19. An individual has initial wealth Wo = 3 and has the opportunity to invest some quantity of money x in an extremely risky corporate bond. With probability p= 1/4, the bond will be worth 10x at maturity. With probability 1 – p, it will be worth zero. The individual's utility function over final wealth is u(W) = W0.5. What is the level of investment x that maximizes expected utility? (а) 0 (b) 1 (c) 4/3 (d) V3 (e) 2

8 An investor with initial wealth $20000 and utility function U(x) = ln(x) is considering an investment that has a 80% chance of gaining r% and a 20% chance of losing s%. (1) Find in terms of r and s the certainty equivalent of this investment. (2) If s = 10, find the range of values of r for which the investor will avoid this investment.,
a) Explain what is meant by risk aversion, and illustrate with the help of a figure out what we mean by the term "risk premium". Suppose Donald runs hotels and casinos, which makes one very insecure income. With probability 1 the income becomes 100 and with probability 1 the 64th Donald's expected income is thus equal to 82. Further assume that the utility to Donald is a a function of income, and that it is given by U (x) = 2x 12 x is the income level. b) Calculate Donald's expected utility.
10. Karl's utility function is U(w) = 20 is w. = 300. He considers a gamble in which he could win 200 with probability p or lose 200 with probability 1 described by expected utility theory. He is indifferent between keeping his initial wealth for sure or taking the gamble if the value of p is where w is wealth. His initial wealth %3D w+200 - p. Karl's preferences in the face of risk are (a). 4 (b) .5 (c) .6 (d) .7 (e) .8
10. BB has an endowment (E) which she can invest. With probability p, the investment works out well and BB ends up with E(1+r) but, with probability 1-p, BB loses all of her money. a) If BB is risk neutral, what is the lowest value of p for which she should invest? b) What is the expected value of perfect information? c) Now assume BB is risk averse with utility of money function U(m) = m1/2. What fraction, x, of her endowment should BB invest?
# 4 Consider an individual with a utility function of the form u(w) = √w. The individual has an initial wealth of $4. He has two investments options available to him. He can eitffer keep his wealth in an interest-free account or he can take part in a particularly generous lottery that provides $12 with probability of 1/2 and $0 with probability 1/2. Assume that this person does not have to incur a cost if he decides to take part in the lottery. (a) Will this individual participate in the lottery? (b) Calculate this individual's certainty equivalent associated with the lottery. What is his risk premium?
3) A risk-loving individual has $1000 to invest. The individual maximizes his/her expected utility and has a monotonic utility function. Show that he/she will never choose a diversified portfolio - that is, show that he/she will either keep the entire $1000 in a safe, or invest the entire $1000 in a risky assesst, for which each $1 invested yields $] with probability p, and SB with probability (1-p), where $B<$1<$J.
Economics Shawn's consumption is subject to risk. With probability 0.75 he will enjoy 10000 in consumption, but with probability 0.25 he will have only 3600. His utility function for consumption is given by v(c) = Vc. -What is the expected value of Shawn's consumption? -What is his expected utility? -What is his certainty equivalent of having 10000 with probability 0.75 and 3600 with probability 0.25?
5. An individual has a utility function given by (W) - √W, and initial wealth of $100. If he plays a costless lottery in which he can win or lose $10 at the flip of a coin, compute his expected utility. What is the expected gain? Will such a person be categorized as risk neutral?
Please explain in detail about expected utility to get a positive upvote. An individual has a utility function U = W¼, where W is her total wealth.

Economics Fenner Smith from Workouts 13.2 is an investor who has preferences for risk o and returnu given by the utility function u = min (µ, 4 –0). He plans to invest $40,000. The market rate of return is 8 percent and the risk-free rate of return is 2 percent. The risk on the market portfolio is 2 percent. a. How much of his $40,000 will a utility maximizing investor hold in the market portfolio? Show this as Bundle A in your diagram. b. The market return rises to 16 percent.How much of his $40,000 will he hold in the market portfolio. Show this as Bundle C in your diagram. c. Calculate the Hicksian ČV for this change. Show this in your diagram as Bundle B.
7. Consider an individual whose utility function over money is u(w) = 1+2w. (a) Is the individual risk-averse, risk-neutral, or risk-loving? Does it depend on w? (b) Suppose the individual has initial wealth ¥W and faces the possible loss of Y. The probability that the loss will occur is . Suppose insurance is available at price p, where p is not necessarily the fair price. Find the optimal amount of insurance the individual should buy. You may assume that the solution is interior. (c) Is there a price at which the individual will not want to buy any insurance? If so, find it. If no, explain.
Millicent’s utility function is U(w) = W0.5 , where W is her wealth. She owns a “pure water” producing firm that will be worth GH100 or 0 Ghana cedis next year with equal probability. a. Suppose her firm is the only asset she has. What is the lowest price at which she will agree to sell her pure water? (Hint: price=amount that will give her the same expected utility) b. Assume that she has GH200 safely stored under her mattress, find the new lowest price at which she will agree to sell her “pure water” producing firm c. From your answers in parts (a) and (b), what is the relationship between her wealth and her degree of risk aversion?
