arabdopsis1

 According to new classical economists, is financing a reduction in current taxes by
government borrowing likely to result in an increase in:

aggregate demand? the real interest rate?
A. No                       No
B. No                      Yes
C. Yes                     No
D. Yes                    Yes

答案是A； 不increase aggregate demand 容易理解； 请问如何理解不增加real interest rate？ 多谢多谢

我个人理解是这样的，real interest rate的增加应该和市场上的money supply成反比，reduction in current taxes和government borrowing对市场上的money supply作用相抵消了，一个增加一个减少，所以real interest rate没有增加，不知道我这靠不靠谱啊，期待楼下有高人再讲解
