: 想請教板上的大大....
: 小弟有一個經濟學的問題....
: 希望各位可以幫忙...
: 題目是有關經濟學的....
: 當政府降低租稅時,對稅率(i)及實質所得(Y)有何影響?(請以IS-LM曲線分析之)??
: 希望板上大大可以幫忙...
: 因為一直寫不出來...
: 謝謝
這種題目我個人建議自己上網找答案。不然就是提供一點誘因。請別人不動腦寫
問卷都會附個50, 100P幣了,這種要耗腦力的兩個字"謝謝"就結束,可能不是很
能讓人家有誘因回答。

按照慣例附連結。把文中內容擷取完畢,答案就出來了。
In a closed economy, the IS curve is defined as:
Y=C(Y-T)+I(r)+G, where Y represents income, C(Y-T)represents consumer spending
as a function of disposable income (income, Y, minus taxes, T),I(r) represents
investment as a function of the real interest rate, and G represents
government spending. In this equation, the level of G (government spending) and
T (taxes) are presumed to be exogenous, meaning that they are taken as a given.
Mathematically, the LM curve is defined as M / P = L(r,Y),
故事結束。T下降,Y上升。LM不動,IS 右移,名目利率上升。
至於稅率i怎麼動,我覺得既然降低了租稅,稅率應該是下降的。
