1.If the money supply increases by 7 percent and the price level increases by 4 percent,then what is the change in nominal GDP and real GDP?
2.Suppose that you are the head of the central bank of your country and one of your main responsibilities is to maintain the price level at a constant value.
Using quantity equation,explain what you would do to the money supply in response to each of the following events:
a) Real GDP increases by 3 percent during an economic boom.
b) According to the country economic report prepared by the World Bank,real GDP will continue to grow at a rate of 4 percent per year.

我先讲一下原理,再给你解答,要不你也只是抄上.
　　费雪现金交易数量说：
　　费雪交易方程：MV=PY（M流通中的货币,V货币流通速度,P价格,Y总产出）
　　他认为：在短期内,V是稳定的,Y在一定时期内不变,价格的变动是由货币数量决定的,而且是同方向变动.（货币只有交易媒介功能）
　　对方程两遍同时对时间求导,我没可以得到如下方程
　　dM*V+dV*M=dP*Y+dY*P
　　两遍同时除以MV又因为MV=PY,所以右边是除以PY
　　dM/M+dV/V=dP/P+dY/Y
　　同时乘以一个单位的时间变量
　　可以得到
　　货币供给的变化率+货币流通速度的变化率=物价水平的变化率+实际国民收入的变化率=名义国民收入的变化率
　　现在假定货币流通速度不变就可以解答了
　　第二个问题涉及潜在产出和货币政策的刺激问题
　　以下是中文的解答
　　1.费雪交易方程
　　dM/M+dV/V=dP/P+dY/Y
　　问题给出的数据,我们得到
　　7%=4%+dY/Y
　　实际GDP提高了3个百分点,名义GDP提高了7个百分点
　　2.如果是两个问题就不一样了,我仅仅给出我个人的解答.你可以采用或否定.
　　A.实际GDP增长3%,同时又是在繁荣时期,要使物价水平不变,那么就要相应的增加高于3%的货币供给,这是因为在繁荣时期,交易量增加,货币的流通速度也会增加的,所以你应该以3%为最低的货币增长率,适当的增加货币供给.
　　B.假定世界银行的报告是正确的,那么你就要保证在预期GDP低于4%时,增加货币供给以刺激经济,预期GDP高于4%时减低货币供给,以保证经济的平稳发展和物价水平的不变.
　　1.According to Fisher transaction equation dM / M + dV / V = dP / P + dY / Y
　　substitute value of date that the problem provided,we can get
　　7%=4%+dY/Y
　　Thus,Real GDP increased by 3 percent,nominal GDP increased by 7 percent
　　2.According to World Bank data,the level of potential output growth should be 4%,while we only have 3% of the equilibrium outputs,so there is 1% ressetion gap,we should use monetary policy to stimulate economic,but your task is to maintain price stability,so you should increase the money supply 1% at the same time take measures to ensure the money supply will not affect the price level stability.
