Substituting our expressions for k(t), L(t), and E(t) into dK = SAK L1-a - SK dt and using dK dk dE dL = EL + K L+ KE dt dt dt dt we obtain the capital accumulation equation for k: dk = SKY - (BE + 8L + 6) K . dtWrite out the steps need to show that the last equation on slide 21 of lecture 5 follows from the first equation on the same slide. Hint 1: A review of the first 2 pages of the memo has some helpful hints. Hint 2: the expression for k can be written as K = KEL
