micro econ test 4
Does the market system result in productive efficiency? In the long run, perfect competition
results in productive efficiency because firms enter and exit until they break even where price equals minimum average cost.
Economists generally agree that efficiency losses due to monopolies in the economy are
small because true monopolies are very rare.
According to Joseph Schumpeter, what does economic progress depend on?
technological change in the form of new products
What is the relationship between a perfectly competitive firm's marginal cost curve and its supply curve?
A firm's marginal cost curve is equal to its supply curve for prices above average variable cost.
What is the relationship between a monopolist's demand curve and the market demand curve? What is the relationship between a monopolist's demand curve and its marginal revenue curve?
A monopolist's demand curve is the same as the market demand curve. A monopolist's marginal revenue curve has twice the slope of its demand curve, because to sell more output, a monopoly must lower price.
Compared to perfect competition, when a consumer purchases a product from a monopolistically competitive firm, the consumer benefits from purchasing a product
that is appealing because it is differentiatedis appealing because it is differentiated.
When are firms likely to enter an industry? When are they likely to exit?
Economic profits attract firms to enter an industry, and economic losses cause firms to exit an industry.
difference between productive and allocative efficiency
Productive efficiency pertains to production within an industry while allocative efficiency pertains to production across all industries.
Which of the following is an expression of profit for a perfectly competitive firm? Profit for a perfectly competitive firm can be expressed as
Profit equals (P- ATC) x Q, where P is price, Q is output, and ATC is average total cost.
Suppose a second seafood restaurant opens in Stonington, Maine. Consumer surplus and economic efficiency will
increase so long as the two firms compete
Which of the following statements is true when the difference between TR and TC is at its maximum positive value?
both A and B MR = MC Slope of TR = Slope of TC
How does perfect competition lead to allocative and productive efficiency?
both a and b.
How is the market supply curve derived from the supply curves of individual firms? The market supply curve is derived
by horizontally adding the individual firms' supply curves.
Suppose Farmer Lane grows and sells cotton in a perfectly competitive industry. The market price of cotton is $1.54 per kilogram, and his marginal cost of production is $1.56 per kilogram, which increases with output. Assume Farmer Lane is currently earning a profit. Can Farmer Lane do anything to increase his profit in the short run? Farmer Lane
can increase his profit by producing less output.
Assume that an industry that began as a perfectly competitive industry becomes a monopoly. Compared to when the industry was perfectly competitive, the monopolist will
charge a higher price and produce less output.
Unlike perfectly competitive firms, in the long run monopolistically competitive firms
charge a price greater than marginal cost and do not produce at minimum average total cost.
Explain why market power leads to deadweight loss.
charge a price that is greater than marginal cost to maximize profits.
In 2017, Apple reported that since its iTunes App Store had opened in 2008, third-party app developers had earned more than $60 billion and currently employed 1.4 million people. Yet, as we've seen, because of intense competition, many game developers can only break even on the games they develop. If game companies can only break even on the mobile games they develop, in the long run, we would expect them to
continue to develop mobile games because they can cover all costs of production if they break even.
It is possible for profits to increase even if revenue decreases if how can GE maximize its profit
costs decrease more than revenue decreases increase revenues and increase costs
Network externalities
create barriers to entry because if a firm can attract enough customers initially, it can attract additional customers as its product's value increases by more people using it, which attracts even more customers. AND serve as barriers to entry because new products are less useful.
Suppose that a perfectly competitive industry becomes a monopoly. As a result, consumer surplus will ____, producer surplus will ___ and deadweight loss will___
decrease increase increase
A natural monopoly
develops automatically due to economies of scale.
Does a monopolist have a supply curve?
does not have a supply curve because it is a price maker with one profit-maximizing price-quantity combination.
Suppose the market for cotton is perfectly competitive and that input prices decrease as the industry expands. Characterize the industry's long-run supply curve. The cotton industry's long-run supply curve will be
downward sloping because thelong-run average cost of production will be decreasing
Market power results in
economic profits that can be spent on research to develop new products.
Compared to perfect competition, consumer welfare with monopolistic competition is
enhanced by products more closely suited to consumer tastesproducts more closely suited to consumer tastes.
Explain why it is true that for a firm in a perfectly competitive market that P = MR = AR
firms can sell as much output as they want at the market price
Unlike in perfectly competitive markets, in monopolistically competitive markets,
firms face downward-sloping demand curves, and the products competitors sell are differentiated.
According to an article in the New York Times, interest payments on bank loans make up more than half the costs of the typical solar panel manufacturer. The owner of a firm that imports solar panels made this observation about solar panel manufacturers: "So as long as companies can cover their variable costs and earn at least some revenue to put toward interest payments, they will continue to operate even at a loss." The interest payments these firms make are a The quote describes logical behavior of solar panel firms in the
fixed cost since they do not vary with output. short run
In a perfectly competitive industry with constant costs, the long-run supply curve will be
horizontal
What is the supply curve for a perfectly competitive firm in the short run? The supply curve for a firm in a perfectly competitive market in the short run is
that firm's marginal cost curve for prices at or above average variable cost.
