In: Economics
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 = 75; Y = 15 B: X = 75; Y = 5
a) (20 points) Suppose the price of Y, PY = 1. Calculate the price of X, PX that will lead to a competitive equilibrium. b) (8 points) 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) (4 points) What is the marginal rate of substitution for consumer A at the competitive equilibrium?
