Answer:
Supply curve for loanable funds would shift, leading to a fall in the equilibrium interest rate.
Step-by-step explanation:
If the people are convinced that saving is important and start saving more, the supply of loanable funds will increase. As a result the supply curve will shift to the right. This shift in the supply curve will be accompanied with a decline in the equilibrium interest rate.
So, the correct answer is: supply; downwards.
