Production Functions For each of the following show (a) if they are constant, increasing or decreasing returns to scale. (b) For each given factor, show if are they have increasing, decreasing or constant marginal returns. (c) What is the marginal return to capital and what is the marginal return to labor? "Show" means you should show why, not just yes or no. 1. F(K, L) = AKOL-a where 0 Sa $ 1 2. F(K, L, D) = AK-D L' 7-a where 0 Sa $1, 05731 3. F(K, L) = min(K, L) A. F(K, L) = OK + (1 -a) L where 0 5 a $ 1 5. F(K. L) = a log K + (1 -a) log L where 0 a $ 1
