15) Standard economic theory asserts that sunk costs are irrelevant in making economic
decisions, yet studies conducted by behavioral economists reveal that sunk costs often affect
economic decisions. Which of the following could explain this observation?
A) People measure the value of a good in terms of its purchase price.
B) Even though sunk costs cannot be recovered, it has been incurred and therefore should be
treated as part of the product’s value.
C) If consumers maximize their utility, it makes sense to consider the full purchase price of a
product in their consumption decisions.
D) Sunk costs have a higher opportunity cost than costs that can be recovered.
16) Many celebrities are paid to endorse products, but celebrity endorsements do come with
risks. Once a firm is associated with a celebrity, consumers associate the product with the
celebrity. This association can turn negative if the celebrity gets arrested or becomes associated
with an embarrassing scandal. Should a company whose celebrity endorser was just arrested be
guided by the amount it has already poured into making ads featuring the celebrity in its decision
about whether or not to cancel the ad campaign?
A) Yes, even in the case of negative publicity, celebrity endorsements really do have a
significant effect on consumer choice so the amount already spent to purchase this endorsement
is relevant.
B) No, the amount spent to launch the campaign is a sunk cost; the firm’s primary concern at this
point is the effect of the negative publicity on the product’s image.
C) Yes, a firm must take in all costs in deciding whether or not to yank the campaign. If the
revenue loss (due to the negative publicity) is small compared to the cost of the campaign, then it
makes sense to continue the campaign.
D) No, although the amount spent to launch the campaign cannot be recovered, the firm can still
reap some benefit by taking out another ad in support of the celebrity.
