題目是
In the Keynesian model in the long run, an increasing in taxes causes the
price level to _____ and the real interest rate to _____.
(A)fall;rise
(B)fall;fall
(C)rise;rise
(D)rise;fall
我選(B) 理由是因為tax增加,在AS-AD model 中, AD(G-T)會下移
所以P會下降
然後在IS-LM model 中
因為Tax增加 所以IS(G-T)下移 r下降
可是答案是(A)....
解答的理由是 在凱因斯學派中,政府的減稅政策會將低總合需求,使得AD線左移
造成社會物價水準下降;而根據費雪方程式,物價水準的下降又會
導致實質利率的提高 故答案為(A)
奇怪這題不是問increasing tax嗎 = =? 跟減稅有什麼關係
而且就算減稅 應該會使'政府收入減少吧...怎麼會使AD左移= =
完全看不懂解答再寫啥@@"
有兩個盲點 1.題目明明就問增稅
2.減稅AD會左移??
請大大們幫我解惑一下.. 感謝!!
