- Let U(x)= x^(beta/2) denote an agent's utility function, where Beta > 0 is a parameter that defines the agent's attitude towards risk. Consider a gamble that pays a prize X = 10 with probability 0.2, a price X = 50 with probability 0.4 and a price X = 100 with probability 0.4. Compute the agentís expected utility for such gamble and find the value of Beta such that the agentis risk neutral? Suppose B= 1, what is the certainty equivalent of the gamble described above? What is the Arrow-Pratt measure of absolute risk aversion?Consider the following utility functions: U1(x) = e*; U2(x) = x°, where r > 0 and BE (0,1); U3(x) = 2x + 10. For each function decide whether it belongs to a risk- neutral, risk-averse or risk-loving decision-maker.In the field of financial management, it has been observed that there is a trade-off between the rate of return that one earns on investments and the amount of risk that one must bear to earn that return. a) Draw a set of indifference curves between risk and return for a person that is risk-averse (a person that does not like risk).
- Natasha has utility function u(I) = (10*I)0.5, where I is her annual income (in thousands). (a) Is she a risk loving, risk averse or risk neutral individual? She is [risk loving, risk adverse, risk neutral] , as her utility function is [concave, convex, linear] (b) Suppose that she is currently earning an income of $40,000 (I = 40) and can earn that income next year with certainty. She is offered a chance to take a new job that offers a 0.6 probability of earning $44,000 and a 0.4 probability of earning $33,000. She should [take, not take] the new job because her expected utility of (approximately) [18.27,19.82,20,20.95,21.14] is [greater than, less than, equal to] her current utility of [18.27,19.85,20,20.95,21.14] .If the utility function is U (W) = ((W0.75) / (0.75)), what is the absolute risk aversion coefficient?3. Let us consider a utility function: U(x) = (V2x -1. (200sxs800) We have LiL2 where L1=(1, Y) and L2=(0.3, 450, 0.7,648). a. Determine the value of Y. b. Determine RP (Risk Premium) of L2.
- Consider the lottery that assigns a probability r of obtaining a level of consumption CH and a probability 1-T of obtaining a low level of consumption cL an individual facing such a lottery with utility function u(c) that has the properties that more is better (that is, a strictly positive marginal utility of consumption at all levels of c) and diminishing marginal utility of consumption, u"(c) CL. Consider du(c) for the first derivative of the utility function with respect to dc d²u(c) dc2 du' (c) consumption and u"(c) which is also the derivative of the first derivative of the utility function). to be the second derivative of the utility function dcSuppose that Bill's utility function of wealth is given by u(w) = √w, where w represents his total wealth in dollars. Bill's total wealth is $360,000. If an earthquake happens, his wealth will be reduced to $250,000 with the loss of his house. Suppose the probability of an earthquake happening is 10%. (a) Is Bill risk-averse, risk-loving, or risk-neutral? Explain. (b) If Bill could buy insurance to completely avoid the loss, how much would he be willing to pay for this insurance at most? Explain.Consider a household that possesses $200,000 worth of valuables such as jewelry. This household faces a 0.02 probability of a burglary, where she would lose jewelry worth $70,000. Suppose it can buy an insurance policy for $15,000 that would fully reimburse the $70,000. The household's utility function is U(X) = 4X⁰.5 Should the household buy this insurance policy? The household should not buy this policy. What is the actuarially fair price for the insurance policy? If the insurance is fair, then the cost of the insurance policy is $ 1400. (Enter your response rounded to two decimal places.) What is the most the household is willing to pay for an insurance policy that fully covers it against loss? The most the household would pay for such a policy (p) is S (Enter your response rounded to two decimal places.)
- Leora has a monthly income of $20,736. Unfortunately, there is a chance that she will have an accident that will result in costs of $10,736. Thus leaving her an income of only $10,000. The probability of an accident is 0.5. Finally assume that her preferences over income can be represented by the utility function u(x) = 2ln(x).a) What is the expected income? What is Leora’s expected utility (you may leave in log form)? b) What is the certainty equivalent to her situation? What is the risk premium associated with her situation?c) What is the maximum that Leora would be willing to pay for a full insurance policy?d) Illustrate her expected utility, expected wealth, certainty equivalent, the risk premium and her willingness to pay for a full insurance policy in a diagram.Consider an agent with the following utility function: %3D where o ("sigma") is a parameter that we fix and does not vary. (a) For which values of o is the agent risk averse? (hint: use the mathematical definition of risk aversion) (b) Compute the coefficient of absolute risk aversion and relative risk aversion. How do they vary with x? Consider the case where o = 2 and the lottery L that pays $ 3, $ 5 and $ 10 with equal probability. The agent has an initial wealth of $ 6. In order to participate to this lottery, the agent has to pay an amount of dollars p. (c) Let p = 3. Does the agent prefer to participate to the lottery or not participate? (d) What is the amount of dollars you should give the agent so that he is indifferent between participating to the lottery and not participating but getting the money?An agent makes decisions using U(ct) = (ct−χct−1)1−γ 1−γ . Answer the following: (a) Suppose χ = 0. Derive an expression for the coefficient of relative risk aversion RR(ct)? (b) Suppose 0 < χ ≤ 1.
