Exercises-Solow model 1. For A1 and O.5, redo the calculations of our numerical example; 2. For a saving rate of 20%, a depreciation rate of 10% and the function of production of the previous question. discover the optimal level of the stock of capital by doing a numerical simulation in Excel. 3. Evaluate the obvious implication of the Solow model that countries less simply need a higher savings rate. 4. For a sample of countries of the various types, find: A. savings rates b. the value of the capital stock per worker and per capita c. the net capital growth rate over 5 years d. the growth rate of GDP per worker and per capita over 5 years. 5. Consider a closed economy with a stable population and no progress technical. In the case where the cconomy has not reached a capital/labour ratio (K/N) stable (i.e. not in a stationary state), explain what must happen: A. If the current gear K=K/N is below the gear K in steady state equilibrium b. If the current ratio K=K/N is higher than K C.fllustrate your answers using graphs. Exercises-Solow model 1.