How should firms in perfectly competitive markets decide how much to produce?
the difference between total revenue and total cost is as large as possible.
The four main reasons a firm becomes a monopoly are:
the government blocks entry, control of a key resource, network externalities, and economies of scale.
What is the government's policy on collusion in the United States? Explain the rationale for this policy. In the United States
the government makes collusion illegal with antitrust laws because monopolies reduce economic efficiency
How are prices determined in perfectly competitive markets?
the interaction of market demand and supply because firms and consumers are price takers.
Which of the following is a characteristic of perfectly competitive markets?
the products sold by all firms in the market will be identical
A firm is likely to be a monopoly if
there are important network externalities in supplying the good or service.
The federal government grants patents
to encourgae firms to spend money on research to create new products
In a perfectly competitive industry with increasing average costs, the long-run supply curve will be
upward sloping
What is meant by productive efficiency? Productive efficiency is
when a good or service is produced at lowest possible cost.
A monopolist is a price maker because
when a monpolist raises its prices, it loses some but not all customers.
When is a firm a monopoly, or are monopolies only theoretical concepts that do not exist?
A firm is a monopoly if its economic profits are not competed away in the long run.
Why would a firm produce in the short run while experiencing losses?
A firm would not shut down if by producing it would lose an amount less than its total fixed costsit would lose an amount less than its total fixed costs.
Which of the following best explains why firms don't maximize revenue rather than profit? If a firm decided to maximize revenue, would it be likely to produce a smaller or a larger quantity than if it were maximizing profit?
At the point where revenue is maximized, the difference between total revenue and total cost may not be maximized. larger
Why are consumers so powerful in a market system?
Because it is consumers' demand that influences the market price and dictates what producers will supply in the market.
A student argues: "To maximize profit, a firm should produce the quantity where the difference between marginal revenue and marginal cost is the greatest. If a firm produces more than this quantity, then the profit made on each additional unit will be falling." Is the above statement true or false?
False. Profit is maximized at the output level where marginal revenue equals marginal cost.
Which of the following is not likely to happen in the pencil market?
Firms will charge a price above marginal cost in the long run.
Would the only restaurant that sells British food in Palo Alto, or any other city, be considered a monopoly? What criteria would you use to determine if the restaurant is a monopoly?
It could be according to the broad definition, but would not be according to the narrow definition. The ability to ignore the actions of other firms, the persistence of economic profits, and the availability of close substitutes.
When a firm's demand curve slopes downward and the firm decides to cut price, which of the following happens?
It sells more units but receives lower revenue per unit.
"In a perfectly competitive market, in the long run consumers benefit from reductions in costs, but firms don't." Don't firms also benefit from cost reductions because they are able to earn greater profits?
No. Because short-run profits encourage entry, firms earn zero economic profit in the long run.
If marginal revenue slopes downward, which of the following is true?
The firm must decrease its price to sell a larger quantity.
A student in a principles of economics course makes the following remark: "The economic model of perfectly competitive markets is fine in theory but not very realistic. It predicts that in the long run, a firm in a perfectly competitive market will earn no profits. No firm in the real world would stay in business if it earned zero profits." Is this remark correct or incorrect?
The remark is incorrect because the student has confused accounting profit and economic profit. Firms in a perfectly competitive market earn accounting profit, but no economic profit.
The chapter states, "Firms will supply all those goods that provide consumers with a marginal benefit at least as great as the marginal cost of producing them." A student objects to this statement by making the following argument: "I doubt that firms will really do this. After all, firms are in business to make a profit; they don't care about what is best for consumers." After reminding the class that we are assuming a competitive market, your professor would most likely give the following reply.
While it's true that firms don't care about consumer welfare, they do maximize profits by producing the efficient level of output.
Why do single firms in perfectly competitive markets face horizontal demand curves?
With many firms selling an identical product, single firms have no effect on market price.
Are perfectly competitive markets allocatively efficient in the long run?
Yes comma because firms produce where the marginal benefit to consumers equals the marginal cost of production.
If you own the only hardware store in a small town, do you have a monopoly?
Yes. You would have a monopoly if your profits are not competed away in the long run.
A public franchise is
a firm designated by the government as the only legal provider of a good or service
An example of a public franchise is
a firm that is the sole, government-designated provider of electricity, and an example of a public enterprise is the government directly providing sewage service.
what is a price taker? when are firms likely to be price takers?
a firm that is unable to affect the market price it sells a product that is exactly the same as every other firm
A cartel is The NCAA acts like a cartel because it As a result of the NCAA acting like a cartel, If you are a student who does not play intercollegiate sports but who is enrolled at a school, such as the University of Alabama or Ohio State University, with prominent sports teams, the NCAA acting as a cartel makes you
a group of firms that collude by agreeing to restrict output to increase prices and profits. restricts the number of games that the member schools' teams can play. athletic departments benefit because they have lower costs, but athletes lose because they cannot be compensated for playing. worse off because you would have fewer games to watch and have to pay more to watch them.
