宏观经济学试题及答案

一、名词解释 自动稳定器:亦称内在稳定器,是指经济系统本身存在的一种会减少各种干扰对国民收入冲击的机制,能够在经济繁荣时期自动抑制通胀,在经济衰退时期自动减轻萧条, 无需政府采取任何行动。 流动性陷阱:又称凯恩斯陷阱,指当利率极低,人们会认为这时利率不大可能再下降,或者说有价证券市场的价格不大可能再上升而只会跌落,因而人们不管有多少货币 都愿意持在手中,这种情况称为凯恩斯陷阱 货币投机需求:是指个人和企业为了抓住购买有价证券的机会以获利而产生的持币要求。国际收支均衡曲线:在其他有关变量和参数既定的前提下,在以利率为纵坐标,收入为横坐标的直角坐标系内,国际收支函数的几何表示即为国际收支曲线或称 BP曲线 奥肯定律:失业率每高于自然失业率1个百分点,实际GDP将低于潜在GDP2个百分点 生命周期消费理论:由美国经济学家莫迪利安尼提出,其核心理论在于,消费不单纯取决于现期收入,人们根据自己一生所能得到的劳动收入和财产,在整个生命 周期内平均安排消费,偏重对储蓄动机的分析 挤出效应:政府支出增加所引起的私人消费或投资降低的作用。扩张性财政政策导致利率上升,从而挤出私人投资,进而对国民收入的增加产生一定程度的抵消作用,这种 现象称为挤出效应。简单地说,挤出效应是指政府支出增加所引起的私人消费或 投资降低的作用 凯恩斯主义极端情形:是指IS曲线为垂直线而LM曲线为水平线的情况,这种情况下财政 政策非常有效,而货币政策完全无效 米德冲突:是指在许多情况下,单独使用支出调整政策或支出转换政策而同时追求内、外均衡两种目标的实现,将会导致一国内部均衡与外部均衡之间冲突 成本推进的通货膨胀:又称成本通货膨胀或供给通货膨胀,是指在没有超额需求的情况下由于供给方面成本的提高所引起的一般价格水平持续和显着地上涨 二、计算题 1、假定货币需求为L=0.2Y,货币供给为M=200,消费C=90+0.8Yd,税收T=50,投资I=140-5r,政府支出G=50,求: (1)均衡收入、利率和投资; 由c=90+0.8yd,t=50,i=140-5r,g=50和y=c+i+g可知 IS曲线为y=90+0.8yd+140-5r+50=90+0.8(y-50)+140-5r+50=240+0.8y-5r 化简整理得,均衡收入为y=1 200-25r ① 由L=0.20y,MS=200和L=MS可知(这里有点看不懂啊MS是什么啊?) LM曲线为0.20y=200,即y=1 000 ② 这说明LM曲线处于充分就业的古典区域,故均衡收入为y=1 000, 联立式①②得1 000=1 200-25r 求得均衡利率r=8, 代入投资函数,得i=140-5r=140-5×8=100 (2)若其他情况不变,政府支出G增加20,那么收入、利率和投资有什么变化? 在其他条件不变的情况下,政府支出增加20亿美元将会导致IS曲线发生移动,此时由y=c+i+g可得新的IS曲线为y=90+0.8yd+140-5r+70=90+0.8(y-50)+140-5r+70=260+0.8y-5r化简整理得,均衡收入为y=1 300-25r 与LM曲线y=1 000联立得1 300-25r=1 000 由此均衡利率为r=12,代入投资函数得i=140-5r=140-5×12=80 而均衡收入仍为y=1 000。 (3)是否存在“挤出效应”?
