Erin Chou is reviewing a profitable investment project that has a conventional cash flow pattern. If the cash flows for the project, initial outlay, and future after-tax cash flows all double, Chou would predict that IRR would: a. increase and the NPV would increase b. stay the same and the NPV would increase c. stay the same and the NPV would stay the same 没太懂为什么选b

An investment of $20000 will create a perpetual after-tax cash flow of $2000. The required rate of return is 8 percent. What is the investment's profitability index? A. 1.08 B. 1.16 C 1.25 这道题我看了答案解析，求pv时用的是2000/0.08 而不是2000/（1+0.08）是为什么呢？pv不是等于future cash flow/(1+r)^t，这里的分母为什么没有+1呢？

老师你好，原版书19页的example，选项B为什么对？B：some ethical behavior may be illegal.一些符合道德的行为可能不合法？不合法一定不道德吧？Civil disobedience is an example of what may be illegal behavior that some consider to be ethical.这句话是什么意思？

Why A to B is LIBOR not LIBOR+1%?