The long-run supply curve is
a horizontal line equal to the minimum point on the typical firm's average total cost curve.
Which of the following terms best describes a state of the economy in which production reflects consumer preferences?
allocative efficiency
What is the difference between a firm's shutdown point in the short run and its exit point in the long run? In the short run, a firm's shutdown point is the minimum point on the Why are firms willing to accept losses in the short run but not in the long run?
average variable cost curve, while in the long run, a firm's exit point is the minimum point on the average total cost curve.
Substitutes exist for just about every product, so can a firm ever really be a monopoly? A firm can
be a monopoly if it can ignore the actions of other firms.
When a monopoly maximizes profit, deadweight loss will be larger if demand is
inelastic because price will be farther from marginal cost.
A monopoly that maximizes profit
is not also maximizing revenue because revenue is highest when marginal revenue equals zero. AND is not also maximizing production because price must be reduced to sell additional output.
What is meant by allocative efficiency? Allocative efficiency is when every good or service
is produced up to the point where price equals marginal cost.
A monopoly's demand curve
is the same as the demand curve for the product.
Economists could find that a firm is a monopoly if
it earns profis in the long run
Despite the fact that few firms sell identical products in markets where there are no barriers to entry, economists believe that the model of perfect competition is important because
it is a benchmark a market with the maximum possible competition that economists use to evaluate actual markets that are not perfectly competitive.
What are the three conditions for a market to be perfectly competitive? For a market to be perfectly competitive, there must be
many buyers and sellers all firms selling identical products no barriers to new firms entering the market
The increase in total revenue that results from selling one more unit of output is What is the relationship between price, average revenue, and marginal revenue for a firm in a perfectly competitive market?
marginal revenue Price is equal to both average revenue and marginal revenue.
In the long run, monopolistically competitive firms
may continue to earn profit by improving their product.
Compared to monopolies, perfectly competitive markets are
more economically efficient because they result in more economic surplus.
What determines entry and exit of firms in a perfectly competitive industry in the long run? In a perfectly competitive industry in the long run,
new firms will enter if existing firms are making a profit and existing firms will exit if they are experiencing losses.
The following questions are about long-run equilibrium in the market for cage-free eggs. As described in the chapter opener, the market for cage-free eggs in 2015 was In the long run in the market for cage-free eggs, we would expect With the stricter guidelines, other things equal, the market price of cage-free eggs would ____ as the minimum long-run average cost ___ At the new market price, the long-run equilibrium quantity will be_____
not in equilibrium because farmers who were raising cage-free chickens were earning higher profits than farmers who raised chickens using more traditional methods. the equilbrium price to decrease and the equilibrium quantity to increase, as more firms enter. increase, increases, smaller
An industry is a natural monopoly when
one firm can satisfy the entire market at the lowest cost
The distribution of electric power might be a natural monopoly because The generation of electric power would not be a natural monopoly because
only one distrubution network is needed to transmit the power generation can be done in various ways and in various locations, so there are no inefficiencies associated with multiple providers.
A monopolistically competitive firm is not allocatively efficient because
price exceeds marginal costs
A monopolistically competitive firm produces where _________, while a perfectly competitive firm produces where _________.
price is greater than marginal cost; price is equal to marginal cost
Which of the following terms best describes the result of the forces of competition driving the market price to the minimum average cost of the typical firm?
productive efficiency
Would a firm earning zero economic profit continue to produce, even in the long run? In long-run competitive equilibrium, a firm earning zero economic profit
will continue to produce because such profit is as high a return as could be earned elsewhere
When new firms enter a monopolistically competitive market, the economic profits of existing firms
will decrease because their demand curves will shift to the left. shift to the left and become more elastic.
If the demand for oranges increases, then the market
will supply additional oranges because producers seek the highest return on their investments.
In a situation in which the consumers in a housing development have only one cable company available, is the price really at the whim of the company? Would a company in this situation be likely to charge, say, $500 per month for basic cable services? Explain why or why not. A cable company in this situation
would not be free to charge any price it chooses because it would still be constrained by consumer demand.
In perfect competition, long-run equilibrium occurs when the economic profit is
zero
In the long run, the monopolist can earn
zero or positive economic profit.
Is zero economic profit inevitable in the long run for a monopolistically competitive firm?
No, a firm could try to continue making a profit in the long run by reducing production costs and improving its products.
Suppose you decide to open a copy store. You rent store space (signing a one-year lease), and you take out a loan at a local bank and use the money to purchase 10 copiers. Six months later, a large chain opens a copy store two blocks away from yours. As a result, the revenue you receive from your copy store, while sufficient to cover the wages of your employees and the costs of paper and utilities, doesn't cover all of your rent and the interest and repayment costs on the loan you took out to purchase the copiers. Should you continue operating your business?
Yes, because you are covering your variable costs.
With a downward-sloping demand curve, average revenue is equal to price With a downward-sloping demand curve, marginal revenue is below price
actually, average revenue is always equal to price, whether demand is downward sloping or not. because the firm must lower its price to sell additional units.
