Consider the Solow model with Y = AKL- as defined in the slides. If TFP increases by 6% whilst both K and L decrease by 4.5%, how much does Y change by? If the share of Labour in output has increased in equilibrium, what do you know must have happened to a? Consider an equilibrium path (=steady state path) in which TFP growth per year is 1% whilst population growth is 2% per year. Is it then true (or not) that capital per labour decreases over time? Is it true or not that capital-per-labour grows more quickly if the share of capital in output is higher?
