Question
Suppose there are two consumers, A and B.
The utility functions of each consumer are given by:
UAIX,Y) =X'Y
UBIX,Y) = x+Y3
Therefore:
• For consumer A: MUx = Y; MUY = X
For consumer B: MUx = Y³; MUY = 3XY²
The initial endowments are:
A: X 8; Y=6
B: X 14; Y 17
a)
b)
Suppose the price of Y, Py = 1. Calculate the price of X, Px that will lead to a competitive equilibrium.
How much of each good does each consumer demand in equilibrium?
Consumer A's Demand for X:
Consumer A's Demand for Y
Consumer B's demand for X
Consumer B's demand for Y
c) 1
What is the marginal rate of substitution for consumer A at the competitive equilibrium?
