Examples
Perfect Competition
• Many buyers and many sellers
• The market is perfectly transparent
Perfect Competition
• All firms sell identical products.
Perfect Competition
• It’s easy to get into and out of the market.
Perfect Competition
• Sellers are price takers. They must sell
their product at the equilibrium price and
not one penny more
Perfect Competition
• A market may not satisfy one or more of
the four conditions and still be perfectly
competitive
• What determines whether a market is
perfectly competitive or not is if firms
(sellers) in the market are price takers.
Perfect Competition
• Wheat Market, Corn Market, Stock Market,
other agricultural markets
Critical Thinking
• Some of the 200 firms in Market X, a
perfectly competitive market, are incurring
losses. How will these losses influence….
– entrance/exit to the market?
– the supply of the good produced in the market?
– the price of the good?
Think of a flow chart….
• How can a seller determine whether or not
they are a price taker?
• Can he/she sell any of the product for
even one cent more than equilibrium
price?

MONOPOLY

• The product sold is UNIQUE – there are
no close substitutes

• Extremely high barriers to entry…it’s hard
to get into a monopoly market.
• Legal Barriers

• Extremely Low Per-Unit Costs
– a natural monopoly
• Exclusive ownership of an essential resource
Monopoly
• Monopolists are price searchers. They can
sell some of their product at various
prices.
• The demand curve will determine how
much they can sell and at what price.
• Price will be determined based upon their
decision on how much to produce.

Competitors and Monopoly
•
Many businesses would like to become a
monopoly
– they advertise perceived differences
•
Competition depends on two factors:
1. How close to unique the product is
2. How easy it is for sellers to enter the market
Oligopoly
•Name five American car
manufacturers
Oligopoly
• There are few sellers.
• A few sellers account for a large
percentage of sales
Oligopoly

differentiated products.

Identifying Oligopoly
Industries
Economist determine whether a market is an oligopoly by
looking at the percentage of sales accounted for by the top four
firms in the industry
– 6 major film studios = 90% of revenue
• 20th century, Warner Brothers, Paramount, Columbia, Universal, Walt Disney
• Dreamworks (Viacom bought—owned by Paramount)
– 2008 became independent again but distributed by Disney
• Leading Indies: Lionsgate, Summit Entertainment, MGM (former Biggie!)
– 4 music companies = 80% of revenue
• Sony, EMI, Universal, Warner
– 6 book publishers

Review
• Firm A is a perfectly competitive firm. Why
can’t it sell its product for one penny
higher than equilibrium price?
• Buyers would know that they could buy
that identical product for the cheaper price.
Why would they pay one penny more?
Review
• To become an attorney, a lawyer must
pass the bar examination. Is the bar
examination a barrier to entry in the law
market?
• Yes
Review
• Firms in a monopolistic competitive market
produce slightly differentiated products. How
might these products be differentiated?
• Besides differences in product, they could be
sold in different locations, by different people, in
a store, online or by phone. They can be
bundled with different services or sales
conditions.
Review
• How can profits be “competed away” in a
perfectly competitive market?
• It’s an easy market to enter. When
businesses see the high profits, they enter
the market. More supply lowers the
price…
Review
• What are the two major factors that decide
how much competition a firm faces?
• How close to unique is the product?
• How easy is it to get into the market for
this product?

“Stupid is as stupid does.”
As you watch the clip from “Forest Gump,” note the
process related to Bubba Gump Shrimp’s position in
the shrimping market.
1. Before the hurricane, how does the shrimping
industry resemble a perfectly competitive market?
2. How does the hurricane change the market price
and quantity of shrimp? (Use supply & demand
graphs to illustrate.)
3. How did the hurricane create a monopoly for Bubba
Gump Shrimp? Use the characteristics of a
monopoly to support your answer.
4. Do you think Forest can maintain his monopoly
status over time? (In other words, are there barriers
to entry?) Explain.
