You have 1 dollar of initial wealth and would like to invest in some assets to consume tomorrow. In addition, you have the following utility function from consumption tomorrow, U(Y1)=ln(Y1).
- Assume that you have only two assets to choose from, a risky one and risk-free one. The probability of the High state is π, the net return on the risk-free asset is rf and the risky asset has a net return of rH in the High state and rL in the Low state. Find the optimal amount of dollars a you would invest in the risky asset. Provide derivations (8 points)
- How does the sign of the optimal amount of dollars invested in the risky asset depend on the expected returns of the risky and risk free assets? Why? (6 points)
- Does the optimal amount of dollars invested in the risky asset depend on the initial wealth? (3 points)
- Does the optimal share of the risky asset in your portfolio allocation depend on the wealth? Can you justify your finding? (3 points)
- Using the result in 1, plot the optimal amount of dollars invested in the risky asset as a function of the probability of High state for two cases: when the investor chooses only between asset A and B, and when she chooses between A and C. You can use Excel. (6 points)
- Compare the optimal allocation towards asset B and C from question 5 and explain the differences. (4 points)
