ndicate whether the statement is true or false, and justify your answer. 1. If physicians are earning monopoly rents, then there must be more barriers to entry in the labor market for physicians than is socially optimal. 2. In the model of insurance and uncertainty discussed in this course, an individual exhibits declining marginal utility of income if and only if she is risk averse. 3. Risk-averse consumers always prefer insurance that is actuarially fair but not full to full insurance that is actuarially unfair - but the opposite is true for risk-loving consumers.

This question is broken into 4 parts. Please answer all parts. A. Explain the relation between moral hazard and insurance premiums. B. Now think about how people with different health risks assess insurance products with a given deductible, and explain how supporters of minimizing adverse selection should think about a proposal (say from Bernie Sanders) that all insurance policies should have zero deductibles and coinsurance. C. Does community rating make the policy tradeoffs inherent in b harder or easier to manage? D. Would a purchase mandate make the policy tradeoffs inherent in b + c harder or easier to manage?
Consider an individual whose utility function over income I is U(I), where U is increasing smoothly in I (U’ > 0) and convex (U” > 0). Draw a utility function in U - I space that fits this description. Explain the connection between U” and risk aversion. True or false: this individual prefers no insurance to an actuarially fair, full contract. Be sure to explain your answer.
Which of the following statements is FALSE regarding the concept of "adverse selection"? 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.
Indicate whether the statement is true or false, and justify your answer.When insurance is fair, in a sense, it is also free.
Suppose that left-handed people are more prone to injury than right-handed people. Lefties have an 80 percent chance of suffering an injury leading to a $1,000 loss (in terms of medical expenses and the monetary equivalent of pain and suffering) but righties have only a 20 percent chance of suffering such an injury. The population contains equal numbers of lefties and righties. Individuals all have logarithmic utility-of-wealth functions and initial wealth of $10,000. Assume perfectly competitive insurance market and find (i) the first best and (ii) the second-best contracts.
Nathan's income in a typical year is 75,000. There is a 10 percent chance that Nathan will be seriously ill next year, incurring 15,000 in medical expenses. Samantha also earns 75,000 in a typical year. Her chance of becoming seriously ill next year and incurring ur 15,000 in medical expenses is 20 percent. a. Calculate the actuarially fair premium for full insurance for (i) Nathan and (ii) Samantha. b. Suppose that a private insurance firm cannot distinguish between Nathan and Samantha in terms of their risk and assumes the risk of being seriously ill in the general population is 10%. In this context, discuss the adverse selection problem the firm might face. c. Can a compulsory, government - run health insurance program avoid the problem of adverse selection? Explain why or why not.
Suppose, if ill, that Fred’s demand for health services is summarized by the demand curve Q = 50 − 2P , where P is the price of services. How many services does he buy at a price of $20? Suppose that Fred’s probability of illness is 0.25. What is the actuarially fair price of health insurance for Fred with a zero coinsurance rate? If the insurance company pays Fred’s entire loss, will the insurance company offer him insurance at the actuarially fair rate? Why? Note:- Do not provide handwritten solution.
