What does Solow model predict about output. In this video I introduce the Solow growth model and show how to solve for the steady state.The steady state is the key to understanding the solo model. At the steady state investment is equal to depreciation. An increase in saving and investment raises the capital stock and thus raises the full-employment national income and product. Figure: Determination of the steady-state capital-labor ratio in the Solow model without population growth and technological change. Daron Acemoglu (MIT). Output and capital per worker grow at the same constant, positive rate in BGP of model. In long run model reaches BGP. 2. Theories of Economic Growth and Policy 2 A.
