可贷资金的供给曲线（Supply curve of loanable funds）

What determines the supply of loadable funds？ The demand for loadable funds？ What might cause the supply or demand for loadable funds to shift, and how would that affect interest rates？

响。假设经济中有两种类型投资：企业投资和居民投资，而且，假设政府只对企业投资制定了投资税减免。

a．这种政策如何影响企业的投资需求曲线？如何影响居民的投资需求曲线？

b．画出这个经济可贷资金的供给和需求曲线。这个政策如何影响可贷资金需求的供给？均衡利率会发生什么变化？

c．比较原来的均衡与新均衡。这种政策如何影响总投资量？如何影响企业投资量和居民投资量？

When the government subsidizes investment, such as with an investment tax credit, the subsidy often applies to only some types of investment. This question asks you to consider the effect of such a change. Suppose there are two types of investment in the economy: business investment and Residential investment. And suppose that the government institutes an investment tax credit only for business investment.

a．How does this policy affect the demand curve for business investment？ The demand curve for residential investment？

b．Draw the economy's supply and demand for loanable funds. How does this policy affect the supply and demand for loanable funds？ What happens to the equilibrium interest rate？

c．Compare the old and the new equilibrium. How does this policy affect the total quantity of investment？ The quantity of business investment？ The quantity of residential investment？
