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??) --
