Supply and demand for loanable funds The following graph shows the market for loanable funds in a closed economy. The upward-sloping orange line represents the supply of loanable funds, and the downward-sloping blue line represents the demand for loanable funds.

Scenario 1: Suppose savers either buy bonds or make deposits in savings accounts at banks. Initially, the interest income earned on bonds or deposits is taxed at a rate of 20%. Now suppose there is an increase in the tax rate on interest income, from 20% to 25%. Shift the appropriate curve on the graph to reflect this change. This change in the tax treatment of interest income from saving causes the equilibrium interest rate in the market for loanable funds to and the level of investment spending to Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital in the relevant time period. Suppose the government repeals a previously existing investment tax credit. Shift the appropriate curve on the graph to reflect this change. The repeal of the previously existing tax credit causes the interest rate to investment to Scenario 3: Initially, the…
