2. Investors can choose to purchase either a risky portfolio or a riskless bond. The bond costs $95 today and will be worth $100 at the end of the year. The risky portfolio costs $580 today. If the economy does well, which occurs with probability 0.3, the risky portfolio will be worth $720 at the end of the year. If the economy just treads water, which occurs with probability 0.5, the risky portfolio will be worth $600 at the end of the year. If the economy does poorly, which occurs with probability 0.2, the risky portfolio will be worth $520 at the end of the year. What is the market price of risk in this scenario?
