我只回总经题 =)
※ 引述《def345 (ting*2)》之铭言:
: 来源:研究所考
: 科目:经济学
: 问题:
: 1.古典模型中,技术进步会使劳动边际生产力上升.故名目工资上涨
: 我的想法:答案是给错的。我的想法是如果是P*MP(L)=W的话,MP(L)上升名目工资不
: 是也跟着涨嘛??
MPL = W/P is the laobr demand.
MPL goes up, together with the fixed labor supply, W/P goes up too,
i.e. real wage goes up.
: 2.an increase in US exports because of increasing foreign incomes is ____
: in the US
: (A)a decrease in induced expenditure
: (B)a decrease in automous expenditure
: (C)a increase in induced expenditure
: (D)a increase in automous expenditure
: 我的想法:答案是给D。我的想法是美国出口在国民所得恒等式里面不是有个X嘛??
: 为什麽是记在自发性支出呢??
In this case, EX is not a function of Y.
: 5.依照古典学派的可贷资金理论,
: (A)货币供给增加时利率下降
: (B)民间投资增加时利率下降
: (C)民间储蓄意愿降低时利率下降
: (D)贸易赤字增加利率下降
: (E)政府财政赤字减少时利率下降
Loanable fund market is about saving and investment.
Saving (vertical) is the supply and investment (I(r)) is the demand.
A Ms is not in the model.
B investment goes up, r goes up.
C saving goes down, r goes up.
D in a small open economy,r = r* (r* is the world interest rate.)
the difference in saving and investment is net export.
E budget deficit (T-G) goes down means governmnet saving goes up,
which leads to a higher interest rate.
: 我的想法:答案给E,我的想法是难道A选项没有嘛,货币供给增加造成货币超额供给
: 迫使利率下降,还是说可贷资金市场没有货币供给这个变数存在,抑或
: 因为货币是名目的所以不影响实质利率(可贷资金市场的利率是实质的??)
