Amy’s utility function is U = √ C, where C is consumption and is given by C = Income − Expenses. Amy’s income is $10,000 and there is a 5% chance that she will get sick, which would cost $3,600 in medical expenses.
(a) (5 points) What is Amy’s expected utility if she doesn’t have insurance?
(b) (5 points) What is the actuarially fair premium for a full-coverage insurance plan? What is the actuarially fair premium for an insurance plan that provides 50% coverage?
(c) (5 points) What is the maximum premium that Amy would be willing to pay for a full-coverage insurance plan?
(d) (5 points) Suppose now there’s a government mandate: everyone must either buy full-coverage health insurance at a premium of $200, or pay a fine of $150 and stay uninsured. Would Amy purchase the health insurance or not?
