Economists David Laibson and Xavier Gabaix examined the behavior of consumers when buying
products that consist of a "base good" and "add-ons." Firms typically compete on the price of the
base good (for example, a printer) rather than an add-on (for example, ink cartridges). They found
that firms are often successful in hiding the prices of add-ons from consumers. What explanation
do Laibson and Gabaix offer for why some firms do not offer lower-priced add-ons and advertise
the higher prices of rival firms?
127)
A)
Firms fear that competition for add-ons would force them to also lower the prices of their
base goods.
B)
Firms fear that an ad campaign could lead to competition that would force all firms to lower
the prices of their add-ons.
C)
The demand for add-ons is very inelastic. Lowering the price of add-ons would reduce total
revenue.
D)
Using advertising to inform consumers who typically ignore the price of ad-ons is not a
profitable strategy.
128)
The income effect of an increase in the price of salmon
128)
A)
is the change in the demand for other types of fish that results from a decrease in purchasing
power.
B)
refers to the effect on consumer purchasing power which causes the consumer to buy less
salmon, holding all other factors constant.
C)
is the change in the demand for salmon when income increases.
D)
refers to relative price effect - salmon is more expensive compared to other types of fish -
which causes consumers to buy less salmon.

An article in the Wall Street Journal noted the following: Instead of relying on a full-coach,
round-trip unrestricted fare of about $2,000 between Cleveland and Los Angeles ...Continental
[Airlines] since June has offered a $716 unrestricted fare in that market .... Through October, the test
resulted in about the same revenue that Continental thinks it would have collected with its higher
fare.

According to an article in the Wall Street Journal, unlike airlines, even elite hotels don't have
sophisticated systems that can react quickly to changes in demand. Even if they could, many
hoteliers say people don't respond that much to lower rates. "We've tested this, cutting our rates by
$50 [per night], and we didn't see an appreciable response in occupancy," says Jim Schultenover, a
vice president for Ritz-Carlton.

Based on the information above, the demand for hotel rooms
133)
A)

Table 6-4
The publisher of a magazine gives his staff the following information:
Current price $2.00 per issue
Current sales 150,000 copies per month
Current revenue $300,000 per month
Current total costs $450,000 per month
He tells the staff, "Our costs are currently $150,000 more than our revenues each month. I propose to eliminate this problem
by raising the price of the magazine to $3.00 per issue. This will result in our revenue being exactly equal to our cost."
134)
Refer to Table 6-4. Which of the following statements is correct?
134)
A)
The publisher's analysis is correct only if the demand is perfectly elastic.
B)
The publisher's analysis is correct only if the demand is inelastic.
C)
The publisher's analysis is correct only if the demand is elastic.
D)

Suppose the price of gasoline in July 2004 averaged $1.35 a gallon and 15 million gallons a
day were sold. In October 2004, the price averaged $2.15 a gallon and 14 million gallons
were sold. If the demand for gasoline did not shift between these two months, use the
midpoint formula to calculate the price elasticity of demand. Indicate whether demand
was elastic or inelastic.

If the market for a product is narrowly defined, then there are likely to be many substitutes for the

ESSAY. Write your answer in the space provided or on a separate sheet of paper.
156)
Behavioral economists examine choices that consumers make that are not economically rational. Economists
generally assume that people are rational; that is, they weigh the benefits and costs of an action and choose an
action only if the benefits outweigh the costs. Why do consumers not act rationally when the result is that they
make themselves worse off?

A construction project in Congressman Foghorn's district is unfinished. Foghorn has asked that a new
appropriations bill include funds to complete the project, despite a report by an independent agency that the
project is a waste of taxpayer money. Foghorn's project is a bridge that crosses a river between two cities in his
district. The press has criticized Foghorn and dubbed the project "a bridge too far" since another bridge, located
closer to the same two cities Foghorn's bridge will connect, already exists and can accommodate all traffic
between the two cities. Foghorn argues that if the bridge project is not completed, the $50 million already spent
will have been wasted. Is Foghorn's argument economically rational? Explain your answer.
