The Money Supply Model • Money = Currency plus checkable deposits: M1 M = C + D • The monetary base (MB)—the assets of the central bank— “backs” the money supply • The CB’s assets = MB =The CB’s liabilities = C + R • The Fed controls the monetary base (MB) better than it controls reserves … but it doesn’t perfectly control MB MB = MBn + BR • The money supply (M) is a multiple m of the monetary base M = m x MB = m x (MBn + BR)
Factors that AffectThe Money Multiplier • Changes in the required reserve ratio r • The money multiplier and the money supply are negatively related to r • Changes in the currency ratio c • The money multiplier and the money supply are negatively related to c • Changes in the excess reserves ratio e • The money multiplier and the money supply are negatively related to the excess reserves ratio e • The excess reserves ratio e is negatively related to the market interest rate • The excess reserves ratio e is positively related to expected deposit outflows
