3. A firm has a cost function of the form: C(2₁. 22. q) = w25 25 25 25 ² where Z₁...2 are factor inputs, ...., w are factor wages, q is the firm's output, a is a positive constant, a > 0. (a) What are the conditional factor demands? Is the production function homothetic? (b) Set up the firm's maximization problem given the wages w and the price of the final output p. (c) Solve the firm's profit maximization problem. Indicate for what values of a this problem leads to a finite and unique profit-maximizing output (use second order conditions). Relate this problem to the returns to scale.

3. A firm has a cost function of the form:
%3D
where z1.....z4 are factor inputs, w..., w4 are factor wages, q is the firm's output, a is a positive constant, a > 0.
(a) What are the conditional factor demands? Is the production function homothetic?
(b) Set up the firm's maximization problem given the wages w and the price of the final output p.
(c) Solve the firm's profit maximization problem. Indicate for what values of a this problem leads to a finite and unique profit-maximizing
output (use second order conditions). Relate this problem to the returns to scale.
(d) Write down the firm profit function a(p, w) for the range of a found in (c).
