According to real business cycle theory, permanent and transitory shocks to technology should have very different effects on the economy. Use the parable of Robinson Crusoe to compare the effects of a transitory shock (good weather expected to last only a few days) and a permanent shock (a beneficial change in weather patterns). Which shock would have a greater effect on Crusoe's work effort? On GDP? Is it possible that one of these shocks might reduce work effort?
A.The population increased from 80 million to 90 million.
B.The population decreased from 75 million to 72 million.
C.The population decreased from 60 million to 50 million.
D.The population increased from 70 million to 80 million.
20世纪50年代美国经历了出生人数的大幅度增加,在70年代这个婴儿潮一代成为成年人并开始组织自己的家庭。
a.用居住投资模型预测,这一事件对住房价格和居住投资的影响。
b.计算20世纪70年代和80年代的住房的实际价格,这种价格用居住投资平减指数除以GDP平减指数来衡量。你发现了什么?这种发现与模型一致吗?(提示:一个好的数据来源是每年出版的《总统经济报告》(Economic Report of the President))
The United States experienced a large increase in the number of births in the 1950s. People in this baby-boom generation reached adulthood and started forming their own households in the 1970s.
a.Use the model of residential investment to predict the impact of this event on housing prices and residential investment.
b.For the years 1970 and 1980, compute the real price of housing, measured as the residential investment deflator divided by the GDP deflator. What do you find? Is this finding consistent with the model? (Hint: A good source of data is the Economic Report of the president, which is published annually)

表5-9反映了英国、法国、意大利的实际GDP与实际进口额的变化。
(1)用OLS对下列一元回归模型按国别估算,并计算决定系数R2、标准误差以及t值。
Y=α+βX+u
(2)关于计算出来的各国边际进口倾向,求95%的置信区间。
(3)当各国的实际GDP为以下数值时,计算实际进口额的预测值。
英国 X0=600
法国 X0=400
意大利 X0=150
(4)对(3)中的各项,计算实际进口额预测的置信区间。
表5-9 英国、法国、意大利的实际GDP与实际进口额 单位:10亿英磅;100亿法郎;10兆里拉
