: 以下是一題是非題
: Suppose a tax cut affects both AD and AS. The larger is the supply-side
: effect of the tax cut, the larger is the increase in real GDP and the
: smaller is the increase in the price level.
: 答案是O
: 但我不懂的是 AS右移幅度比較大 應該P會下降不是嗎?
: 老師給的詳解是:"當減稅造成AS右移幅度大於AD右移幅度 則此時所得會增加越多
: 而物價會上漲越少"
: 我在想會不會是英文敘述解釋的問題,,,但我實在百思不得其解
: 還麻煩好心板
過了好多天了,不曉得你解出來沒,不過我還是把我的答案跟你分享:
首先,先畫出AD and AS curves, 然後將兩者均向右移,不過要把AS移多一點,看圖,你會發現equilibrium point向下一了一點,
然後你分別看X軸的變化量和Y軸的變化量,
X變化量就是the effect the tax cut has on real GDP.
Y變化量就是the effect the tax cut has on price level.
這樣看應該就看得出X變化量大於Y變化量(倘若看不出,建議你把AS右移多一點),
這樣一來,就得:the larger(effect) is the increase in real GDP and the smaller is the increase in price level.
hope this helps.
