这是一段经济学原理的英文,望大虾们帮忙翻译下,谢谢~
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.
