1. 1. The Federal Reserve's primary tool of monetary policy is:

   • A. Changing the discount rate
   • B. Open market operations (buying/selling government bonds)
   • C. Adjusting the reserve requirement
   • D. Setting the federal funds rate directly
   Show answer

   Correct answer: B. Open market operations (buying/selling government bonds)

   Open market operations run the show. The FOMC meets every six weeks and decides direction, then the New York Fed's trading desk buys or sells Treasury bonds to hit the target. Option A is used only rarely. Option C is largely historical; the Fed dropped reserve requirements to zero in March 2020. Option D is a common misconception. The FOMC sets a target range for the fed funds rate, and the trading desk uses OMOs to steer the actual market rate into that range.

2. 2. When the Federal Reserve buys government bonds in the open market, which of the following occurs?

   • A. Money supply decreases, interest rates rise, investment falls
   • B. Money supply increases, interest rates fall, investment rises
   • C. Money supply increases, interest rates rise, investment falls
   • D. Money supply decreases, interest rates fall, investment rises
   Show answer

   Correct answer: B. Money supply increases, interest rates fall, investment rises

   Expansionary operation. When the Fed buys bonds, it credits bank reserve accounts with new money. Those reserves multiply through lending as banks make loans, depositors hold the new funds, and other banks lend against those deposits. The expanded money supply pushes interest rates down, which makes borrowing cheaper. Business investment rises along with interest-sensitive consumer purchases like mortgages and car loans.

3. 3. Which of the following represents contractionary monetary policy?

   • A. The Fed buys government bonds
   • B. The Fed lowers the discount rate
   • C. The Fed raises the reserve requirement
   • D. The Fed decreases the federal funds rate target
   Show answer

   Correct answer: C. The Fed raises the reserve requirement

   Raising the reserve requirement locks up more bank deposits as idle reserves, which shrinks lending capacity and pulls money supply down. Contractionary. The other options all expand the money supply. Option A injects reserves. Option B makes emergency borrowing cheaper. Option D signals an expansionary stance, the opposite of contraction. Contractionary moves typically mean selling bonds, raising rates, or tightening reserve rules.

4. 4. Which of the following is NOT a function of the Federal Reserve?

   • A. Conducting monetary policy
   • B. Collecting federal income taxes
   • C. Regulating and supervising banks
   • D. Serving as lender of last resort to banks in crisis
   Show answer

   Correct answer: B. Collecting federal income taxes

   Tax collection belongs to the IRS, which is part of the Treasury Department, not the Fed. The Fed handles monetary policy, bank regulation, and emergency lending. The lender-of-last-resort function is why the Fed was created in 1913, specifically to prevent the kind of bank panics that had plagued the US in 1873, 1893, and 1907.

5. 5. The interest rate effect helps explain why aggregate demand slopes downward. According to this effect:

   • A. Higher price levels increase money demand, raising interest rates and reducing investment
   • B. Higher price levels reduce the real value of wealth, decreasing consumption
   • C. Higher price levels make domestic goods more expensive, reducing net exports
   • D. Higher price levels reduce business confidence, discouraging investment
   Show answer

   Correct answer: A. Higher price levels increase money demand, raising interest rates and reducing investment

   When the price level rises, households and firms need more money to conduct the same real transactions. Money demand shifts right, which pushes interest rates up. Higher interest rates discourage investment and interest-sensitive consumption, so real output falls. That's the textbook interest rate effect. Option B describes the wealth effect. Option C describes the exchange rate effect. All three effects together explain why the AD curve slopes downward.

6. 6. Suppose the required reserve ratio is 10% and a bank receives a new deposit of $10,000. What is the maximum amount by which the money supply can ultimately increase?

   • A. $1,000
   • B. $9,000
   • C. $90,000
   • D. $100,000
   Show answer

   Correct answer: D. $100,000

   Money multiplier = 1 / 0.10 = 10. Maximum increase = $10,000 × 10 = $100,000. That original deposit sits in the first bank, which holds $1,000 as required reserves and lends out $9,000. The next bank receives that $9,000, keeps $900, and lends $8,100. Each round loses 10% to required reserves. Summed to infinity, the expansion totals $100,000. Real-world multipliers tend to be smaller because banks hold excess reserves and cash leaks out of the banking system.

7. 7. During the 2008-2009 financial crisis, the Federal Reserve used quantitative easing (QE) after lowering the federal funds rate to near zero. Quantitative easing primarily involves:

   • A. Raising the reserve requirement to protect banks from failure
   • B. Large-scale purchases of long-term assets (e.g., Treasury bonds and mortgage-backed securities)
   • C. Directly providing cash loans to consumers and small businesses
   • D. Requiring banks to hold more capital as a percentage of assets
   Show answer

   Correct answer: B. Large-scale purchases of long-term assets (e.g., Treasury bonds and mortgage-backed securities)

   Quantitative easing steps in when conventional policy hits the zero lower bound. The Fed buys longer-dated Treasury bonds and mortgage-backed securities in huge quantities to push down long-term yields specifically. Regular OMOs work through short-term rates, but QE directly targets the long end of the curve. The Fed's balance sheet ballooned from under $1 trillion in 2007 to over $4 trillion by 2014 through these purchases. Option D describes bank capital requirements, which are a regulatory tool separate from monetary policy.

8. 8. A key limitation of monetary policy is the liquidity trap, which occurs when:

   • A. The money supply is too large to be managed effectively
   • B. Interest rates are so low that additional monetary expansion cannot stimulate investment
   • C. Banks refuse to lend to the government
   • D. The Federal Reserve loses its independence from Congress
   Show answer

   Correct answer: B. Interest rates are so low that additional monetary expansion cannot stimulate investment

   A liquidity trap happens when rates are already at or near zero and further expansion can't push them lower. People and firms become willing to hold any amount of new money because cash is essentially free to hold. The transmission from money supply to investment breaks down. Japan has dealt with this since the 1990s, and the US came close to it after 2008, which is precisely why the Fed had to invent quantitative easing. The key insight is that QE works through different channels than conventional policy; it targets longer-term rates and asset prices rather than short-term interest rates that are already at the floor.
