Utility function is ? = x + 2y. (a) Does ‘income effect’ exist? (b) Does ‘substitution effect’ exist? Now utility function changes to ? = min[?, ?]. (c) Does ‘income effect’ exist? (d) Does ‘substitution effect’ exist?
Homework Answers
U= x+2y
a.This shows that x and y are perfect substitutes where there is no income effect.
b.Only substitution effect exists
U= min[x,y]
c.This shows that x and y are perfect complement where there is only income effect
d.No substitution effect exists.

Substitution and income effect
consumer has a following utility function: U(X,Y)=X^2 • Y, price of X increased. We can cunclude that:A)it's possible that substitution effect= real income effect on xB) HICKS substitution effect < SLUTZKY substitution effect in absolute valuesC)the real income effect= subsituion effect on YD) none of the above

Given a utility function U(x,y) = xy. The price of x is Px, while the price of y is Py. The income is I. Suppose at period 0, Px = Py = $1 and income = $8. At period 1, price of x (Px) is changed to $4. Compute the price effect, substitution effect, and
Given a utility function U(x,y) = xy. The price of x is Px, while the price of y is Py. The income is I. Suppose at period 0, Px = Py = $1 and income = $8. At period 1, price of x (Px) is changed to $4. Compute the price effect, substitution effect, and income effect for good x from the price change.

Suppose a consumer’s utility function is given by U(X,Y) = X*Y. Also, the consumer has $180 to spend, and the price of X, PX = 4.50, and the price of Y, PY = 2 a. How much X and Y should the consumer purchase in order to maximize her utility? b. How much total utility does the consumer receive? c. Now suppose PX decreases to 2. What is the new bundle of X and Y that the consumer will demand?...
