Consider the Consumption and Savings model with random future income. The utility function of the individual is: u(C0, C1) = (C0) + (C1)1/2, where C0 is present consumption expenditure and C1 is future consumption. Let the present income be $5, the interest rate in the financial market r = 5%, and the probability distribution of future income Y1 = (1, 2; 1/2 , 1/2). Calculate the expected utility of saving $0 (consume $5 in the present) (use two decimals)

Calculate the expected utility of John when he faces the risky prospect X = {1, 2, 3, 4; 0.2, 0.4, 0.4, 0.2} . His utility function is u(x) = 4 ln x, where x is wealth and ln represents the natural log. (Use two decimals)
Studies have concluded that a college degree is a very good investment. Suppose that a college graduate earns about 75% more money per hour than a high-school graduate. If the lifetime earnings of a high-school graduate average $1,200,000, what is the expected value of earning a college degree?
Suppose your utility function for money is a square-root function of its value in US dollars. So, for instance, $400 is worth 20 utils for you, $961 is worth 31 utils for you, and $62.5K is worth 250 utils for you. Now, let’s say your annual salary is $90K, although there is a small risk (p = 0.05) that something catastrophic will happen and reduce your income for the year to $14.4K. An insurance company comes along and offers to insure you against the loss of your salary. The cost of the insurance is $4,736. If you buy the policy and catastrophe strikes, the insurance company will pay out the $75,600 that you would otherwise have lost. From the standpoint of maximizing expected utility, would buying this insurance be a good deal for you? What would be the insurance company’s expected monetary value of selling you the policy?
The von-Neumann Morgenstern utility function is of the form u(e) - In(e). There is a lottery over consumption outcomes: with probability 0.3, the consumption will be 1 and with probability 0.7 the consumption will be 3; Compute the risk premium (round to 2 decimals).
An individual’s utility function is given as U (X) = X 0.5 where X represents the money, he has available for spending in a given time period. This individual has income of $225 in each time period and he discounts the future at the rate of 0.7. If he invests his up-front cost is 25 and his return in in the next time period is 35. a. Would this individual consider investing if his investment is financed by borrowing and cost of borrowing is 30%? (Consider two period model to justify your answer) b. Would this individual consider investing if his investment is financed by current savings? (Use two period model to justify your answer). c. Would this individual consider investing if his investment is financed by: $10 from current savings and rest of it from borrowing and the cost of borrowing is 30%? (Use two period model to justify your answer).

You are a risk-averse investor with a CRRA utility function. You are faced with the decision to invest your total wealth W of £1,000,000 into a riskless asset which generates a return of 5% or into a risky asset which either generates a return of 20% or a loss of −4% with equal probability. Find the optimal investment allocation with a coefficient of relative risk aversion η=2, and comment on your results.
