Each asset has a price of $50. The first asset is riskless and pays off $50 next period in each of the two possible states. The risky asset pays off zs in state s = 1, 2. Suppose also that the individual cares only about next period consumption (denoted by c1 or c2 depending on the state). The probability of state 1 is denoted by π. (a) If the individual splits his wealth equally between the two assets, fill in the following table assuming that each of three scenarios is considered. Scenario 1 2 3 (z1 , z2 ) (20,80) (38,98) (30,90) π 1/5 1/2 1/3 (c1 , c2 ) E[c] Var[c] (b) How would this individual rank these three scenarios? Explain and give reasons to support your argument. (c) Show that under each scenario the individual’s optimal decision is to invest an equal amount on each of the two assets. Problem 2. Consider an agent with a well-behaved utility function who must balance his portfolio between a riskless asset and a risky asset. The first asset, with price p1 has the certain payoff z1 while the second asset, with price p2 pays off z2 which is a random variable. The agent has an initial wealth Y0 and he only cares about next......
