16) Table 22-2
Three longtime friends-Allen, Brian, and Cody-are deciding how they will spend their
Sunday afternoon. They all agree that they should do one of three things: go to a movie,
play golf, or go to a baseball game. They also agree that they will have two pairwise
votes to determine how to spend their afternoon, with the majority determining the
outcome on each vote. The first, second, and third choices for each person are as
indicated in the table below.
Refer to Table 22-2. Which of the following statements is correct?
a.In a pairwise election, "movie" beats "golf."
b.In a pairwise election, "golf" beats "baseball game."
c.In a pairwise election, "baseball game" beats "movie."
d.None of the above is correct.
17) Scenario 16-7
Consider the problem facing two firms, YumYum and Bertollini, in the frozen food
market. Each firm has just come up with an idea for a new "frozen meal for two"which
it would sell for $9. Assume that the marginal cost for each new product is a constant
$2, and the only fixed cost is for advertising. Each company knows that if it spends $12
million on advertising it will get 1.5 million consumers to try its new product. YumYum
has done market research which suggests that its product does not have any 'staying"
power in the market. Even though it could get 1.5 million consumers to buy the product
once, it is unlikely that they will continue to buy the product in the future. Bertollini's
market research suggests that its product is very good, and consumers who try the
product will continue to be consumers over the ensuing year. On the basis of its market
research, Bertollini estimates that its initial 1.5 million customers will buy one unit of
the product each month in the coming year, for a total of 18 million units.
Which of the following is most likely?
a.Both YumYum and Bertollini will advertise.
b.Neither YumYum nor Bertollini will advertise.
c.YumYum will advertise, but Bertollini will not advertise.
d.Bertollini will advertise, but YumYum will not advertise.
