2. An individual has a vNM utility function over money of u(x) -Vx, where x is final wealth. Assume the individual currently has $16. He is offered a lottery with three possible outcomes; he could gain an extra S9, lose $7, or not lose or gain anything. There is a 15% probability that he will win the extra $9, what minimum probability, p, of losing S7 would ensure that the individual chooses to not play the lottery? (a) p >...
6. A decision maker has a vNM utility function over money of u(x) = x2. This decision maker is (a) risk-averse. (b) risk-neutral. (c) risk-loving. (d) none of the above. 7. Consider two lotteries: • Lottery 1: The gamble (0.1, 0.6, 0.3) over the final wealth levels ($1, $2, $3). (The expected value of this lottery equals $2.2) • Lottery 2: Get $2.2 for sure. a) Any risk-averse individual will choose the first lottery. b) Any risk-averse individual will choose...
8. An individual with utility function over money u(w) = 8Vw has $C in cash and a lottery ticket that pays $W if it wins and nothing if it loses. The probability of winning is .. Suppose an insurance is available at price $p per unit, where each unit of insurance pays $1 if the ticket does not win and nothing if it wins. (a) Is the individual risk averse, risk neutral, or risk loving? (b) What is the fair...
6. Consider an individual whose utility function over money is u(w)= 1+2w2. (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...
(1) Ann has vNM utility u1 (x) = x, Bob has utility u2 (x) = √ x and Carl has utility u3 (x) = x 3 . Who is risk neutral, risk averse and risk loving? (2) Consider the lottery P again. Find the dollar amount x such that each person is indifferent between the lottery P and $x (x is the certainty equivalent of P) (3) Calculate the Arrow-Pratt coefficients for everyone. How do they compare? Does this agree...
Suppose you are facing a lottery that has a payoff of 10b pounds with probability 0.01 and that of 0 with probability 0.99. You are an expected utility maximiser with a utility function,u(x) = −exp(−ax) where x is the payoff in money terms and a > 0 is a parameter. What is the risk premium for this lottery - describe the risk premium as a function of ‘a’ and ‘b’.
3. Suppose an individual has a utility function U=U(M, X)=10 MX^2, where U is her utility, M is her(daily) money income and x is her(daily) leisure hours.

4. An individual has preferences represented by the utility function U(x,y)=(x12+yızg Which of the following statements concerning her MRS is false? a. If the individual has 4 units of x and 36 units of y, she would be willing to trade a b. If the individual has 8 units of x and 2 units of y, the MRS of x for y at that point would c. If the individual has 16 units of x and 4 units of y,...
A consumer who has $1000 is represented by the expected utility function u(x) = √x. A lottery ticket is sold at $80 whose prize is $10000 with probability 1/10 and zero with probability 9/10 Find the certainty equivalent of the lottery ticket. Find the risk premium of the lottery ticket. Should this consumer buy the ticket? Why?
