Suppose there are two consumers, A and B. The utility functions of each consumer are given by: UA(X,Y) = X 2 Y UB(X,Y) = X*Y
Suppose there are two consumers, A and B.
The utility functions of each consumer are given by:
UA(X,Y) = X2Y
UB(X,Y) = X*Y
Therefore:
- For consumer A: MUX= 2XY; MUY= X2
- For consumer B: MUX= Y; MUY= X
The initial endowments are:
A: X = 90; Y = 12
B: X = 60; Y = 8
a)Suppose the price of Y, PY= 1.Calculate the price of X, PXthat will lead to a competitive equilibrium.
b) 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) What is the marginal rate of substitution for consumer A at the competitive equilibrium?
