In determining where to invest your money, two objectives, expected rate of return and degree of risk, are considered to be equally important. Two investments (1 and 2) have the pairwise comparison matrices shown in the file P16_28.xlsx.
a. How would you rank these investments?
b. Now suppose another investment (investment 3) is available. The pairwise comparison matrices for these investments are also shown in this file. (Observe that the entries in the comparison matrices for investments 1 and 2 have not changed.) How would you now rank the investments? Contrast your ranking of investments 1 and 2 with your answer from part a.
