An individual has preferences over housing, x (measured in square metres), and other goods, y, represented by utility function u(x,y) = x4y. Her disposable income is $75000, and the price of housing is $1000/m2, while that of other goods is py = $1.
a) [5 marks] Find this consumer’s optimal bundle and utility level, given initial prices and income.

An individual has preferences over housing, x (measured in square metres), and other goods, y, represented by utility function u(x,y) = x4y. Her disposable income is $75000, and the price of housing is $1000/m2, while that of other goods is py = $1. b) [5 marks] The government decides to subsidize housing at a rate of 20%. Find the resulting optimal bundle and utility level.

Problem 1. The preferences of an average smoker between cigarettes (X) and other goods (Y) can be described by U(X,Y)=XY. The smoker's income is M=$800, and Py = $50. a) What is the smoker's optimal bundle when P =$8? X = Y = U= b) In order to reduce smoking, a tax on cigarettes is introduced. As a result, Px increases to $10. What is the new optimal consumption bundle? X = Y = U= c) Estimate the smoker's elasticity...

Long Question #2 Consider preferences over food and housing represented by the utility function U F2/3H1/3 A. Let Income 1200, PE 2 and PH6. Find the quantity demanded of housing and food. Graph the budget constraint and the optimal bundle that you found. Make sure to include an indifference curve. Let the price of food increase to 4. Add the new budget constraint, find the new optimal bundle and add it to your graph. B.

3. Suppose an individual has perfect-complements preferences that can be represented by the utility function U(x,y)= min[3x,2y]. Furthermore, suppose that she faces a standard linear budget constraint, with income denoted by m and prices denoted by px and p,, respectively. a) Derive the demand functions for x and y. b) How does demand for the two goods depend on the prices, p, and p, ? Explain.

Ahn’s utility function for goods X (pizzas) and Y (cola) is represented as U(X, Y) = 2ln(X)+ln(Y). The prices of X and Y are $1 and $1, respectively. Ahn’s income is $12. 1) Calculate Ahn’s optimal consumption bundle (X*, Y*). (X*, Y*)= . 2) Suppose there is an increase in the price of X. Illustrate the net effect, income effect, and substitution effect on Ahn’s optimal consumption choice.

Utility maximization with more than two goods Suppose that there four goods Q, R, X and Y , available in arbitrary non-negative quantities (so the the consumption set is R 4 +). A typical consumption bundle is therefore a vector (q, r, x, y), where q ≥ 0 is the quantity of good Q, r ≥ 0 is the quantity of good R, x ≥ 0 is the quantity of good X, and y ≥ 0 is the quantity of...
