Now suppose their school opens up a market for loanable funds in which students can borrow and lend among themselves at an interest rate  .

A student would choose to be a borrower in this market if his or her expected rate of return is ___(Less or Greater) than  .

Suppose the interest rate is 7 percent.

Among these three students, the quantity of loanable funds supplied would be $, and quantity demanded would be $

Now suppose the interest rate is 10 percent.

Among these three students, the quantity of loanable funds supplied would be $, and quantity demanded would be$

At an interest rate of , the loanable funds market among these three students would be in equilibrium. At this interest rate,(Harry, Hermione, Ron, Ron and Harry, Hermione and Ron) would want to borrow, and (Harry, Hermione, Ron, Ron and Harry, Hermione and Ron) would want to lend.

Suppose the interest rate is at the equilibrium rate.

Complete the following table with how much each student will have a year later after the investment projects pay their return and loans have been repaid.
