Solutions to Assignment 3 1. The per-capita production function is: y = Ak 1 = 3 The ratio of output in countries A and B is therefore given by: y a y b = A a A b ( k a k b ) 1 = 3 Plugging in y a y b = 1 : 5 and k a k b = 2 , we obtain A a A b = 1 : 19 . 2. There is no contradiction. The Solow model implies that the steady-state rate of growth of any country is independent of its rate of saving. However, out of steady-state, the rate of growth does depend on the rate of saving.

(a) The e¢ cient allocation of labor across sectors requires that the value of the marginal be the marginal product multipled by the price of the product. So if we have two sectors A and B, the condition for e¢ ciency is: P A MPL A = P B MPL B
