a. An externality is a situation where a project would have an adverse effect on some other part of the firm’s overall
operations. If the project would have a favorable effect on other operations, then this is not an externality.
b. An example of an externality is a situation where a bank opens a new office, and that new office causes deposits
in the bank’s other offices to increase.
c. The NPV method automatically deals correctly with externalities, even if the externalities are not specifically
identified, but the IRR method does not. This is another reason to favor the NPV.
d. Both the NPV and IRR methods deal correctly with externalities, even if the externalities are not specifically
identified. However, the payback method does not.
e. Identifying an externality can never lead to an increase in the calculated NPV.
32. Which of the following statements is CORRECT?
a. If a firm is found guilty of cannibalization in a court of law, then it is judged to have taken unfair advantage of its
competitors. Thus, cannibalization is dealt with by society through the antitrust laws.
b. If a firm is found guilty of cannibalization in a court of law, then it is judged to have taken unfair advantage of its
customers. Thus, cannibalization is dealt with by society through the antitrust laws.
c. If cannibalization exists, then the cash flows associated with the project must be increased to offset these effects.
Otherwise, the calculated NPV will be biased downward.
d. If cannibalization is determined to exist, then this means that the calculated NPV if cannibalization is considered
will be higher than the NPV if this effect is not recognized.
e. Cannibalization, as described in the text, is a type of externality that is not against the law, and any harm it causes
is done to the firm itself.
