Sub part (a):
Diminishing marginal utility .
Sub part (a):
Explanation of Solution
The utility function is
Figure 1 illustrates the diminishing marginal utility.
In Figure 1, the horizontal axis measures the quantity of wealth and the vertical axis measures the utility. When the quantity of wealth increases then the additional utility decreases.
Concept introduction:
Marginal utility: Marginal utility refers to the additional units of satisfaction derived from one more additional unit of goods and services.
Diminishing marginal utility: Diminishing marginal utility refers to a decrease in the additional satisfaction as a result of increasing the consumption.
Sub Part (b):
Expected value.
Sub Part (b):
Explanation of Solution
Since the value is sure, the probability is 1. Expected value of A can be calculated as follows:
Expected value of A is $4,000,000.
Expected value of B can be calculated as follows.
Expected value of B is $4,200,000. Thus, B offers higher value.
Concept introduction:
Risk is the future uncertainty about deviation from expected earnings or expected outcome. Risk measures the uncertainty situation that an investor is willing to take to realize a gain from an investment.
Risk aversion: Risk aversion can be defined as it is a dislike of an uncertainty.
Marginal utility: Marginal utility refers to the additional units of satisfaction derived from one more additional unit of goods and services.
Diminishing marginal utility: Diminishing marginal utility refers to a decrease in the additional satisfaction as a result of increasing the consumption.
Sub part (c):
Expected utility.
Sub part (c):
Explanation of Solution
Expected utility of A can be calculated as follows:
Expected utility of A is $2,000.
Expected utility of B can be calculated as follows.
Expected utility of B is $1,800.
Concept introduction:
Risk is the future uncertainty about deviation from expected earnings or expected outcome. Risk measures the uncertainty situation that an investor is willing to take to realize a gain from an investment.
Risk aversion: Risk aversion can be defined as it is a dislike of an uncertainty.
Marginal utility: Marginal utility refers to the additional units of satisfaction derived from one more additional unit of goods and services.
Diminishing marginal utility: Diminishing marginal utility refers to a decrease in the additional satisfaction as a result of increasing the consumption.

Sub part (d):
Explanation of Solution
Since the expected utility from B is greater than A, the person should select A.

- Alex has a utility function U = W2, where W is his wealth in millions of dollars and U is the utility he obtains from that wealth. In the final stage of a game show, the host offers Alex a choice between (A) $9 million for sure, or (B) a gamble that pays $1 million with probability 0.4 and $16 million with probability 0.6. Use the blue curve (circle points) to graph Alex's utility function at wealth levels of $0, $1 million, $4 million, $9 million, and $16 million.

His utility is given by u(W) = 1 - (5,000/W), where W is his wealth. Max's total wealth is $15,000. With probability p = 0.7 the palace will succeed and Max's wealth will grow from $15,000 to $x. With probability 1 - p the palace will be a failure and he’ll lose $10,000, so that his wealth will be just $5,000. What is the smallest value of x that would be sufficient to make Max want to invest in the pinball palace rather than have a wealth of $15,000 with certainty? (Please round your final answer to the whole dollar, if necessary)arrow_forwardJamal has a utility function U= W1/2 where Wis his wealth in millions of 'dollars and Uis the utility he obtains from that wealth. In the final stage of a game show, the host offers Jamal a choice between (A) $4 million for sure, or (B) a gamble that pays $1million with a probability of 0.6 and $9 million with a probability of 0.4. a. Graph Jamal's utility function. Is he risk-averse? Explain. b. Does A or B offer, Jamal, a higher expected price? Explain your reasoning with appropriate calculations. (Hint: The expected value of a random variable is the weighted average of the possible outcomes, where the probabilities are the weights.) c. Does A or B offer Jamal a higher expected utility? Again, show your calculations. d. Should Jamal pick A or B? Why?arrow_forward

Wilfred is offered a choice between getting a sure payment of $Z or a lottery in which he receives $2500 with probability p = 0.4 and $3700 with probability 1 - p. Wilfred will choose the sure payment if Z > CE and the lottery if Z < CE, where the value of CE is equal to ___ (please round your final answer to two decimal places if necessary)arrow_forwardAmy likes to go fast in her new Mustang GT. Their utility function over wealth is v(w) where w is wealth. If Amy goes fast she gets an increase in utility equal to F. But when Amy drives fast, she is more likely to crash: when she drives fast the probability of a crash is 10%, but when she obeys the speed limit, the probability of a crash is only 5%. Amy's car is worth $2000 unless she crashes, in which case it is worth $0. If Amy doesn't have insurance, driving fast isn't worth the risk, so she will alway obey the speed limit. If Amy is offered an insurance contract with full insurance for a premium P with the deductible D, which of the inequalites below is her incentive compatibility constraint that makes sure that she will still obey the speed limit even when she is fully insured? 0.05U(2000 – P – D) + 0.95U(2000 – P) > 0.05U(0 – P – D + 2000) + 0.95U(2000 – P) 0.05U(2000 – P – D) + 0.95U(2000 – P) > 0.1(U(2000 – P – D) + F) + 0.90(U(2000 – P) + F) 0.05U(2000 – P – D) + 0.95U(2000)…arrow_forward

- Kindly solve 3rd question onlyarrow_forward# 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?arrow_forwardText of the problem from 'An introduction to decision theory' by Martin Peterson: You prefer a fifty-fifty chance of winning either $100 or $10 to a lottery in which you win $200 with a probability of 1/4, $50 with a probability of 1/4, and $10 with a probability of 1/2. You also prefer a fifty-fifty chance of winning either $200 or $50 to receiving $100 for sure. Are your preferences consistent with von Neumann and Morgenstern’s axioms? The book proposes as solution 'No. Your preferences violate the independence axiom.' without proposing the steps to reach that solution and I don't know why it is correct.arrow_forward
