Which antitrust law would prohibit a merger between two firms that produce along the same value chain for a certain good?
Celler-Kefauver Act (the Celler-Kefauver Act extended the Clayton Act by restricting vertical and conglomerate mergers. Vertical mergers are between two companies producing different goods for one specific finished product. This gives more control over the value chain in the production process and could limit competition)
What is the reason behind why monopolies are allocatively inefficient?
Their price at the profit-maximizing level of output is greater than marginal cost. (If the price is greater than the marginal cost, society values the product more than its opportunity cost and then the monopoly could be producing more and increase efficiency.)
Allocative efficiency occurs when ________.
There is an optimal distribution of goods and services (This is because the price that consumers are willing to pay is equal to the marginal utility/benefit that they get and therefore there is not deadweight loss to society)
If a firm covers the cost of production for its product and also adds a 15% profit to the price it charges its customer, then this is considered ________.
cost-plus regulation (This describes the policy where the price charged by the monopoly corresponds to cost of production + 15%)
If a monopolist increases quantity sold by one unit, by now selling total output at a slightly lower price,
marginal revenue is lower than the new price for that extra unit sold.
What is one of the difficulties that emerges when the government uses price regulation? This can sometimes compromise ________.
market competition
Horizontal mergers are
mergers between companies that sell the same output, or the same type of product.
Conglomerate Mergers are
mergers between companies with unrelated outputs.
In some cases, barriers to entry may lead to
monopoly
restrictive practices:
practices that reduce competition but that do not involve outright agreements between firms to raise prices or to reduce the quantity produced
A firm can renew a trademark over and over again, as long as it
remains in active use.
If a monopolist increases quantity by one unit, but sells the increased output at a slightly lower price:
the marginal revenue curve must be below the demand curve
Setting the price too high will result in a low quantity sold, and
will not bring in much revenue.

Sherman Antitrust Act (1890)
First federal action against monopolies, it was signed into law by Harrison and was extensively used by Theodore Roosevelt for trust-busting. However, it was initially misused against labor unions
Three things are necessary for effective price discrimination.
First, the firm needs to have at least some market power. If it has no market power, then it can't charge different prices for different customers. Second, the firm needs to be able to sort the customers into those willing to pay a higher price and those who are no, but who would be willing to pay a lower price. Identifying these groups of customers is difficult, since customers don't usually wear signs to that effect. Often firms create a situation where customers reveal themselves. Why do movie theaters charge lower prices for matinees (i.e showings before evening?) The answer is because usually it's young people and retired people who go to matinees because they don't have the money to pay full price. Why don't other adults go to matinees? The answer is because they tend to work during the day (or have other things to do during weekend days). The last thing necessary for price discrimination is the inability for customers to resell the product.

Government allows barriers to entry to limit competition (This is a type of monopoly where laws prohibit (or severely limit) competition
Analyze different strategies to control monopolies.
Governments use laws and regulation to reduce the inefficiency of monopolies. Regulated monopolies supply more than they otherwise would in return for a guaranteed profit.
Allocative efficiency, the optimal quantity of some output, is benefited by price discrimination for a monopolist by ________.
Greater Profits (the benefit of price discrimination to the monopolist is greater profits, of course, but it also increase productive and allocative efficiency because more produced is produced and is made available to a greater market than would otherwise be provided by the monopoly. As a result, more people can afford to buy the good in question and a greater level of allocative efficiency is achieved.)
Which of the following are considered barriers to entry?
Heavy spend on advertising by established companies
Which of the following are considered barriers to entry?
Heavy spending on advertising by established companies. (Name recognition and image can be a barrier. For examples, it would be very expensive to compete with firms like Apple, Microsoft or Amazon.)
What is price discrimination?
It is defined as charging different prices to different customers for the same product.
What does it mean when a firm uses a trademark as a legal monopoly?
It is using an identifiable name or symbol. (A firm can register a name or symbol for their sole use such as the apple for Apple, the golden arches for Mcdonald.)

When does price discrimination take place?
When a business can charge different prices to different customers based on their willingness to pay. (Firms can charge different prices for the same product because customers do not all have the same willingness to pay. The more willing, the higher the price.)

