(A):
i) Restate the consumer problem.
ii) Form the Lagrangian function.
iii) Find the first-order-conditions (FOC).
iv) Divide Lx, by Lx,-
v) From iv), can you determine the type of goods 1 and 2 are?
(В):
Draw the indifference curves for U = X1 + x2, where U = 1 and 2.
What happens to the optimal demand for good 1, when:
P1 < P2
2. P1 > P2
1.
3. Pi = P2
