The average price of gasoline in your neighborhood is $2.15 per gallon. Your neighbor,
Diana tells you that you can 'save a lot" by frequenting a gas station 20 miles outside
your neighborhood where the price of gasoline is $2.06 per gallon However, she
cautions you that there are usually long lines at that station. Is her suggestion beneficial
to you?
A) Yes, since gasoline is a necessity for car owners, the total cost savings would be
relatively substantial.
B) No, if one factors in the non-monetary opportunity costs (driving time and waiting in
line), it could prove more costly to go to the lower-priced gasoline station.
C) Yes, the lower price of gasoline at the rival station increases my purchasing power
and enables me to consume more of other goods.
D) No, my friend is misled; clearly, the lower-priced gasoline must be of inferior
quality and could damage vehicles.

Article Summary
In an attempt to get approval for a $6.3 billion merger with Office Depot, Staples met
with FTC regulators to discuss the possible sale of assets so the merger can proceed.
The Competition Bureau of the FTC had previously indicated that it would not approve
the merger as initially structured, but Staples expressed optimism that it would be able
to reach a settlement with the FTC. Critics have argued that a merger of Staples and
Office Depot will result in higher prices for office supplies.

October 14, 2015.
Refer to the Article Summary above. The standards used by the Department of Justice
and the FTC to evaluate a potential merger such as the one between Staples and Office
Depot are based on market concentration as determined by the
A) Herfindahl-Hirschman Index.
B) Clayton Antitrust Act.

Figure 14-4
Rainbow Writer (RW) is a small online company selling a highly rated software
package for engraving words onto objects produced by 3D printers. The firm currently
earns a profit of $2 million per year selling its package exclusively on its Website.
Odeon, the producer of the most popular 3D printers has expressed interest in bundling
Rainbow Writer's product with its printers. Odeon expects that bundling would further
boost its sales and allow it to sell its printers at a higher price, thus raising its profits
beyond its current profit of $12 million. Figure 14.4 shows the decision tree for the
Rainbow Writer-Odeon bargaining game.
Refer to Figure 14-4. What is the equilibrium outcome in this game and is this a
subgame-perfect equilibrium?
A) In the equilibrium, neither offer is accepted as Rainbow Writer holds out for a better
deal. The two rejection outcomes are subgame-perfect equilibria.
B) In the equilibrium, Odeon offers $40 per copy of the software package and is
accepted but this is not a subgame-perfect equilibrium.
C) Either offer of $30 or $40 per copy of the software package is accepted and these
two equilibria are subgame-perfect equilibria.
D) Either offer of $30 or $40 per copy of the software package is accepted but these are
not are subgame-perfect equilibria.
Juicy Couture has been successful in selling women's clothing using an unusual
strategy.
According to an article in the Wall Street Journal, the key to the firm's strategy is to

brands." In 2006, Juicy clothes were sold in only four department stores: Neiman
Marcus, Saks, Bloomingdale's, and Nordstrom. In 2006, its sales have more than
quadrupled since 2002.

products.
B) It enables Juicy to price its products at a premium and differentiate them from
lower-priced products.
C) It helps establish Juicy's products as luxury items favored by the very wealthy.
D) Maintaining the exclusivity of a product increases the demand for the product.
