3) Consider preferences given by the utility function ?(?1, ?2) = ?1^2 + ?2. Derive the MRS and the individual demands for each of the two goods. How an increase in income would affect the demand of each good?
U = x12 + x2
Budget line: M = p1.x1 + p2.x2
MU1 =
U/
x1
= 2x1
MU2 =
U/
x2
= 1
MRS = MU1/MU2 = 2x1/1 = 2x1
Utility is maximized when MRS = p1/p2
2x1 = p1/p2
2p1.x1 = p2
p1.x1 = p2/2
x1 = (p2/2p1)
Substituting in budget line,
M = p1.x1 + p2.x2
M = (p2/2) + p2.x2
2M = p2 + 2p2.x2
2p2.x2 = 2M - p2
x2 = (2M - p2)/2p2
Demand function of x1 is independent of M, so increase in M does not affect demand for x1.
From demand function of x2, s M increases, (2M - p2) increases and so, demand for x2 increases.
