Suppose the government borrows $20 billion more nest year than this year.

(b)   What happens to investment? To private saving? To public saving? To national saving? Compare the size of the changes to the $20 billion of extra government borrowing.

(c)    How does the elasticity of supply of loanable funds affect the size of these changes?

(d)   How does the elasticity of demand for loanable funds affect the size of these changes?

 

 

b问题是怎么分析出来的，我看答案说private saving 是增加的，为什么会是增加呢？？

还有c问题和d问题有什么区别么？？

 

望高手指点，千万个感谢～～～
