The country of Kingsland is considering the introduction of a compulsory retirement saving scheme. Under this scheme all workers are required to save ten per cent of their annual wages and salaries until they retire. Use the supply and demand model (and a diagram) for saving and investment to explain the likely effects of this scheme on national saving, investment and the real interest rate in Kingsland. Explain the effects on employment of the saving scheme. (You can assume that Kingsland is a closed economy).
Since the level of national savings has increased, I understand how the savings curve shifts to the right and thus decreases the real interest rate and increases the levels of savings and investment in the economy. I am unable to understand how I can relate this back to the level of unemployment in the economy.
