4. An individual's Bernoulli utility function is u(w) = √w, and the individual has initial wealth 100. The individual might develop a health problem, which would reduce his or her wealth to 0. The individual might be "healthy" or "unhealthy." A healthy person develops the health problem with probability q = 0.3, while an unhealthy person develops the health problem with probability qH = 0.7. The probability that the individual in question is healthy is 1/2. An individual knows whether he or she is healthy, but an insurer does not. Without insurance, a healthy person's wealth is 100 with probability 0.7 and 0 with probability 0.3. Without insurance, an unhealthy person's wealth is 100 with probability 0.3 and 0 with probability 0.7. Insurers only offer "full insurance." That is, if the adverse event occurs, they will pay back 100, restoring the individual's full wealth. Insurers set a price for this policy Thonofor

- An individual has the utility function U(I) = I^(1/2), where I is their net income. (Note that I to the exponent/power of 1/2 is the same as the square root of I.) The individual starts with $1600 in income. The individual has a 20% probability of being very sick, 30% probability of being slightly sick, and 50% probability of being healthy. If the individual is sick, they lose net income because they need to pay healthcare costs. The healthcare costs are $1600 if they are very sick, $700 if they are slightly sick, and $0 if they are healthy. Please use this information for the following parts of this question unless otherwise specified. What is the individual's expected utility? Suppose a health insurance company offers the individual a full insurance contract. What is the actuarially fair, full insurance premium for this individual? What is the individual's expected utility if they purchase a full insurance contract at the actuarially fair, full insurance premium?An individual has 40,000 in income per year.

If the consumer goes to the gym, the probability of getting sick is 20%; if she does not go to the gym, the probability of getting sick is 80%. When sick, the consumer must go to the doctor. An insurance company is offering a health insurance plan with an insurance premium of $230 and a co-pay of $110 (that is, the consumer must pay the $110 if she goes to the doctor). a) The consumer's expected utility from purchasing this insurance and going to the gym is b) The consumer's expected utility from purchasing this insurance and not going to the gym is c) In this market, the $110 copay ✓ QUESTION 6 A salesperson is trying to sell ca Given her effort e, with probabili The dealership pays her a bonu a) Given the bonus b, the salesp b) Suppose the dealership pays *Select Answer* 34.6061 35.7999 37.0135 43.0338 42.4303 46.2601 fixes the adverse…

Explain why.Gary likes to gamble. Donna offers to bet him $31 on the outcome of a boat race. If Gary's boat wins, Donna would give him $31. If Gary's boat does not win, Gary would give her $31. Gary's utility function is p1x^21+p2x^22, where P₁ and p2 are the probabilities of events 1 and 2 and where x₁ and x₂ are his wealth if events 1 and 2 occur respectively. Gary's total wealth is currently only $80 and he believes that the probability that he will win the race is 0.3. Which of the following is correct? (please submit the number corresponding to the correct answer). 1. Taking the bet would reduce his expected utility. 2. Taking the bet would leave his expected utility unchanged. 3. Taking the bet would increase his expected utility. 4. There is not enough information to determine whether taking the bet would increase or decrease his expected utility. 5. The information given in the problem is self-contradictory.

- Y5 Alfred is a risk-averse person with $100 in monetary wealth and owns a house worth $300, for total wealth of $400. The probability that his house is destroyed by fire (equivalent to a loss of $300) is pne = 0.5. If he exerts an effort level e = 0.3 to keep his house safe, the probability falls to pe = 0.2. His utility function is: U = w0.5 – e where e is effort level exerted (zero in the case of no effort and 0.3 in the case of effort).a. In the absence of insurance, does Alfred exert effort to lower the probability of fire?HINT: Calculate and compare the expected utility i) with effort, and ii) without effort. If effort is exerted, then the effort cost is paid regardless of whether or not a fire occurs.b. Alfred is considering buying fire insurance. The insurance agent explains that a home owner’s insurance policy would require paying a premium α and would repay the value of the house in the event of fire, minus a deductible “D”. [A deductible is an amount of money that the…Question 4 Suppose that there is a 10% chance Ja'Marr is sick and earns $10,000, and a 90% chance he is healthy and will earn $70,000.

However, she takes a job as a worker in a firm that produces shirts. She and her coworkers are monitored at random by their employer to see if they are exerting a target level of effort of e* = 15 units. Assume that the probability of any worker being monitored is p. Also assume that e* is the same level of effort the worker would have to exert as a bank teller. If she is monitored and her employer finds that she is exerting at least 15 units of effort, she is paid > $100. If she is caught putting in less than 15 units of effort, she is fired on the spot but given severance pay of w < w. Say that she suffers a disutility of effort of $2, in monetary terms, for every unit of effort she exerts, so that the dollar cost of exerting the target level of effort of e* is - 2e*. (If she chooses to exert a lower level of effort than e*, we can assume that she will not…
