Instructor-created question A consumer's preferences are given by the following Cobb-Douglas utility function: Assume Px > 0, P, > 0, and I > 0 a. In the limit, what is the marginal utility of xas x goes to zero and what is the marginal utility of y as y goes to zero? lim MUY ra3 lim MU, -
1. When a consumer has a Cobb-Douglas utility function given by u(x, y) = xa yb , their demand for good x is given by x∗ = m/Px (a/a+b) where m is income and Px is the price of good x. Using this demand function, find the formula for this consumer’s price elasticity of demand. Interpret it in words.
4. Suppose you have the following Cobb-Douglas Utility Function: And $200 to spend. a. Use the method of Lagrangian Multipliers, to maximize this consumer's utility and derive demand equations for both goods. Sketch their respective demand curves. Show all work. (5 pts) b. If Px = Py = $1, how much utility will the consumer enjoy? Show work/explain. (2.5 pts) c. Does this allocation satisfy the rule of equal marginal utility per dollar spent? Explain/show work. (2.5 pts)
For all the utility functions (CES, Cobb-Douglas, quasi-linear, linear, Stone-Geary and Leontief) in the attached document, formally derive the Marshallian demand functions and the related expenditure functions.
If you have a Cobb-Douglas utility function U= Xα Yβ, what is your compensated demand function for good X?
Assume John has Cobb-Douglas utility function for bread (B) and whiskey (W): U- 2*B0.5w0.5 Marginal utilities are as followed: MUs B0sW05 and MUw Bo5w°s 0.5 1. Write down the expression for MRSBw 2. What is MRSBw at the bundle A(9,9)? 3. Does this utility function have diminishing MRS?
Q3: a. Consider a Cobb-Douglas Utility Function Find marginal utility of Y. Does marginal utility of depend on the level of consumption of X? how do you know? Explain b. Find slope of the indifference curve. c. Find MRS and draw the indifference curve for above function.

What is total factor productivity? 2. With your answer in (1), assume L=95 and estimate the production function with respect to K 3. Estimate the marginal product of capital and demonstrate diminishing marginal product of capital 4. Estimate real capital income 5. Estimate the share of capital income...
4) A consumer's utility function is Cobb-Douglas ulx, y2y2 Yesterday prices were P:-1, p,-1; today prices are p,-1, p,-2. Încome in both dates is I 120. (a) What was the consumer's optimal choice yesterday? (b) What is the consumer's optimal choice today? fa subsidy would I have to provide so that the consumer obtain the same utility today as yesterday? today? (This is compensated demand.) obtain the same bundle of goods today as yesterday? Is this more or less d)...
Assume John has Cobb-Douglas utility function for bread (B) and whiskey (W): U= 2 BSWS Marginal utilities are as followed: MUB=B-05W. and MUw = 30.5W-0.5 a. Write down the expression for MRSow (i.e., you need to simplify the ratio and come up with a neat result) b. What is MRSBw at bundle A(4,4)? At bundle B(1,16)? C. Regarding MRSBw, we consider a movement along an indifference curve from the left to the righ (getting more of bread, the good on...
