5. Investor attitudes toward risk Suppose an investor, Erik, is offered the investment opportunities described in the table below. Each investment costs $1,000 today and provides a payoff, also described below, one year from now. Option Payoff One Year from Now 1 100% chance of receiving $1,100 2 50% chance of receiving $1,000; 50% chance of receiving $1,200 3 50% chance of receiving $200; 50% chance of receiving $2,000 If Erik is risk averse, which investment will he prefer? The investor will choose option 1. The investor will choose option 2. The investor will choose option 3. The investor will be indifferent toward these options. Suppose the market risk premium is currently 6%. If investors were to become more risk-averse, the market risk premium might increase to 8%. What effect would you expect this to have on the prices of most financial assets? Prices would be unaffected. Prices would decrease. Prices would increase.
A risk-averse investor will: a. Always accept a greater risk with a greater expected return b. Only invest in assets providing certain returns c. Sometimes accept a lower expected return if it means less ri d. Never accept lower risk if it means accepting a lower expected return
Q1) An expected utility maximiser owns a car worth £60000£60000 and has a bank account with £20000£20000. The money in the bank is safe, but there is a 50%50% probability that the car will be stolen. The utility of wealth for the agent is u(y)=ln(y)u(y)=ln⁡(y) and they have no other assets. Q2) Consider the setup from Question 1. A risk-neutral insurance company is willing to insure the car at the premium of π=£2/3π=£2/3 for every one pound of coverage. Q3) Consider the setup from Questions 1 and 2. How much profits, in expectation, does the insurance company earn on insuring the individual?
