: 想请教板上的大大....
: 小弟有一个经济学的问题....
: 希望各位可以帮忙...
: 题目是有关经济学的....
: 当政府降低租税时,对税率(i)及实质所得(Y)有何影响?(请以IS-LM曲线分析之)??
: 希望板上大大可以帮忙...
: 因为一直写不出来...
: 谢谢
这种题目我个人建议自己上网找答案。不然就是提供一点诱因。请别人不动脑写
问卷都会附个50, 100P币了，这种要耗脑力的两个字"谢谢"就结束，可能不是很
能让人家有诱因回答。
http://en.wikipedia.org/wiki/ISLM
按照惯例附连结。把文中内容撷取完毕，答案就出来了。
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),
故事结束。T下降，Y上升。LM不动，IS 右移，名目利率上升。
至於税率i怎麽动，我觉得既然降低了租税，税率应该是下降的。
