我只回總經題 =) ※ 引述《def345 (ting*2)》之銘言： : 來源:研究所考 : 科目:經濟學 : 問題: : 1.古典模型中，技術進步會使勞動邊際生產力上升．故名目工資上漲 : 我的想法:答案是給錯的。我的想法是如果是P*MP(L)=W的話，MP(L)上升名目工資不 : 是也跟著漲嘛?? 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：答案是給D。我的想法是美國出口在國民所得恆等式裡面不是有個X嘛?? : 為什麼是記在自發性支出呢?? In this case, EX is not a function of Y. : 5.依照古典學派的可貸資金理論， : (A)貨幣供給增加時利率下降 : (B)民間投資增加時利率下降 : (C)民間儲蓄意願降低時利率下降 : (D)貿易赤字增加利率下降 : (E)政府財政赤字減少時利率下降 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：答案給E，我的想法是難道A選項沒有嘛，貨幣供給增加造成貨幣超額供給 : 迫使利率下降，還是說可貸資金市場沒有貨幣供給這個變數存在，抑或 : 因為貨幣是名目的所以不影響實質利率(可貸資金市場的利率是實質的??) --
