4. 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.
(Saving / Investment) is the source of the supply of loanable funds. As the interest rate falls, the quantity of loanable funds supplied (decreases / increases).
Suppose the interest rate is 3.5%. Based on the previous graph, the quantity of loanable funds supplied is (greater / less) than the quantity of loans demanded, resulting in a (surplus / shortage) of loanable funds. This would encourage lenders to (raise / lower) the interest rates they charge, thereby (increasing / decreasing) the quantity of loanable funds supplied and (increasing / decreasing) the quantity of loanable funds demanded, moving the market toward the equilibrium interest rate of ( ?% )
