Consider the following function (a Cobb-Douglas production function): F (K, L) = AKL1-Q What is the partial derivative of F(K, L) with respect to K? In other words, what is the marginal product of capital? OF(K,L) = QAKa [1-a O OF(K, L) ak = (1 - Q) AK-151-a = (1 -Q) A( L) 1-a OF(K, L) OK = AKa-1L1-a = A(#) O OF(K,L) OK = Aaka-151-a = QA(*)
