If a patient has a probability of being sick of 0.1 and a probability of being healthy of 0.9. If the person has a good health her wealth will be $100, if she has bad health her wealth will be $64. Suppose that the utility of wealth come from the following utility function: U(W)=W^0.5.

The expected utility of the patient if she has no insurance is

Answer #1

Utility with bad health = 640.5 = 8

Utility with good health = 1000.5 = 10

Expected utility (no insurance) = Probability x Utility = 8 x 0.1 + 0.9 x 10 = 9.8

    A lab test produces a positive result with 90% probability when the patient is actually sick and with 10% if the patient is healthy. It is known that 15% of the population is sick. (a) What is the joint probability function of patients’ health and test results? (b) If the test is positive, what is the probability that the patient is actually sick? (c) The probability you just calculated in part 1b is the _____ probability of ____ given _____.

    An investor's utility function for money (Bernoulli utility function) is the square root of money: u(x)=√x. Her decision making can be modeled by assuming that she maximizes her expected utility. Her current wealth is 100. (All quantities are in hundreds of dollars.) She has the opportunity to buy a security that either pays 8 (the "good outcome") or loses 1 (the "bad outcome"). She can buy as many units as she wishes. For example, if she buys 5 units, she...

    A person with the following utility function, u(x) = ln(x) faces a world where with probability 0.1 will suffer of identity theft which will reduce their wealth from $250000 to $100000. This means that we can write: E{u(.)] = 0.91n(x) +0.1ln(y) where x would be the wealth under no identity theft and y the wealth under identity theft. This means that the marginal utilities are: MU 0.9, MUy = 0.1 Using this information answer the following questions 1) What is...

    2) (20 points) Lynn has a utility function U(W) = W1/2, where W is the amount of wealth that she has. Lynn has two assets. She has $40,000 in a bank account, and she has a house worth $600,000, so her total wealth is initially $640,000. There is a 2% chance that her house is destroyed by a fire. a) (4 points) Considering the probability that there is a fire, what is Lynn’s Expected Wealth, E(W)?

    i) Suppose that Mary’s utility function is where W is wealth. Is she risk averse? Suppose that Mary has initial wealth of $125,000. How much of a risk premium would she require to participate in a gamble that has a 50% probability of raising her wealth to $160,000 and a 50% probability of lowering her wealth to $90,000? ii) Suppose that Irma’s utility function with respect to wealth is U(W) = 100 + 80W − W2.

    Tom has an initial wealth of 100. His car may be stolen so he runs a risk of a loss of 40 dollars. The probability of loss is 0.2. It is possible, however, for Tom to buy insurance. One unit of insurance costs γ dollars and pays 1 dollar if the loss occurs. Thus, if α units of insurance are brought, the wealth of Tom will be 100-γα if there is no loss (a good state) and 100-γα-40+α if the...

    1. Suppose that an individual has a wealth of $50,000 and the utility of U(W) = VW. This individual has the option of investing all wealth in risky stock, which is worth $100 per share, which will be worth $105 per share in a good state with probability 1/2 and $95 per share in a bad state with probability 1/2. Assume, the interest rate is zero. (a) Find the expected value and the expected utility of investing all wealth in...

    Question 1 (20 marks) (a) A consumer maximizes utility and has Bernoulli utility function u(w)/2. The consumer has initial wealth w 1000 and faces two potential losses. With probability 0.1, the consumer loses S100, and with probability 0.2, the consumer loses $50. Assume that both losses cannot occur at the same time. What is the most this consumer would be willing to pay for full insurance against these losses? (10 marks) (b) A consumer has utility function u(z, y) In(x)...

    Cindy is an expected utility maximizing consumer who has an initial wealth of $160,000 and is subject to fire risk. There is a 5% chance of a major fire with a loss of $70,000 and a 5% chance of a disastrous fire with a loss of $120,000. Her utility function is U = W1/2. Cindy is offered an insurance policy costing $12,000 with a deductible provision, which requires that she pay the first $7,620 on any fire loss (that is,...
