(b) Prove that the per-worker production function has the following properties: f'(k) > 0, lim f' (k) = +0, and k-0 lim f'(k) = 0. (c) Assume that the production factors receive their respective marginal products. Derive the expressions for the wage rate, W, and the rental rate on capital, r+ 8, when technology is Cobb-Douglas. What happens to (W,r) as k 0 and as k → o0? Derive the expression for the factor price frontier (FPF), i.e. the expression linking W and r, and illustrate it graphically. Show what happens to the FPF if general productivity increases.
