Total effect = SE + IE = -3.9 + 1 = -2.9
So, quantity of good 1 decreases by 2.9 units with decrease in its
price. So, good 1 is a giffen good because quantity of giffen good
decrease with decrease in price.
A consumer has the demand function x* = x1(P1, m). When the price of good one...
A consumer has income M, and faces prices (for goods 1 and 2) p1 and p2. For each of the following utility functions, graphically show the following: (i) the Slutsky substitution and income e⁄ects when p1 decreases. (ii) the Hicks substitution and income e⁄ects when p1 decreases. (iii) the Marshallian and Hicksian demand curves for good 1: (a) perfect complements: U(x1 , x2) = min {4x1, 5x2} (b) quasi-linear: U(x1 , x2) = x^2/3 1 + x2
7. Jay's Utility function is given by U(x,z) = 3x10.2 x20.8 and P1=$2 and P2=$4 and his budget is $200. Write out the Lagrange but DO NOT solve it Find the utility maximizing values of x1and x2 8. What does the substitution effect cause a consumer to do if the price of a good increases? 9. What does the income effect cause a consumer to do if the price of a good increases? What else is needed here? 10. What...
3. Suppose a consumer’s demand function for milk is x1 = 1/4 * m/p1, or (m/4p1), where p1 is the price of milk and x1 is the quantity of milk. Let the consumer’s income be $120/week and the price of milk be $3/quart. Suppose the price of milk falls to? $2/quart. (a) (1) How much is the Slutsky compensation? (Specify whether it is given or taken away.) (b) (2) How much is the Slutsky substitution effect? (c) (2) How much...
5. Melissa’s utility function for the bundle (x,y) is U(x,y)=xy. Price of good x is p1=1, price of good 2 is p2=2 and income m=10. If the price of good 1 goes up to p1=2, but the rest remain the same. Derive: Total effect? Substitution effect? Income effect?
Assume a consumer is consuming x1 and x2. Price of good 1 is p1 and price of good 2 is p2. Suppose the utility function of this consumer is 1. Find the Hicksian demands for both goods 1 and 2. Show all of your steps 2. Find the expenditure function. Show all of your steps 14*,'* = (*x*\x)n
The utility function is u = x1½ + x2, and the budget constraint is m = p1x1 + p2x2. Derive the optimal demand curve for good 1, x1(p1, p2), and good 2, x2(m, p1, p2). Looking at the cross price effects (∂x1/∂p2 and ∂x2/∂p1) are goods x1 and x2 substitutes or complements? Looking at income effects (∂x1/∂m and ∂x2/∂m) are goods x1 and x2 inferior, normal or neither? Assume m=100, p1=0.5 and p2=1. Using the demand function you derived in...
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.
U(x, y) = x1ax2(1-a) Solve for the marshallian demands for x1 and x2, as functions of p1, p2, and m. (Hint: your solutions will be equations, not numbers). For x1 find the own-price elasticity and income elasticity. Suppose a = 0.2, m = 100, p1 = 2, and p2=8, find the quantities of x1 and x2. What happens to these quantities when p1 doubles to $4? What does this say about the price consumption curve (PCC)? 2. Suppose the price...
Suppose a consumer has a utility function U (x1,x2) = Inxi + x2. The consumer takes prices (p1 and p2) and income (I) as given 1) Find the demand functions for x1 and x2 assuming -> 1. What is special about Р2 these demand functions? Are both goods normal? Are these tastes homothetic? <1. You probably P2 2) Now find the demand functions for x1 and x2 assuming assumed the opposite above, so now will you find something different. Explain....
A consumer has a demand function for good 2, ?2, that depends on the price of good 1, ?1, the price of good 2, ?2, and income, ?, given by ?2 = 2 + 240 + 2?1. Initially, assume ? = ??2 40, ?2 = 1, and ?1 = 2. Then the price of good 2 increases to ?2′ = 3. a) What is the total change in demand for good 2? [2 marks] b) Calculate the amount of good...
