You have saved $5,000.00 and decide to invest it. There are two types of investment you can choose. The first one is safe and guarantees you will earn $300.00 in one year. The second one is riskier: with probability 0.5, you could earn $4,000.00, but with probability 0.5 you might lose $4,000.00. If your utility for the money is v(m)=ln(m), which investment will you choose?
