3. Will the result be a shortage or surplus in the loanable funds market at the original equilibrium?
4. Will lenders of existing fixed-rate loans be better or worse off as a result of the change in the real interest rate?
5. How will investment spending on facilities and equipment in this economy be impacted? Explain.
