Sharon is a utility maximizer who consumes only X and Y. Her income (I) stays the same over the months of September and October. You are given the following information about her choices:
| Px | PY | X | Y | |
| Sep. 2016 | 20 | 10 | 10 | 30 |
| Oct. 2016 | 10 | 10 | ? |
? |
Sharon’s preferences are Cobb-Douglas. How much Y does she consume in October?
10
20
30
Not enough information to tell.
Correct Answer:
C
Consumption of Y, will remain same, because of price of Y has not yet changed. But, consumption of X will increase as price of X has decreases.

Sally consumes two goods, X and Y. Her preferences over consumption bundles are repre- sented by the utility function r, y)- .5,2 where denotes the quantity of good X and y denotes the quantity of good Y. The current market price for X is px 10 while the market price for Y is Pr = $5. Sally's current income is $500. (a) Write the expression for Sally's budget constraint. (1 point) (b) Find the optimal consumption bundle that Sally will...
A person has a Cobb Douglas utility function for two goods X and Y. If the price of a X increases and the budget stays the same, the utility maximizing person __________. Cannot be determined from the information will consume less of Y will only consume Y will consume less of both goods will have lower utility
A person has a Cobb Douglas utility function for two goods X and Y. If the price of a X decreases and the budget stays the same, then a utility maximizing person O will only consume X* O will consume more of Y Cannot be determined from the information will consume more of both goods will have higher utility

Clara consumes two goods x and y. Suppose her utility function is given as U(x,y)=min{3x,4y} The prices of the two goods are Px for good x and Py for good y. If her monthly income is $M, Derive her uncompensated demand function for good x Derive her uncompensated demand function for good y Derive the cross-price effects and show that the two goods are complementary goods.

Suppose James derives utility from two goods {x,y},
characterised by the following utility function: $u(x, y) =
2sqrt{x} + y$: his wealth is w = 10 let py = 1:
(a) What is his optimal basket if px = 0.50? What is her
utility?
(b) What is his optimal basket and utility if px = 0.20?
(c) Find the substitution effect and the income
effect associated with the price change.
(d) What is the change in consumer
surplus?

X-EC2010-1 1. An individual consumer with Cobb-Douglas preferences over two products, x and y, maximises utility, U(X.y) = x10y10, subject to the constraint that all income, M, is spent on x and/or y. Products x and y are priced at Px and Py, respectively. (a) Set up the appropriate lagrangian for this maximisation problem, find the appropriate first-order conditions for this lagrangian and solve for x and y in terms of px, Py and M. (40 marks) (6) For product...
Sally the Sleek’s preferences can be described by the utility function U(x, y) = x^2y^3/1000. Prices are px = 4 and py = 3; she has an income of $80 to spend. (a) If Sally initially consumed 5 units of x and 20 units of y, how much additional utility does she get from spending one (small fraction of a) dollar more on good x? How much additional utility does she get from spending one (small fraction of a) dollar...
Problem 1 (10 marks) Answer the following questions regarding a Cobb-Douglas utility function U(X,Y)= X0.3 0.7 (a) Does this utility function exhibit diminishing marginal utility in X? Show why or why not. (b) Does this utility function exhibit diminishing marginal rate of substitution? Mathematically show and verbally explain why it has (or doesn't have) such property. Problem 2 (10 marks) Consider the following utility function U(X,Y)= X14734 Suppose that prices and income are given as following Px= 1 Py =...
