The evidence is overwhelming that obesity generates demand for more joint replacements.O .A) This is an ex-post moral hazard problem, user fees will solve the problem.O. B) This is an ex-ante moral hazard problem, incentives for obesity reduction, such as subsidies for exercise, may alleviate the problem.O. C) This is cherry-picking by orthopaedic surgeons.O. D) Since this is adverse selection, the total cost of a public insurance system will not be affected.OE) This is an ex-post moral hazard problem, co-insurance will solve the problem.
Multiple Choice Adverse selection describes a situation where an individual's demand for insurance is positively correlated with the individual's risk of loss. Adverse selection occurs when someone increases their exposure to risk when insured. This can happen, for example, when a person takes more risks because someone else bears the cost of those risks. The relationship between smoking status and mortality provides a good illustration for adverse selection, especially in the case in which a life insurance company did not vary its premiums according to smoking status of its customers. To counter the effects of adverse selection, insurers may offer premiums that are proportional to a customer's risk.
Suppose the demand for anxiety medication prescriptions is given by P = 300 – Q. Suppose the marginal cost for a prescription of anxiety medicine is constant at $100 per prescription. a. What is the quantity demanded in the absence of any insurance coverage for anxiety medication? b. Now, suppose there is full insurance coverage for anxiety medication (i.e. no cost-sharing at all). What is the new quantity demanded? c. Finally, suppose insurance covers anxiety medication, but there is 20% coinsurance, meaning that individuals must pay 20% of the cost of anxiety medication out of pocket. What is the new quantity demanded? d. Under the insurance structure given in part (c), what is the deadweight loss associated with the presence of insurance coverage?

Provide an intuitive discussion of how adverse selection affects the used-car market. Describe one potential signal that can help alleviate the problem of adverse selection in this market and discuss how this signal satisfies the two necessary assumptions for it to be used as a credible signal.
Suppose there are two types of people, high risk (H) and low risk (L) with utility function U(c) = c0.5 Each has income (=consumption) of $100. The high risk people are 10% of the population and have a 75% chance of getting cancer in which case their income would be zero. The low risk people are the remainder of the population and have a 25% chance of getting cancer and hence zero income. The private insurance industry is perfectly competitive. Insurers are afraid the government will take over the industry and decide to price in a different way. Mindful of the social consequences they will price so that the high risk is fully insured. What condition must be placed on the low-risk for this to be an equilibrium? What is the expected utility of the low-risk given the condition?
Suppose in a given state's new insurance marketplace, with community rating and no restrictions on who can buy at the community rate, the risk pool (distribution of expected health costs) is as follows: 30% of eligible enrollees' expected health costs = $1,000 (per year)65% of eligible enrollees' expected health costs = $2,0005% of eligible enrollees' expected health costs = $10,000 Now suppose one insurer, and one insurer only, were allowed to offer any premium it wanted to any potential buyer and to exclude those it did not want to cover? What premium would they likely charge and who would they sell to and who would they exclude? What would happen to the other insurers? Does this help you see why the ACA was written to apply to all insurers?
18.5 Suppose there is a 50–50 chance that an individual with log- arithmic utility from wealth and with a current wealth of $20,000 will suffer a loss of $10,000 from a car accident. Insur- ance is competitively provided at actuarially fair rates. Compute the outcome if the individual buys full insurance. Compute the outcome if the individual buys only partial insurance covering half the loss. Show that the outcome in part (a) is preferred. Now suppose that individuals who buy the partial rather than the full insurance policy take more care when driv- ing, reducing the damage from loss from $10,000 to $7,000. What would be the actuarially fair price of the partial policy? Does the individual now prefer the full or the partial policy?
Use the following information for questions 12-14. Assume that there are two parties, I and V. I engages in an activity that tends to injure V. V and I both can take care to reduce the expected harm from accidents. Specifically, suppose that if I takes no care (i.e., spends $0 on accident precautions), expected injury to V is $25. If I spends $5 on accident precautions, however, the expected injury to V is reduced to $18. Further suppose that V has a choice between taking no care or spending $4 in care to avoid accidents. If V spends $4 in care, V’s expected harm falls by $2 regardless of the level of care that I takes. Assume that courts adopt the socially-optimal level of injurer care as the negligence standard. That is, if I takes less than the socially-optimal level of care, she will be found negligent and must pay for all damages toV. If I takes at least the socially optimal level of care, she will not have to compensate V for his damages. Under a negligence standard, what is…

Faustian health economics. Consider Figure 11.10, which shows the locus of feasible contracts for the population of the nation of Pcoria. In which corner of this diagram (northeast, southeast, northwest, or southwest) is utility highest for consumers? What prevents insurance companies from offering contracts in this corner? On your own version of Figure 11.10, plot new points to represent where the market would be under (i) a nationally mandated full insurance policy and (ii) an insurance ban. (Please draw a diagram) Would a nationally mandated full insurance policy be optimal for Pcoria? What about an insurance ban? Suppose the devil approaches the newly elected president of Pcoria with an unusual bargain. He offers to magically eliminate moral hazard, but in return, Pcoria must forbid contracts that are more than half full. On a new version of Figure 11.10, draw a new locus of the contracts that would be feasible if the president takes the devil's bargain. Should the president take…
