5) A person with a current wealth of $100,000 who faces the prospect of 25 percent chance of losing his or her $20,000 automobile through theft during the next year. Suppose this person's utility function is U(Y) = InY. a). If this person takes no action, what is the expected utility? b). What is the actuarially fair premium? What is his expected utility if he purchase this insurance. This

5. Larry, who has wealth (w) of 100, faces a 25% probability that a catastrophe will eliminate all of his wealth. Larry's utility function is u(w) = In (w + 1). We will cover insurance on 12/2 in case you want to hold off on parts (b) and (d) until then. Characterize Larry's preference over risk. Is he risk-averse, risk-loving, or risk-neutral? а. Explain. b. What is the highest premium that Larry would accept for full insurance? C. Alternatively, suppose that Larry's utility is u (w) = e". Characterize his preference for risk and explain your answer. d. Under this alternative utility function, what is the highest premium that Larry would accept for full insurance? Explain.
The value of a successful project is $420,000; the probabilities of success are 1/2 with good supervision and 1/4 without. The manager is risk neutral, not risk averse as in the text, so his expected utility equals his expected income minus his disutility of effort. He can get other jobs paying $90,000, and his disutility for exerting the extra effort for good supervision on your project is $100,000. (a) Show that inducing high effort would require the firm to offer a compensation scheme with a negative base salary; that is, if the project fails, the manager pays the firm an amount stipulated in the scheme. (b) How might a negative base salary be implemented in reality? (c) Show that if a negative base salary is not feasible, then the firm does better to settle for the low-pay, low-effort situation.
Monty Burns, the owner of the Springfield Nuclear Power Plant, owns many real estate properties. His last acquisition is a house worth €1,000, 000. Monty Burns considers purchasing an insurance for this new property. With probability 0.1, he will face damage reducing his property' value to €640,000 while with probability 0.9 his property will not be damaged and thus will remain at its current value. Burns' vNM utility for wealth is given by u°(w) = Vw. Miss b runs an insurance company in Springfield and is willing to insure Monty Burns. The insurance contract says the following: if Burns' new property is damaged, she will pay an amount q (the coverage) to Monty Burns in exchange for a payment r (the premium) that is due independently from the occurence of the damage. Miss b's vNM utility over her income y is u°(y) = y.
2. Two individuals have the same income ($100,000), but different potential healthcare expenses. Person A's probability of having $80,000 in healthcare expenses is 0.5 percent. Person B's probability of having $800 in healthcare expenses is 50 percent. Assume your utility is U = VI where I is your income. Calculate each person's expected income and expected utility. Calculate each person's certainty equivalent. What does value of the certainty equivalent tell you about how much each person would be willing to insure against their loss?
Adam presently makes about $40,000 of interest income per year. He realizes that there is about a 5 percent probability that he may suffer a heart attack. The cost of treatment will be about $20,000 if a heart attack occurs. A. Calculate Adam's expected utility level without any health insurance coverage. B. Calculate Adam's expected income without any insurance coverage. C. Suppose Adam must pay a premium of $1,500 for health insurance coverage with BlueCross Blue Shields insurance. Would he buy the health insurance? Why or why not?
Then what of part d, e and f?
Exercise 4: Insurance Fiona has von Neumann-Morgenstern utility function u(x) = VT and initial wealth 640, 000. She faces a 25% chance of losing L = 280, 000. 1. Is Fiona risk averse? 2. What is Fiona's utility if no loss occurs, what is her utility if the loss occurs? What is Fiona's expected utility? 3. What is the cost of fair insurance against the possible loss? Suppose Fiona is able to choose insurance with any coverage z E [0, 1] (i.e. 0 0 C(z) = if z = 0 4. Suppose co = 0 and c1 = 70,000. Is insurance at coverage level z > 0 fair insurance? What coverage level z* would Fiona choose? Explain. 5. Suppose co = 100 and c1 = 70,000. Is insurance at coverage level z > 0 fair insurance? What coverage level z** would Fiona choose? Explain. (Note that co = 100 is an "avoidable fixed cost" which is only paid if she chooses strictly positive insurance coverage. However, the "marginal cost" of additional insurance, c1 = 70,000, is the same as in the previous part.) 6. Suppose co = 100 and…
2. Consider an individual with a current wealth of $100,000 who faces the prospect of a 25% chance of losing $20,000 through theft of her car during the next year. If the person’s utility function is U(X) = ln(X), where X is wealth: a. calculate expected utility without insurance, b. calculate the actuarially fair premium for full insurance, c. calculate expected utility with full insurance at the actuarially fair premium d. calculate the maximum amount the individual would pay for full insurance.
Exercise 5: Insurance Consider two individuals, Dave and Eva. Both Dave and Eva have initial wealth 810,000 and face a 40% chance of losing L = 450, 000. Dave has von Neumann-Morgenstern utility function up(x) = x and Eva has von Neumann-Morgenstern utility function ug (x) = VT. 1. What do you know about Dave's and Eva's risk preferences? 2. What is the most Dave would be willing to pay for complete insurance against the loss? 3. What is the most Eva would be willing to pay for complete insurance against the loss? Suppose they are each able choose insurance with any coverage level z [0, 1] (i.e. 0 0. 6. Is Eva's optimal choice full insurance, i.e. z = 1?
Priyanka has an income of £90,000 and is a von Neumann-Morgenstern expected utility maximiser with von Neumann-Morgenstern utility index . There is a 1 % probability that there is flooding damage at her house. The repair of the damage would cost £80,000 which would reduce the income to £10,000. a) Would Priyanka be willing to spend £500 to purchase an insurance policy that would fully insure her against this loss? Explain. b) What would be the highest price (premium) that she would be willing to pay for an insurance policy that fully insures her against the flooding damage?
