Consider an individual making choices over two goods, x and y with initial prices px=5 and py= 2, with income I= 100:
a) If the individual's preferences can be represented by the utility function u = 4x+ 2y; find the income, substitution and total effects of a decrease in the price of x to px= 3.
b) If the individual's preferences can be represented by the utility function u = min(4x,2y); find the income, substitution and total effects of a decrease in the price of x to px= 3.
c) If the individual’s preferences can be represented by the utility function u= 4xy, and the income, substitution and total effects of a decrease in the price of x to px= 4.

4. An individual has preferences over two goods (x and y) that are represented by function U = min{x,y}. The individual has income $60, the price of x is $4 and the price of good y is $2. (a) What kind of goods are these to the individual? (i.e. what "special case” is this?) (b) What is this individual's budget constraint? (c) What is this individual's optimal bundle of x and y? [HINT: You can't take the derivative of this...
Suppose the preferences of an individual are represented by a quasilinear utility function: U (x, y) = ln(x) + y (a)Suppose px =1, py =5 and I = 20. The price of x increases to 2 (px = 2). Calculate the changes in the demand for x. What can you say about the substitution and income effects for small changes in the price of x? What happens to the demand for y? Is y a gross substitute? (b)Now suppose px...
(b) You consume two goods, good x and good y. These goods sell at prices px = 1 and py = 1, respectively. Your preferences are represented by the following utility function: U(x; y) = x + ln(y): You have an income of m = 100. How many units of x and y will you buy and what will is your utility? If px increases from $1 to $2; figure out the compensating variation (CV) associated with price change. (c)...
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.
Consider preferences over x and y given U(x,y) = min(x,2y) and suppose that income is 60. Let the initial prices be px=1 and py=2. 1. What is the initial optimal consumption? 2. Suppose px increases to px=2. Find the total change in the consumption of x and y. 3. Decompose the total effect into its substitution effect and its income effect. Please do each step of every question for a complete understanding of the reasoning behind the steps.
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.
2. Jane's utility function defined over two goods and y is U (x, y) = !/2y\/? Her income is M and the prices of the two goods are p, and Py. (e) Determine the substitution and income effects for good when ini- tially M = $12. Pa = $2, Py = $1, and then the price of good rises to $3. (f) Show the effects from the previous part graphically. (g) How many dollars is Jane willing to accept as...
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.
2. Consider a utility function that represents preferences: u(x,y)= min{80x,40y} Find the optimal values of x and y as a function of the prices px and py with an income level m. (5)