Which is the profit-maximizing level of output for a monopoly?
Where marginal revenue is equal to marginal cost.
If P > MC, then the marginal benefit to society (as measured by P) is greater than the marginal cost to society of producing additional units, and
a greater quantity should be produced.
Because of the perceived downward sloping nature of a monopolist's demand curve, the monopolist will charge a relatively low price at ________
a high level of output

a market in which one firm merely has a very high market share.
A firm that holds a monopoly position in the market place is
a price maker
Bundling
a situation in which multiple products are sold as one
Tying Sales

an increase in competition leading to greater innovation, more services, and lower prices
However, both mergers and acquisitions lead to two formerly separate firms being under common ownership,
and so they are commonly grouped together.
Thus, in markets with significant barriers to entry, it is not true that abnormally high profits will attract new firms,
and that this entry of new firms will eventually cause the price to decline so that surviving firms earn only a normal level of profit in the long run.

but instead it has the power to choose its market price.
Predatory pricing is a violation of U.S. antitrust law,
but it is difficult to prove.
Selling more output raises revenue,
but lowering price reduces it.
The idea is to provide limited monopoly power so that innovative firms can recoup their investment in R&D,
but then to allow other firms to produce the product more cheaply once the patent expires.
Second, the firm needs to be able to sort the customers into those willing to pay a higher price and those who are no,
but who would be willing to pay a lower price.
If the marginal revenue is higher than marginal cost, then a monopoly can increase profit
by producing one more unit of output.
For some products, the government erects barriers to entry
by prohibiting or limiting competition.

downward sloping; horizontal
Because the monopolist is the only firm in the market, its demand curve

City Gas is a natural monopoly that supplies natural gas to a particular city. Its cost and demand information are given below. If the government decides to regulate this natural monopoly by forcing them to produce at the point where the demand curve intersects average cost, then compared to the unregulated natural monopoly, the price will ________ and the quantity will ________.
fall, rise
Price discrimination occurs when a:
firm charges a different price for the same product based on demand differences
Price discrimination occurs when a
firm charges different prices to different customers based on their willingness to pay.
A perfectly competitive demand curve is considered to be ________ while a monopoly demand curve is considered to be ________.
flat; downward-sloping (A perfectly competitive firm perceives the demand curve that it faces to be flat. The flat shape means that the firm can sell either a low quantity or a high quantity at exactly the same price. A monopolist perceives the demand curve that it faces to be the same as the market demand curve, which for most goods is downward-sloping. Thus, if the monopolist chooses a high level of output, it can charge only a relatively low price; conversely, if the monopolist chooses a low level of output , it can then charge a higher price. The challenge for the monopolist is to choose the combination of price and quantity that maximizes profits.)

The effectiveness of price regulation and antitrust policy is rooted in allowing fair competition yet can ________.
have unintended consequences (All market-based economies operate against a background of laws and regulations, including laws about enforcing contracts, collecting taxes, and protecting health and the environment. The government policies discussed in this module-like blocking certain anticompetitive mergers, ending restrictive practices, imposing price cap regulation on natural monopolies, and deregulation-demonstrate the role of government to strengthen the incentives that come with a greater degree of competition.)
Some [mergers] are likely to lessen competition. That, in turn, can lead to

Suppose demand for a monopoly's product falls so that its profit-maximizing price is below average variable cost. How much output should the firm supply? (Hint: draw the graph and identify the break-even and shutdown points.)
it should shutdown and not produce output
Conversely, setting the price too low may result in a high quantity sold, but because of the low price,
it will not bring in much revenue either.
If Congress reduced the period of patent protection from 20 years to 10 years, what would likely happen to the amount of private research and development?
it would make innovation less lucrative, so the amount of research and development would likely decline.

A monopolist is a price-
maker
A monopolist can determine its profit-maximizing price and quantity by analyzing the marginal revenue and marginal costs of producing an extra unit. If the marginal cost curve is upwardly sloping and the marginal revenue curve is downward-sloping then it should following the ________ for profit maximizing.
marginal principle (For a monopoly marginal revenue decreases as it sells additional units of output. The marginal cost curve is upward-sloping. the profit-maximizing choice for the monopoly will be to produce at the quantity where marginal revenue is equal to marginal cost: that is, MR=MC. If the monopoly produces a lower quantity, then MR>MC at those levels of output, and the firm can make higher profits by expanding output. If the firm produces at a greater quantity, then MC>MR, and the firm can make higher profits by reducing its quantity of output.)
Total profit is maximized where
marginal revenue equals marginal cost.
The largest cattle rancher in a given region will be unable to have a ________ when sufficient numbers of smaller cattle ranchers provide sources of competition.
monopoly
In general, if a firm produces a product without close substitutes, then the firm can be considered a
monopoly producer in a single market.
By reducing the deadweight loss of social surplus price discrimination is
more allocatively efficient.
A/an ________ monopoly occurs when the scale economies in production or control of natural resources are so large or strong that only one firm can make a profit in that industry.
natural (A natural monopoly occurs where the economics of an industry naturally lead to a single firm dominating the industry. Economies of scale and sole ownership (or control) of a natural resource are two common examples of natural monopoly
There are two main types of monopolies that differ in they ways they exploit barriers of entry:
natural monopolies and legal monopolies.
A ________ exists when the quantity demanded in the market is less than the quantity at the bottom of the long-run average cost curve.
natural monopoly
A __________________ exists when the quantity demanded in the market is less than the quantity at the bottom of the long-run average cost curve.
natural monopoly
Economies of scale and sole ownership (or control) of a natural resource are two common examples of
natural monopoly.
Another type of natural monopoly occurs when a company has sole ownership (or majority control) of a scarce physical resource for which there are
no close substitutes.
But if buyers have a range of similar—even if not identical—options available from other firms, then the firm is
not a monopoly.
These industries offer an example where, because of economies of scale, one producer can serve the entire market more efficiently than a
number of smaller producers that would need to make duplicate physical capital investments.
Mono means
one
Roughly speaking, patent law covers __________ and __________ law protects an author's original books.
original inventive creations; copyright
In other words, total costs increase with
output at an increasing rate.
Following the assumption that firms maximize profits, how will the price and output policy of an unregulated monopolist compare with ideal market efficiency?
output will be too small and its price too high
Following the assumption that firms maximize profits, how will the price and output policy of an unregulated monopolist compare with ideal market efficiency?
output will be too small and its price too high.
If a legal monopoly owns the exclusive rights to a good for 20 years, it has a ________ for that good.
patent
Government ______________ regulations specify that inventors will maintain exclusive legal rights to their respective inventions for ______________ .
patent; a limited time
Examples of intellectual property rights provided to legal monopolies include
patents, trademarks, and trade secret law (Taken together, this combination of patents, trademarks, copyrights, and trade secret law is called intellectual property, because it implies ownership over an idea, concept, or image, not a physical piece of property like a house or a car. Countries around the world have enacted laws to protect intellectual property, although the time periods and exact provision of such laws vary across countries.)

