6. Market Structure Vocabulary

7. U.S. States Sue Big Music over Price-Fixing
This price-fixing lawsuit against the 5 major recording labels
charged that they increased the price of CDs in violation of
antitrust laws. “Because of these conspiracies, tens of millions of
consumers paid inflated prices to buy CDs of artists including
Santana, Whitney Houston, Madonna and Eric Clapton.” The FTC
estimated that the recording companies policies[$40 billion industry]
forced U.S. consumers to pay as much as $480 million more than
they should have for CDs and other music over the last three years.
Auto body shops sued paint companies, including Sherwin-Williams,
for fixing prices on paint, primer and fillers.
Four major toy manufacturers (Hasbro, Little Tykes, Mattel, & Toys R’Us)
were sued for conspiring to fix prices of toys. Toys R’Us was accused
of brokering an illegal agreement with toy manufacturers to not sell
their most popular products to the warehouse clubs.

9. among firms operating in the same market (autos).
3 Perfect Competition – has a very large number of sellers (hundreds or thousands) of the same product (any agriculture or fishery product). They are all selling the same undifferentiated products (oranges).
4 Competition – economic rivalry among businesses.
5 Market Structure – degree of competition
among firms operating in the same market (autos).

10. Perfect Competition and Price
Four Market Conditions Necessary For Perfect Competition
6A 1. Very large number of sellers (hundreds or thousands).
Each seller will have only a small share of the market.
B Similar or identical products (sweet corn/brocolli/eggs)
which means there is no reason for non-price competition.
C Easy entry and exit into the market.
D Absence of price controls (too many sellers & consumers).
Perfect Competition and Price
No one firm controls price. Lowering price would
lower profits as consumers would buy similar
substitutes. Prices are set by the market rather
than by the firms. These firms are “price takers.”

11. Sellers try to decrease competition by making their products different
20 Monopolistic Competition – fairly large number (25-75) of sellers competing to sell slightly differentiated products. Product differentiation (real or imaginary) is vital. This is the most common market structure.
Sellers try to decrease competition
by making their products different
from the others. Since each firm
attempts to make its product unique,
unique, there is an “element of monopoly”,
thus monopolistic competition.
Product differentiation, when it is successful, enables
a firm to “establish a kind of monopoly” so that loyal
customers will prefer it rather than buy from the
competition. [They try to monopolize a small portion
of the market.]

12. 21 Even virtually identical products may be differentiated
by brand name, packaging, or design but they are still
similar. They have all the conditions of perfect competition
except for product “differentiation.”
22 They use “nonprice” methods of competition such as
advertising and improved service to increase sales.
Reputation is important [builds loyalty]. Most manufactured
goods are made by only a few producers.

13. 4 Market Conditions For Monopolistic Competition
25-75 buyers and sellers must exist. Firms act independently
but no single firm is large enough to change the supply or
price of a good.
2. The products are similar but they emphasize product
differentiation (differences among products). This is the one
thing that separates monopolistic competition from perfect
competition.
The differences may be real or imaginary (a refrigerator with
plastic or metal trays). Aspirin, by federal law, has to have
certain chemicals but people believe highly advertised aspirin
is better. Revlon offers 157 shades of lipstick – 41 are pink.
3. Buyers must be well informed about differences in products.
Monopolistic competitors rely on informative and competitive
advertising.
4. Easy to enter or exit the industry. Few restrictions exist.

14. Examples of Monopolistic Competition
Monopolistic Competition [element of monopoly [differentiation uniqueness] so called monopolistic competition] This is the most common market structure – over 99% of all firms.
Examples of Monopolistic Competition
Blue Jeans Grocery Stores Candy Bars
Dry Cleaners Rock Concerts Pizza
Shoe Stores Cassette players Chicken
Toothpaste Book Stores Soaps and detergents
Restaurants Vacuum Cleaners Furniture Stores
Barbershops Beauty Parlors Econ Textbook Co’s
“Econ”

Air Conditioning Alcohol Treatment Centers
Auto Dealers Carpet Cleaning
Karate Fingernail Saloons
Body Shops Upholstery Cleaners
Pet Shops Tire Companies
Electrical Contractors Masonry Contractors
Window Cleaners Dry Wall Contractors
Dermatologists Party Suppliers
Copying Dog Grooming
Locksmiths Accountants

16. Monopolistic Competition and Price 23 There is some control over price because differentiation creates buyer loyalty [jeans]. Non-price competition is used to control price. Developing brand name loyalty will enable a firm to marginally increase price without losing customers. If the increase is too much, buyers will switch to a competitor’s product.
The “Real World”
The “real world” of competition involves
monopolistic competition & oligopolies. Over 99%
of all firms are monopolistic competitors. However,
a few thousand oligopolies produce most of the
products in the U.S. So, our big firms are oligopolists
and our smaller firms are monopolistic competitors.

