Core concepts

Concept 2
Money market and loanable funds graphs use different interest-rate concepts.
Exam cue: Identify money market or loanable funds before shifting curves.

Memory anchors
Monetary Policy
Monetary policy uses central bank tools to influence money, credit, and interest rates.
Open Market Operation
Open market operations buy or sell securities to change reserves.
Discount Rate
The discount rate is the interest rate charged by the central bank for loans to banks.
Reserve Requirement
Reserve requirements set the fraction of deposits banks must hold.
Money Market
The money market shows money demand and money supply determining nominal interest rate.
Loanable Funds
The loanable funds market shows saving and borrowing determining real interest rate.
Crowding Out
Crowding out occurs when government borrowing raises interest rates and reduces private investment.
Interest Rate Effect
Higher interest rates reduce interest-sensitive spending.
Expansionary Monetary Policy
Expansionary monetary policy increases money supply and lowers interest rates in the simple model.