A new skateboard company, "Sk8ters" opens its doors across the street from the town's existing skateboard company "Skate House". Skate House has a big clearance sale that lasts for four month and drastically undercuts its prices. After four months of dismal sales Sk8ters closes its doors unable to sell its products or compete with Skate House's prices. In the fifth month Skate House raises its prices back to regular prices. This is an example of what type of restrictive practice?
predatory pricing
Which of the following statements is true about price discrimination In the United States.
price discrimination is permitted
However, in the case of monopoly, at the profit-maximizing level of output,
price is always greater than marginal cost.
Why is a monopoly allocatively inefficient?
price is greater than marginal cost at the profit maximizing level of output
A monopolist
produces a product with no close substitutes.
When marginal profit turns negative,
producing more output will decrease total profits.
As long as marginal profit is positive,
producing more output will increase total profits.
Allocative Efficiency
producing the optimal quantity of some output; the quantity where the marginal benefit to society of one more unit just equals the marginal cost
In the event that Only1Corp. obtains control of all the natural gas producers in the US, it would most likely
raise prices, cut production, and realize positive economic profits.
. As a consequence, the government allows producers to become
regulated monopolies, to insure that an appropriate amount of these products is provided to consumers.
The result of ________ is that government price regulation can often become a way for existing competitors to work together to reduce output, keep prices high, and limit competition.
regulatory capture
When government price regulations paves a way for competitors to band together to reduce output, keep away competition and keep prices high it is known as ________.
regulatory capture
The horizontal demand curve means that, from the viewpoint of the perfectly competitive firm, it could sell either a
relatively low quantity like Ql or a relatively high quantity like Qh at the market price P.
Deregulation
removing government controls over setting prices and quantities in certain industries
When considering cost and revenue curves for a monopolist, the total cost curve will ________ then ________. The total revenue curve will ________ then ________.
rise, increase rapidly; rise, fall (The total cost curve is upward-sloping. Profits will be highest at the quantity of output where total revenue is most above total cost. the profit-maximizing level of output is the same as the revenue-maximizing level of output, which should make sense, because profits take costs into account and revenues do not. Total revenue for a monopoly first rises, then falls. Low levels of output bring in relatively little total revenue, because the quantity is low. High levels of output bring in relatively less revenue, because the high quantity pushes down the market price.)
City Electric is a natural monopoly that supplies electricity to a medium sized city. The cost and demand information are in the table below. If the government decides to regulate this natural monopoly by forcing them to produce at the point where the demand curve intersects average cost, then compared to the unregulated natural monopoly, the quantity will ________ and the price will ________.
rise; fall
Which of the following is least likely to present a barrier to entry into a market?
scientific cooperation
Monopoly is a
single supplier, the only firm in an industry
while a broadly defined market will tend to make it appear
smaller.
The last thing necessary for price discrimination is the inability for customers to resell the product. If a grocery store charged a higher price for female shoppers and a lower price for male shoppers,
smart females would simply ask their male associates to shop for them.
As a result, one firm is able to supply the total quantity demanded in the market at lower cost than two or more firms—
so splitting up the natural monopoly would raise the average cost of production and force customers to pay more.
Of the following examples, which has the potential to lead to domination in an industry by a monopoly?
sole ownership of a natural resource
Which one of the following is the most accurate description of a monopolist?
sole producer of a product for which good substitutes are lacking in a market with high barriers to entry
The total revenue curve for a monopolist will
start low, rise, and then decline.
Barriers to entry can range from the simple and easily surmountable, .
such as the cost of renting retail space, to the extremely restrictive
What qualities would ideally suit a monopolistic firm with regard to barriers to entry?
sufficient strength to prevent or discourage potential competitors from entering the market
Herfindahl-Hirschman Index (HHI). The HHI, as it is often called, is calculated by
summing the squares of the market share of each firm in the industry.
Thus, consumers will suffer from a monopoly because it will sell a lower quantity in the market, at a higher price,
