm should shut down when P ___ AVC?
<
since each producer in a perfectly competitive market has no influence on market price, the demand curve for the individual firm is
a horizontal line equal to the market price.
the monopolist is restricted to price-quantity combinations that lie on the demand curve as a result of decisions made by
consumers
when increasing the output of one product reduces the marginal cost of another product, it is called
cost complementarity
revenues and _____ are both determinants of profits
costs
the welfare loss to society due to the level of output produced by a monopolist is called _____ loss of monopoly
deadweight
when a single firm earns profits due to high volume and reduced average costs, while two competing firms sustain losses, a monopoly can result. this is due to
economies of scale
a perfectly competitive firm maximizes profits at the level of output such that market price _____ marginal cost (MC)
equals
the profit-maximizing level of output occurs where the marginal revenue (MR) _____ marginal cost (MC).
equals
what would happen to research and development of new products and technologies if the U.S. eliminated the current patent system?
firms would have less incentive to develop new products
in the short run, when a firm shuts down, losses equal _____ costs.
fixed
which of the following is NOT a source of monopoly power?
free entry and exit
how does the U.S. patent system create monopolies?
grants an investor exclusive right to sell the product
how can cost complementarities create monopolies?
greater capital requirements of multi product firms act as a barrier to entry
a monopolist charges a _____ price and produces _____ output than a perfectly competitive industry.
higher; less
determine a key difference between monopolistic competition and monopoly.
in monopolist competition, there are other firms that sell similar products.
if MR is greater than MC, then increasing output
increases revenue by more than cost
a monopolist faces a downward-sloping demand curve. as a result,
it can choose a price or a quantity, but not both.
in the long run, a firm in monopolistic competition produces _____ output than is socially desirable.
less
for a monopolist, the marginal revenue curve has twice the slope of the demand curve. This implies
marginal revenue is less than price.
how is price determined in a perfectly competitive market?
market supply and market demand
fast-food hamburgers are characterized by a large group of sellers producing slightly different goods. What type of market is this?
monopolistic competition
when many buyers and sellers freely enter and exit a market having similar, yet differentiated products, it is called _____
monopolistic competition
suppose a market contains one supplier of a good that has no close, available substitutes. What type of market structure is this?
monopoly
when price (P) exceeds minimum average variable cost (AVC), each unit of output sold generates _____ revenue than the cost per unit of the variable inputs.
more
since a monopolist is the sole provider of a good or service, it has
more market power than if it faced competition
in order to maximize profits in the short run, a manager must determine how much output to produce given
only variable inputs within his control
in general, agriculture is considered a _____ _____ market
perfectively competitive
what is the price elasticity of demand facing an individual firm in perfect competition?
perfectly elastic
determine a fundamental difference between monopolistic competition and perfect competition.
products in monopolistic competition are differentiated
as firms exit a perfectly competitive industry in the long run, what happens to the profits of the remaining firms?
profits increase due to increased market price
on a graph, profits are given by the vertical distance between the cost function and the _____ line
revenue
a period of time during which at least one input is fixed is called the _____ run.
short
in a monopoly, where the firm chooses output based on marginal revenue (which is less than price),
supply curves do not exist.
in a perfectly competitive market, where firms choose output based on price,
supply curves exist
what happens to the industry supply as firms exit a perfectly competitive industry in the long run?
supply decreases
at the point where the cost curve C(Q) and the revenue line R(Q) are the farthest vertical distance apart, what is true of the slopes of these lines?
the slopes are equal
what is the key difference in determining the profit-maximizing price and output under monopoly versus monopolistic competition?
there is no difference
to maximize profits, at what level does a monopolistically competitive firm produce?
where MR(Q) = MC(Q)
In order to maximize profits, firms should take production to the point where marginal profits are
zero
if consumers are willing to pay more for "Roper's rice" than they are for "rice by russell", then "roper's rice" is enjoying additional value due to ____
brand equity
