Answer the questions below:
(A)Some argue that Japan's saving rate is too high. Suppose all Japanese citizens decide to save at a lower rate. Show what happens in this case in the saving and investment diagram where the S/Y curve shifts.

Illustrate the effect on the interest rate using the saving-investment approach and the four-diagram approach in parts (A) and (B). What happens to the four shares of GDP?
