To determine the demands of both consumers for both goods and identify whether the resulting profile constitutes a Walrasian equilibrium, we need to solve the consumer optimization problems for each consumer given the price vector p.For Consumer 1:
The consumer aims to maximize their utility subject to their budget constraint. The budget constraint is given by:
Substituting the given values, we have:
Simplifying, we get:
The consumer's optimization problem is:
subject to:
The consumer will choose the bundle
such that
. Substituting this into the budget constraint, we get:
Solving for x, we get:
Substituting this back into
, we get:
Therefore, Consumer 1's demand for good x is
and for good y is
.For Consumer 2:
The consumer aims to maximize their utility subject to their budget constraint. The budget constraint is given by:
Substituting the given values, we have:
Simplifying, we get:
The consumer's optimization problem is:
subject to:
The consumer will choose the bundle
such that
. Substituting this into the budget constraint, we get:
Solving for y, we get:
Substituting this back into
, we get:
Therefore, Consumer 2's demand for good x is 0 and for good y is
.Now, let's check if the resulting profile constitutes a Walrasian equilibrium. A Walrasian equilibrium occurs when the demands of both consumers for both goods are such that the market clears, meaning that the total demand for each good equals the total supply.In this case, the total demand for good x is
and the total supply is 2. The total demand for good y is
and the total supply is 2. Since the total demand for both goods does not equal the total supply, the resulting profile does not constitute a Walrasian equilibrium.Therefore, the answer is:for
Is it a WE equilibrium?No
