Question
I have answer but do not know parts e as well as others
please teach explain step by step,
A consumer has preferences over two goods represented by the utility function u(x₁, x2):
*1 +2√x2.
(a) Sketch this consumer's indifference curves.
(b) Find the Marshallian demand function x(p, w).
(c) Sketch the wealth expansion path; that is, fixing prices p, sketch the demands xp, w) in
(1,2)-space as wealth w varies.
(d) Find the indirect utility function v(p, w).
(e) Use your answer from part (d) to find the Marshallian demand (again) without solving
the utility maximization problem.
(
(f) Suppose that, initially, prices are p = (P₁, P2) and the consumer has wealth w satisfying
w>. If the price of good one doubles while, at the same time, the price of good two
is cut in half, is the consumer made better or worse off (or is it impossible to determine)?
(g) Find the expenditure function e(p, u) without solving the expenditure minimization
problem.
(h) Use your answer from part (g) to find the Hicksian demand function h(p, u).
'ence we have :
MU₁
MU
=
> Px1X1 + Px2
P₁1
Pa
√x2=
=
required marshallian demand for good 2
ubstituting this in the given budget equation we get :
> Px1X1 + PxX2 = M
P 2
P₁
P₁
Pa
= M => X1 =
M
Pat
=> x2 =
