假定货币需求函数的形式为 实际收入(Y)为500美元，名义利率为20％。货币供给固定在2500美元。 a．如果货币市场处于均衡状态，价格水平是多少? b．以横轴表示货币，画出货币供给函数和货币需求函数的图像。 i．用纵轴表示价格水平(Y=500，i=0．2)； ii．用纵轴表示利率(Y=500，P=2)； iii．用纵轴表示实际收入(P=2，i=0．2)。 在所有的图像中都要标出均衡点。 c．假定货币供给增加到5000美元。 i．如果通过价格水平进行调整，新的价格P应该是多少? ii．如果通过利率进行调整，新的利率i应该是多少? iii．如果通过实际收入进行调整。新的收入Y应该是多少? Assume a money demand function of the form .Real income(Y)is$500，and the nominal interest rate(i)is 20 percent．The money supply is fixed at$2，500． a．If the money market is in equilibrium，what is the price level? b．Depict the money supply and money demand functions in diagrams that have money in thehorizontal axis and i．the price level in the vertical axis(hold fixed Y=500 and i=0．2)． ii．the interest rate in the vertical axis(hold fixed Y=500 and P=2)． iii．the real income in the vertical axis(hold fixed P=2 and i=0．2)． Be sure to identify the equilibrium points in all the diagrams． C．Assume that the money supply doubles to$5，000． i．If the adjustment is through the price level，what is the new P? ii．If the adjustment is through the interest rate，what is new i? iii．If the adjustment is through real income，what is the new Y?
