QUESTION 3
Matt has inherited a large sum of money wo and is deciding how much to invest in a low interest savings
account with fixed rate of return rf
0.1 and how much to invest in his friend's new business, which is a
risky asset with random rate of return ã given by
S-0.6 with prob. 7 = 0.4
with prob. 1 – T = 0.6
0.9
Suppose Matt inherited wo
:8000 to invest and has a utility function over final portfolio value v given by
u(v) = v0.6.
(a) Calculate the optimal amount a* for Matt to invest in the risky asset.
(b) Now suppose that wo
20000 instead. Calculate the new optimal investment in the risky asset and
compare to your answer in part (a). Is there a shortcut way to quickly determine, based on (a), how much
Matt would invest in the risky asset when his wealth is higher?
