6-5. Bill Clinton reportedly
was paid $10 million to write his book My Way. The book took three years
to write. In the time he spent writing, Clinton
could have been paid to make speeches. Given his popularity, assume that he

of writing. Assume his cost of capital is 10% per year.

own a coal mining company and are considering opening a new mine. The mine
itself will cost $120 million to open. If this money is spent immediately, the
mine will generate $20 million for the next 10 years. After that, the coal will
run out and the site must be cleaned and maintained at environmental standards.
The cleaning and maintenance are expected to cost $2 million per year in
perpetuity. What does the IRR rule say about whether you should accept this
opportunity? If the cost of capital is 8%, what does the NPV rule say?

maintenance a good decision?
6-16. You are considering
investing in a new gold mine in South
Africa. Gold in South Africa is buried very deep,
so the mine will require an initial investment of $250 million. Once this
investment is made, the mine is expected to produce revenues of $30 million per
year for the next 20 years. It will cost $10 million per year to operate the
mine. After 20 years, the gold will be depleted. The mine must then be
stabilized on an ongoing basis, which will cost $5 million per year in
perpetuity. Calculate the IRR of this investment. (Hint: Plot the NPV as
a function of the discount rate.)

6-18. You are considering
constructing a new plant in a remote wilderness area to process the ore from a
planned mining operation. You anticipate that the plant will take a year to
build and cost $100 million upfront. Once built, it will generate cash flows of
$15 million at the end of every year over the life of the plant. The plant will
be useless 20 years after its completion once the mine runs out of ore. At that
point you expect to pay $200 million to shut the plant down and restore the
area to its pristine state. Using a cost of capital of 12%,