17. Two Types of Oligopolies
24 Oligopoly – “the chosen few” (3 or 4) firms control 70% of the market.
Monopoly – 1 firm industry
(Cable TV)
Duopoly – 2 firm industry.
(Coke & Pepsi)
[P&G (47%) & Kim-Clark
(30%) in diapers]
“Oligo” – few in an industry.
(“Big 3 or 4” or even “Big 5 or 6”)
Two Types of Oligopolies
25 Pure (Undifferentiated) Oligopoly – 3 or 4 producers
dominate the production of an identical product (steel, zinc,
copper, aluminum, lead, cement, industrial alcohol)
Differentiated Oligopoly – 3 or 4 producers dominate the
production of differentiated (similar) products. [typewriters,
tires, soap, cigarettes, refrigerators, cereals, TVs & autos]

18. Duopoly – when 2 firms dominate an industry.
Coke products have 43% of the market and Pepsi products have 32%.
1. Coke Classic
2. Pepsi Cola
3. Diet Coke
4. Mountain Dew
5. Diet Pepsi
6. Sprite
7. Dr. Pepper
8. Caffeine Free Diet Coke

21. Four Market Conditions For Oligopolies 1
Four Market Conditions For Oligopolies 1. A few sellers control over 70% of market. 2. Firms offer identical or differentiated products (real or imaginary). Advertising important. 3. Product information must be easily available. They use informative advertisement (price, quality, and special features) to introduce new products. 4. There are huge barriers to entry into the industry. The three major barriers are technological knowledge, money, & brand name loyalty In 1980, it cost Ford $3 billion to equip a factory that would produce two new subcompacts Entry is difficult because many have patents or own essential raw materials. This makes it difficult for new firms to try to compete.
Oligopoly and Price
Oligopolies control price to some degree by creating
brand name loyalty and using non-price competition.

22. 26 Price Leadership – when one firm, usually the largest
and most powerful in the industry, offers a new product at a
certain price. The others then follow because they fear a
price war or because they would be better off financially by
doing so.
In other words, oligopolists play the game, “follow the leader”.
Price leadership is legal (unlike collusion) because it does
not involve any agreement among competitors. If the
competition does not follow the leader’s price, the leading firm
may be forced to change its price and fall in line with the prices
of the competition.
27 Collusion – a formal price agreement among competitors.
This is illegal because it presents a danger to free competition.
Even one from one manager to another is illegal.

23. Price-fixing In 1996, Archer Daniels Midland Company, one
of the country’s most influential corporations,
pleaded guilty to criminal price-fixing charges
and was fined $100 million. That fine was by
far the largest ever obtained by the Justice
Department in a price-fixing case. The charge
was that Archer Daniels conspired to fix the
prices of lysine, a feed additive, and citric acid,
used in a number of food products.

24. Price-Fixing Fines Vitamin Makers
Hoffman La Roche 40% $500 million fine
BASF AG 20% $225 million fine
Rhone-Paulene 15% Spilled the beans on co-conspirators
Both had to pay a total fine of $725 million because of massive
price-fixing that inflated the cost of everything from breakfast
cereal to hamburgers over the past decade. The suits were
brought by livestock farmers and other purchasers of bulk
vitamins who allege they were forced to pay illegally inflated
prices. It hurt every American consumer who took a vitamin,
drank a glass of milk, or had a bowl of cereal.

25. What was the result of the MIT 1993 Price-Fixing Case?
Eight Ivy League schools agreed
to stop colluding to fix prices, and
MIT was found guilty of price fixing.

27. 7 Pure Monopoly – one firm industry [“monopolist”]
Pure Monopoly’s Market Condition
1. One firm is the only seller. Advertising promotes image.
2. No close substitute goods are available.
8 3. Prohibitive barriers to entry in the industry. High invest-
ment costs and technological expertise prevent others from
entering the market. Legal restrictions make entry in
government-supported monopolies nearly impossible.
4. Almost complete control of market price.
9 Monopolist have much control over price because they are
the only seller. A higher price would hurt demand. The state
may control the price on some legal monopolies. These single
suppliers are “price makers.”