than would have been the case in a perfectly competitive market.
Even though there are very few true monopolies in existence, we do deal with some of those few every day, often without realizing it:
the U.S. Postal Service, your electric and garbage collection companies are a few examples.
The following figure shows the average cost curve, demand curve, and marginal revenue curve for a monopolist. After maximizing profits, what do the firm's profit's equal?
the area of rectangle BDEG
If an industry is perfectly competitive or monopolistically competitive, then the government has relatively little reason for concern about:
the degree of monopoly power possessed by firms
The figure below shows the demand curve and the long run average cost curve for an electric company. This market is a natural monopoly because
the demand curve intersects the long run average cost curve at a point where the long run average cost curve is downward sloping
As output increases, marginal revenue decreases twice as fast as demand, so that
the horizontal intercept of MR is halfway to the horizontal intercept of demand.
Since a monopolist faces a downward-sloping demand curve,
the only way it can sell more output is by reducing its price.
Four-Firm Concentration Ratio
the percentage of the total sales in the industry that are accounted for by the largest four firms
Market Share
the percentage of total sales in the market
Nearly all monopolies in the U.S. are regulated monopolies, meaning
the prices they charge have to be reviewed and approved (or not) by a regulatory branch of the government.
First, the firm needs to have at least some market power. If it has no market power,
then it can't charge different prices for different customers.
If the marginal revenue exceeds the marginal cost,
then the firm can increase profit by producing one more unit of output.
Rather, it's because they are allocatively inefficient, in other words,
they produce too little of the product, and because (often) they are productively inefficient, that is, they don't produce as cheaply as possible.
Antitrust laws give government the power to block certain mergers, and even in some cases to break up large firms into smaller ones, in order to ________.
to protect consumers from predatory business practices (Antitrust laws are passed to protect consumers from predatory business practices, promote fair competition, and prevent price gouging)
When considering a competition policy for a natural monopoly, the optimal move is ________.
to set the price where AC crosses the demand curve
Which of the following describes the typical shape of the monopolist's total cost curve?
total costs decrease and become flatter as output rises (wrong)
Profits for a monopoly will be highest at the point where
total revenue is most above total cost. (Profit is maximized when the difference between revenue and cost is the largest with revenue higher than cost.)
The total cost curve for a monopolist is
upward sloping
Most legal monopolies are considered
utilities—products necessary for everyday life—that are socially beneficial to have.
This typically happens when fixed costs are large relative to
variable costs.
Natural monopolies often arise in industries where the marginal cost of adding an additional customer is
very low, once the fixed costs of the overall system are in place.
Acquisition
when one firm purchases another
In the economy, allocative efficiency takes place
when the mix of goods and services is at its ideal or optimal.
Price Cap Regulation
when the regulator sets a price that a firm cannot exceed over the next few years
Merger
when two formerly separate firms combine to become a single firm
One is legal monopoly,
where laws prohibit (or severely limit) competition.
As the quantity sold becomes higher, at some point the drop in price is proportionally more than the increase in greater quantity of sales, causing a situation
where more sales bring in less revenue. In other words, marginal revenue is negative.
The other is natural monopoly,
where the barriers to entry are something other than legal prohibition.
Natural monopoly occurs
where the economics of an industry naturally lead to a single firm dominating the industry.
A decreasing cost industry exhibits economies of scale,
where the technology is such that the scale of operation matters, so that the long run average cost of production is lower for a large firm than for a small one.
Mergers can also be lateral,
where two firms of similar sizes combine to become one.
Monopolies have monopoly power,
which is the ability to set the market price
Because the monopolist is the only firm in the market, its demand curve is the same as the market demand curve,
which is, unlike that for a perfectly competitive firm, downward-sloping.
A perfectly competitive firm will also find its profit-maximizing level of output where MR = MC. The key difference with a perfectly competitive firm is that in the case of perfect competition, marginal revenue is equal to price (MR = P),
while for a monopolist, marginal revenue is not equal to the price, because changes in quantity of output affect the price.
