1. When is EAC analysis appropriate for comparing two or more projects? Why is this method used? Are there any implicit assumptions required by this method that you find troubling? Explain.

The EAC approach is appropriate when comparing mutually exclusive projects with different lives that will be replaced when they wear out. This type of analysis is necessary so that the projects have a common life span over which they can be compared; in effect, each project is assumed to exist over an infinite horizon of N-year repeating projects. Assuming that this type of analysis is valid implies that the project cash flows remain the same forever, thus ignoring the possible effects of, among other things: (1) inflation, …show more content…

Using the present value of an annuity equation, we find: PV = C(PVIFA20%,10) $13,000,000,000 = C(PVIFA20%,10) C = $3,100,795,839

This is the total cash flow, so the number of planes that must be sold is the total cash flow divided by the cash flow per plane, or: Number of planes = $3,100,795,839 / $52,208,835 Number of planes = 59.39 or about 60 planes per year

5. Explain why a characteristic of an efficient market is that investments in that market have zero NPVs.

On average, the only return that is earned is the required return—investors buy assets with returns in excess of the required return (positive NPV), bidding up the price and thus causing the return to fall to the required return (zero NPV); investors sell assets with returns less than the required return (negative NPV), driving the price lower and thus causing the return to rise to the required return (zero NPV).

6. A stock has had returns of 3 percent, 38 percent, 21 percent, 15 percent, 29 percent, and 13 percent over the last six years. What are the arithmetic and geometric returns for the stock?

The arithmetic average return is the sum of the known returns divided by the number of returns, so: Arithmetic average return = (.03 + .38 + .21 – .15 + .29 – .13) / 6 Arithmetic average return = .1050 or 10.50%

Using the equation for the