28. Four Types of Legal Monopolies
11 1. Natural Monopoly – where competition would be
chaotic, it is natural to give the business to one firm. Imagine
the confusion if 5 different busses raced each other
to the corner to pick up a passenger. Competition
would be impractical, inconvenient, & unworkable.
12 Examples: Public Utilities (electric & gas) – privately owned
companies (buses-Continental Trailways) but regulated by the
government. Comcast Cable TV in Plano. The government
monitors the natural monopolies to ensure that they provide
quality service at reasonable rates.
AT&T had a long-distance telephone natural monopoly for
75 years.
Greyhound
TXU Electric
Waste Management

29. Natural Monopoly
Where competition would be chaotic, therefore, it is natural to give the business to one firm
Ex’s are utility companies and cable TV
Market where average costs are lowest when all output is produced by a single firm
They are privately owned, but regulated by the government

30. & government monopolies [government owned] is
13 Government Monopoly – monopoly owned and operated by the government.
The difference between natural [privately owned]
& government monopolies [government owned] is
that these monopolies are owned operated by any
level of government.
Examples would be interstate highway system,
public libraries, public schools, Postal Service, & DART.
In most cases, government monopolies deal with
economic products needed for the public welfare
but which people would not be provided adequately
by private industry. Most tend to provide goods that
enhance the general welfare rather than seek profits.

32. Geographic Monopoly – when a firm is the only seller of a good in a specific location.

33. The “Last Chance Gas Station” is the last one within
50 miles of Mexico. A general Store in a remote
community has a monopoly because the area can’t
support two stores. Geographic monopolies are not
guaranteed.

34. Examples of Geographic Monopoly
“Last Chance Gas Station”
Last Chance Gas
A general store in the middle of nowhere

35. 14 4. Technological Monopoly – results from the
invention of a new product (patent) or when
technology changes the way a good is produced.
General Dynamics is the only defense contractor
with the technology to build Trident Submarines.
16 A patent gives an individual
or firm exclusive right to pro-
duce, use or dispose of an
invention or discovery for
20 years from the date of filing.
To obtain a patent, you must go to the Patent
Office after doing research to make sure the
patent has not already been patented. Then
You hire a patent lawyer to file your patent.
All of this takes about 18 months. The total
cost for a patent runs about $5,000.
17 It is very expensive to wage a patent
infringement suit, around $300,000.
Polaroid’s camera
patent prevailed
& won $929 million.
Polaroid had accused
Kodak of infringing
on instant photo
patents & it took 10
years to make it to
the Supreme Court.

38. Some Sad News Today About The Pillsbury Doughboy
A great icon of the entertainment community has died today
at age 71, the Pillsbury Doughboy.
He died yesterday of a yeast infection and complications from repeated pokes in the belly.
Doughboy was buried in a lightly greased coffin. Dozens of celebrities turned out to pay their respects, including Mrs. Butterworth, Hungry Jack, the California Raisins, Betty Crocker, the Hostess Twinkies, and Captain Crunch.
The gravesite was piled high with flours. Aunt Jemima delivered the eulogy and lovingly described Doughboy as a man who never knew how much he was kneaded.
Doughboy rose quickly in show business, but his later life was filled with turnovers. He was not considered a very smart cookie, wasting much of his dough on half-baked schemes. Despite being a little flaky at times he still, as a crusty old man, was considered a roll model for millions.
Doughboy is survived by his wife, Play Dough; two children, John Dough and Jane Dough; plus they had one in the oven. He is also survived by his elderly dad, Pop Tart.

45. Antitrust Legislation
Since the 1880s, the federal government had aided competition. To promote
efficiency, certain legal monopolies have been allowed to exist.
Trusts – legally formed combinations of corporations or companies.
In the latter half of the 1800s, cutthroat competition and mergers created trusts
in steel, meatpacking, oil, sugar, coal, and tobacco. They were actually large cartels.
By the 1880s, the government passed laws to protect competition. 28
Anti-trust legislation – designed to monitor and regulate big business,
prevent monopolies and break up existing monopolies.
1. Interstate Commerce Act-1887 – created the ICC to oversee railroad
rates. Today it regulates railroads, motor vehicles, & other freight carriers.
2. Sherman Anti-trust Act-1890 – the “cornerstone of anti-trust legislation.”
It prohibited any agreements, contracts or conspiracies that would
restrain interstate trade or cause monopolies to form. This act protected trade
against unlawful restraint & monopoly. It was the 1st significant act against
monopolies. Later legislation defines the principles in this act.
The Sherman Anti-trust’s failure to define key terms such as “trusts” and
“restraint of trade” made it somewhat ineffective. It was not clear what was
legal or illegal. This act also ran contrary to the economic theory of
laissez-faire (hands-off by the government) attitude of the past 100 years. 29 30
