I got a negative NPV. Is this what everyone else is getting?
[NEAS: In practice, the expected NPV of projects is zero. Firms have some projects with positive NPV's and some with negative NPV's. The final exam problems often have negative NPV's.]
The crux of the homework is distinguishing between nominal and real cash flows/discount rates.The cash flows given are nominal. Thus, we use the nominal discount rate and obtain a negative answer.
[NEAS: Correct]
