(5) A consumer has the following utility function: U(x, y) = (x+2)(y+1), where x and
y are quantities of two consumption goods whose prices are P, and Py, respectively. The
consumer also has a budget of B.
(a) Write down the consumer's Lagrangian associated with this primal problem. From
the first-order conditions, find expressions for the demand functions x and y.
(b) Find the expression for indirect utility function U = U(P, P, B) (namely the
maximum value function).
(c) Write down the associate dual problem with a target level of utility U. Derive an
expression for the expenditure function E = E(P, P, U") of the dual problem.
(d) Use Shephard's Lemma to find the Hicksian demands of associated dual problem,
i.e., OE/OP, rh, OE/OP, y", and OE/OU= u", where " is the Lagrangian multiplier
in this problem.
