suppose Worry island is a closed economy.After the fincial turmoil,the households become pessimistic about the future.
a:instead,suppose the central bank targets on a fixed interest rate.Use the IS LM model to xplain how this would affect the interest rate and real output of Worry island/
b:A central bank can either targets on interest rate or money supply.Under the current condition of Worry island,which one should be chosen by the central bank as the policy target?why?
c:In reality,most of central bank prefer to target on interest rate to money supply.why?

假设Worry岛是个封闭的经济体,经过经济动荡,居民对未来不太乐观.
a：假设央行设定一个固定利率,用IS-LM模型来解释这将如何影响利率和实际产出?
b：假设央行可选择通过改变利率或货币供给的方式.在目前情形下,哪种方法应该作为政策目标?
c：实际上,大多数央行情愿选择改变利率而不是调整货币供给.为什么?
答：a中如果设定固定利率,则LM曲线为一条垂直线.此时财政政策完全有效.如果利率设置过低,会导致货币的投机需求很大,有可能会导致流动性陷阱.无论增加多少货币供给,都被人们储存起来,这将导致货币政策的失效.适当降低,从IS-LM曲线上看,利率降低,LM曲线右移,均衡点的Y值变大,即产出增加.调整货币供给不太好控制,因为货币乘数很大,基础货币的一点变动都会引起货币供应量的很大变化.因此通过利率调整方便
