Section I: Derivation of Hicksian Demand Curve
Joyce’s utility function is as follows:
U= 10X3Y2
Where, X, is the quantity of good X consumed, Y, is the quantity of good Y consumed and, U, is Joyce’s utility function.
The general budget constraint for the two goods is a follow:
B= PXX + PYY
Derive Joyce’s Marshallian demand equation for good X. Also compute her demand for good X when B= 500, and the price of good X is 1 and 2. Also draw the Marshallian demand curve for X at these prices.
What is Joyce’s optimal amount of good Y purchased if PY= 1 and Px=1 and if Px=2 and PY= 1?
Derive the Hicksian demand for good X at these prices. Hint, you need to choose the three correct equations you’ve derived above and solve simultaneously. Also, draw both demand curves on the same graph.
Using the information derived in parts A and B, what is the substitution effect and income effect obtained when changing the price of good x from a value of 1 to a value of 2.
