A risk-averse expected-utility maximizer has initial wealth w and utility function u. She faces a risk of a financial loss of L dollars, which occurs with probability π. An insurance company offers to sell a policy that costs p dollars per dollar of coverage (per dollar paid back in the event of a loss). Denote by x the number of dollars of coverage. (a) [5 marks] Give the formula for her expected utility V (x) as a function of x. (b) [10 marks] Suppose that u(z) = e −zλ , π = 1/4, L = 100 and p = 1/3. Write V (x) using these values. There should be three variables, x, λ and w. Find the optimal value of x, as a function of λ and w, by solving the first-order condition (set the derivative of the expected utility with respect to x equal to zero). (The second-order condition for this problem holds but you do not need to check it.) Does the optimal amount of coverage increase or decrease in λ? (c) [10 marks] Repeat exercise (b), but with p = 1/6. (d) [7 marks] You should find that for either (b) or (c), the optimal coverage is increasing in λ, and that in the other case it is decreasing in λ. Reconcile these two results.

A​‌‍‍‍‌‍‍‌‍‌‌‌‍‍‌‍‍‌‌‍​ clinic decides to adopt an EHR system. The CIO must decide whether to purchase the entire system or do a pilot project first. If the office implements the entire system, the net benefits are $200,000 (good), $50,000 (mediocre) or -300,000 (bad). The net benefits of the system to the office depends on whether the system works good, mediocre or bad. The probabilities of being good, mediocre or bad are 0.3, 0.6 and 0.1 respectively.
