Consider the following portfolio choice problem. The investor has initial wealth w and utility u(x) = −e−x. There is a safe asset (such as a US government bond) that has net real return of zero. There is also a risky asset with a random net return that has only two possible returns, R1 with probability 1 − q and R0 with probability q. We assume R1 < 0, R0 > 0. Let α be the share of wealth w invested in the risky asset, so that 1−α share of wealth is invested in the safe asset.
(a) Find α as a function of w. How does α change with wealth? Explain the intuition. [15 marks]
please do not copy and paste a generic answer. Answer the question properly please and i will be sure to leave a thumbs up. thanks
