Suppose a person has the utility function U=x^.75 and makes $52,000. If he gets the flu, he will have to miss work for a week, costing him $1,000. His probability of getting the flu is 15%. Compare the following scenarios and rank his preferences over them:

His current situation
Participate in the company’s sick day program where $500 of his salary is withheld (regardless of whether he gets sick) but if he gets sick for a week he doesn’t loose any additional money.
Buy a flu shot for $75 which lowers his chance of getting the flu to 10%
Buy a premium flu shot for $100 which lowers his chance of getting the flu to 5%

Which makes him best off?

Group of answer choices

Situation 1

Situation 4

Situation 3

Situation 2

Expert Solution

1)

Current situation=Situation 1

Expected utility=0.15*U(52000-1000)+(1-0..15)*U(52000)

Expected utility=0.15*(52000-1000)^0.75+(1-0.15)*(52000)^0.75=3436.05 utils

2)

Situation 2- Sick day program

Expected Utility=0.15*U(52000-500)+(1-0..15)*U(52000-500)

Expected utility=0.15*(52000-500)^0.75+(1-0..15)*(52000-500)^0.75=3418.66 utils

3)

Situation 3- buy a flu shot for $75

Expected Utility=0.10*U(52000-75-1000)+(1-0.1)*U(52000-75)

Expected Utility=0.10*(52000-75-1000)^0.75+(1-0.1)*(52000-75)^0.75=3434.81 utils

4)

Situation 4- buy a flu shot for $100

Expected Utility=0.05*U(52000-100-1000)+(1-0.0.05)*U(52000-100)

Expected Utility=0.05*(52000-100-1000)^0.75+(1-0.05)*(52000-100)^0.75=3436.06 utils

Expected utility is highest in case of situation 4. It will make him best off

Correct option is

Situation 4

A person has an expected utility function of the form U(W) = W . He owns a house worth $ 500,000. There is a 50% chance that the house will be burned down. Then, he will become literally penniless . Luckily, however, there are insurance companies which make up for losses from house fire. Currently, they charge $q for $1 compensation (in cases of fire). In other words, the home owner should pay $qK for K units of fire insurance...

Jack has a utility function u(x,y) = xy, and an endowment of (2,4). He has no other income. (a) Calculate the demands when the prices are px = 2, py = 4. (b) What are the net demands for the prices from (a)? (c) Let the prices be variables. Calculate the demands as functions of the prices. (d) Now let the prices and the endowments be variables. Calculate the demands as functions of the endowments and the prices.

Suppose a consumer's utility function is given by U ( X , Y ) = X 1 2 Y 1 2. The price of X is PX=8 and the price of Y is PY=5. The consumer has M=80 to spend. You may find that it helps to draw a graph to organize the information in this question. You may draw in the blank area on the front page of the assignment, but this graph will not be graded. a) (2...

Suppose a consumer has a utility function given by u(x, y) = x + y, so that the two goods are perfect substitutes. Use the Lagrangian method to fully characterize the solution to max(x,y) u(x, y) s.t. x + py ≤ m, x ≥ 0, y ≥ 0, where m > 0 and p < 1. Evaluate and interpret each of the multipliers in this case. What happens to your solution when p > 1? What about when p =...

Suppose a consumer has a utility function u(x, y) = 2x + 3y. The consumer has an income $40 and the price of x is $1 and the price of y is $2. Which bundle will the consumer choose to consume? Determine the demand functions for x and for y. Repeat the exercise if, instead, the consumer’s utility function is u(x, y) = min{x, 2y}.

Suppose that the utility function of a consumer is U(x,y) = x ¼y ¾, where x and y are the quantities of the good X and good Y consumed, respectively. The consumer's income is 400. (a) What is the demanded bundle when the price of good X is 10 and the price of good Y is 10? (b) Redo part (a) when the price of good X is doubled? (c) Redo part (a) when the price of good Y is...

Now, suppose Harry’s utility function is u (w) = ew - 1. He has a house of value $1,000,000. If earthquake comes, it will destroy his house and its value becomes zero. An insurance company provides insurance for those natural disasters. However, they cannot provide full insurance to the house. They provide insurance up to $500,000. The probability of the earthquake is 0.01%. The insurance fee is $0.02 per $1 insured asset. (i.e. if Harry insures $500,000, it will give...

Suppose a consumer has preferences represented by the utility function U(X,Y) = X2Y Suppose PY = 1, and the consumer has $300 to spend. Draw the Price-Consumption Curve for this consumer for income values PX = 1, PX = 2, and PX = 5. Your graph should accurately draw the budget constraints for each income level and specifically label the bundles that the consumer chooses for each income level. Also, for each bundle that the consumer chooses, draw the indifference...
