关于宏观经济学的问题（高分悬赏）
1. Suppose real GDP is growing 3 percent, the money supply is growing at 10 percent, the velocity of money is constant, and the real interest rate is 5 percent.
a. What is the current inflation rate and nominal interest rate?
b. If the money supply growth rate increases to 15 percent, how will your answers in part (a) change?
c. If you were an investor, how would the change in the money supply growth affect your real profitability, assuming that you now receive the new nominal interest rate?
d. Based on your previous answers, would you prefer a fixed or a floating interest rate on your investments? Which would you prefer if you thought the money supply growth was going to be reduced?
可以用中文回答，谢谢，回答好的另加分！
a 通涨率=货币增长率10%-产量增长率3%+v货币流通速率
其中v等于名义收入和货币量之比
b 货币增长率换成15%
c 货币供给增加了,就是利率降低了,会鼓励投资，如果我是投资者,我会选择增加投资.
d 利率浮动还是固定,作为投资者的我来说,要看实际利率是下降还是提高了,才能决定是增加还是减少投资.
如果我确定货币供给会减少,我想我更愿意接受固定利率.因为如果是浮动利率,那么减少货币供给,就意味着利率升高,投资的成本回增加.
...试试看.
