71) World Corporation has traditionally employed a firm-wide discount rate for capital
budgeting purposes. However, its two divisions, publishing and entertainment, have different
degrees of risk given by βP = 1.1, βE = 1.8, while the beta for the overall firm is 1.3. The
publishing division has proposed three projects with these internal rates of return: P1 = 13.2
percent; P2 = 12.4 percent; and P3 = 9.8 percent. The entertainment division has presented their
three projects: E1 = 16.4 percent; E2 = 17.8 percent; and E3 = 14.7 percent. The risk-free rate is
4 percent and the market risk premium is 8 percent. Identify which projects will be accepted if
the firm applies its overall beta to all projects. Then identify which projects will be accepted if
the division betas are properly applied.
72) On-line Text Co. has four new text publishing products that it is considering. The projects
are of equal risk with a beta of 1.6. The risk-free rate is 4.2 percent and the market rate is
expected to be 12.3 percent. The projects and their expected internal rates of return are: W = 14.4
percent; X = 18 percent, Y = 16.4 percent; and Z = 17.2 percent. Which projects should be
