7) 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.
If YumYum decides to advertise its product it can expect to
a.incur a loss of $15 million.
b.incur a loss of $1.5 million.
c.earn a profit of $1.5 million.
d.earn a profit of $13.5 million.
