Suppose the expenditure function is e(p, u) = p1 * p2 + 2p1^1/2
* p2^ 1/2 * u. Then ∂e/∂p1 (p, u) = p2 + (p2/p1)^1/2*u and
∂e/∂p2(p, u) = p1 + (p1/p2)^1/2*u
(a) Find the Hicksian demand function h(p, u).
(b) Find the indirect utility function v(p,w) (this should be a
function of w, p1, and p2).
(c) Find the demand function x(p, w). Are goods 1 and 2
substitutes or complements?
