1. NS 3.4 ("As we saw in Figure 3.5,..")
2. Let u : R 二 R be a continuously di§erentiable utility function satisfying the usual assumptions, and let f : R 二 R be a monotonic transformation of u: Consider the consumer problem of maximizing utility subject to the budget constraint. Show that the transformation f = f(u(x)) gives the same solution as u(x): Assume an interior solution.
3. An individual has the following preferences deÖned on consumption vectors x e R :
n n
u(x) =Ⅱxi(a)á where αi > 0 and Ω αi = 1 (1)
i=l i=l
His wealth is w e R++ and the price vector is p e R :
(a) Identify the constraint set X:
(b) Solve the problem.
(c) Discuss whether the necessary conditions are also su¢ cient.
(d) Find the indirect utility function v(p; w) = maxx ∈X u(x):
4. A consumer has the following preferences over x :
u(x) = max{axl ; ax2 } + min{xl ; x2 } (2)
where 0 < a < 1: Find the consumerís Marshallian demand curves if her wealth is w e R++ and prices are p = R :
5. NS 4.2 ("A young consumer has $600.....í)
6. NS 4.4 ("Mr. Odde Ball enjoys commodities x and y....")
