Consider the following portfolio choice problem. The investor has initial wealth w and utility u(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 Ro with probability q. We assume R₁ <0, Ro > 0. Let A be the amount invested in the risky asset, so that w - A is invested in the safe asset.
