这是一段经济学原理的英文,望大虾们帮忙翻译下,
To know which of these policies would be a more effective way to raise investment,you'dneed to know:(1)what the elasticity of private saying is with respect to the after-tax real interest rate,since that would determine how much private saving would increase if you reduced taxeson saving;(2)how private saving responds to changes in the government budget deficit,since,gor example,if Ricardian equivalence holds,the decline in the government budget deficit would be matched by an equal decline in private saving,so national saving wouldn't increase at all; and(3)how elastic investment is with respect to the interest rate,since if investment is quite inelastic,neither policy will have much pf an impact on investment.
要知道这些政策中哪个能更有效的提高投资,你需要知道:(1)个人储蓄的税后实际利率弹性是多少,因为这决定了降低储蓄所得税后人们将增加多少个人储蓄;(2)个人储蓄对于政府预算赤字的变化如何反应,例如,如果李嘉图等价定理成立的话,政府预算赤字的下降将和个人储蓄的下降相等,那么整个国家的储蓄将不会增加;(3)投资的利率弹性是多少,因为如果投资完全不具有弹性,那么任何政策都不会对投资产生影响.
