b. Use the Solow Model graph to explain and illustrate the followings (for this question, you do not have to have a long verbal explanation. An illustration with graphs and a short-answer will be sufficient): i. Why do some countries have a high level of national income and others have a low equilibrium level of national income, and they stay there? ii. Why doesn't a once-and-for-all injection of capital from outside of the economy help economy maintain a high level of national income in the long-run? Hint: After World War II, Japan made one-time war repatriations for some Asian countries, such as Korea, Indonesia, Philippines, and so forth. Show why this repatriation itself, either in money or capital, does not help those economies in the long-run
