Problem 18. Suppose we want to maximize the utility function u = x²y subject to the following two constraints: x + y ≤ 100 and 2x + 8y ≤ 240. Also, x and y must be greater than or equal to 0.

Write the Lagrangian function L.
Write the Kuhn-Tucker conditions for this problem.

Suppose a consumer seeks to maximize the utility function U (x1; x2) = (-1/x1)-(1/x2) ; subject to the budget constraint p1x1 + p2x2 = Y; where x1 and x2 represent the quantities of goods consumed, p1 and p2 are the prices of the two goods and Y represents the consumer's income. (a)What is the Lagrangian function for this problem? Find the consumer's demand functions, x1 and x2 . (b) Show the bordered Hessian matrix, H for this problem. What does...

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...

Suppose that an individual has a utility function of the form U = Y½ where U is utility and Y is income. a) Calculate the utility level for Y values of $10,000, $40,000, $90,000, $160,000, and $250,000 and then plot the individual’s total utility function. b) This individual is currently earning $90,000 but has a 50-50 chance of earning either $40,000 or $160,000 in a new job. i) Calculate the expected income and utility from the new...

Questions 11-13 relate to the following consumer utility maximization problem: maximize U(x,y)=x^0.75y^.25 subject to the budget constraint 10x+5y=40. A) What is the optimal amount of x in the consumer's bundle? (Note that the 10 in the budget constraint is interpreted as the price of good x, 5 is the price of good y, and 40 is the consumer's income.) B) What is the optimal amount of y in the consumer's bundle? C) What is the consumer's maximized utility?

Example: Consider a person with this utility function: U = C – N^2.5 Subject to: C = w(1-t)N , With the wage w and the tax rate t exogenous. a. Find the optimal labor input (N) solely as a function of exogenous parameters. b. What’s the elasticity of labor supply for this person? Answer with a precise number. c. If the tax rate is 50% and the wage is 10, exactly how many units of labor will this person supply?...
