Investment 3. Investment 4. C is correct. Investment 4 provis the highest utility value (0.2700) for a risk-seeking investor, who ha measure of risk aversion equto −2. 这道题第四个,应该是18+0.09,而不是27+…吧?
第四个组合U=18+0.5*2*0.3^2=18.09 第三个组合U=20+0.5*2*0.15^2=20.0225 选第三个组合才对吧?
4 hthe biggest stanrviation & biggest uyility,所以选4? 如果4 hthe biggest stanrviation & samaller uyility,那选谁? 除了risk neutral选择最大的return之外,risk seeker 和risk averse都选择最大的utility?
risk-seeking investor和risk averse investor 都要选择utility最大的组合吗?
