- What are the three main tools the Federal Reserve uses to conduct monetary policy?
Show answer
Open market operations, the discount rate, and reserve requirements.- Define open market operations (OMO).
Show answer
The Fed's buying and selling of government securities and other financial assets to influence the monetary base and interest rates.- Reserve requirements | The percentage of deposits that banks must hold as reserves rather than lend out
Show answer
The percentage of deposits that banks must hold as reserves rather than lend out | Reserve requirements- What is the money multiplier and why does it matter?
Show answer
The money multiplier is the ratio of the money supply to the monetary base; it matters because it shows how initial Fed purchases expand the total money supply through credit creation.- Derive the formula for the simple money multiplier in terms of the reserve requirement ratio.
Show answer
Money multiplier = 1 / reserve requirement ratio. If RRR = 0.10, then multiplier = 10.- M1 definition
Show answer
The narrow money supply, consisting of currency in circulation plus checkable deposits (demand deposits and NOW accounts).- M2 definition
Show answer
The broader money supply, consisting of M1 plus savings deposits, money market accounts, and small time deposits (under $100,000).- The ____ is the interest rate at which commercial banks lend reserve balances to each other overnight.
Show answer
federal funds rate- Why does the Fed target the federal funds rate rather than set it directly?
Show answer
The Fed cannot set it directly because it is an interbank market rate; instead, the Fed uses open market operations to adjust the supply of reserves until the equilibrium rate matches the target.- Monetary transmission mechanism | The process through which changes in the money supply and interest rates affect real output and inflation
Show answer
The process through which changes in the money supply and interest rates affect real output and inflation | Monetary transmission mechanism- Describe the interest rate channel of monetary transmission.
Show answer
When the Fed lowers interest rates, borrowing becomes cheaper, so investment and consumption increase, raising output and inflation.- What is fractional reserve banking?
Show answer
A banking system in which banks hold only a fraction of deposits as reserves and lend out the remainder, thereby creating credit and expanding the money supply.- Required reserves vs. excess reserves: what is the difference?
Show answer
Required reserves are the minimum amount a bank must hold by law (based on reserve requirements); excess reserves are reserves held above this minimum.- The monetary base is ____.
Show answer
the sum of currency in circulation plus bank reserves held at the Federal Reserve- Central bank independence | Why is it considered important for monetary policy credibility?
Show answer
Central bank independence allows the central bank to pursue long-term price stability without short-term political pressure; credibility reduces inflation expectations and lowers the cost of disinflation.
