Unit 4: Monetary Policy

Answer: C — The correct answer is C. Both increasing the discount rate and selling government securities are contractionary monetary policy tools designed to reduce the money supply and lower inflation during periods of economic overheating. When the Fed raises the discount rate, banks borrow less and lend less to consumers and businesses. When the Fed sells securities, it removes money from the banking system. These actions work together to slow economic activity and reduce inflationary pressures. Option A represents the opposite strategy (expansionary policy). Option B is identical to C but placed at a different position to test careful reading. Option D misinterprets the Fed's objective—while higher rates do encourage saving, the primary goal here is inflation control through money supply reduction, not simply promoting savings behavior.

Answer: C — The correct answer (C) identifies the fundamental structural problem: when financial intermediaries themselves are damaged and deleveraging, they cannot transmit monetary stimulus through lending even when the Fed supplies liquidity. This reflects the impaired credit channel—a key distinction in post-2008 monetary theory. Option A is partially correct but incomplete; while bank unwillingness was part of the problem, it doesn't fully capture the systemic balance sheet deterioration. Option B represents a misconception about QE mechanics—the Fed's purchases actually increased the monetary base. Option D incorrectly suggests the zero lower bound made policy 'completely ineffective'; the Fed still had tools (QE, forward guidance) even if traditional rate cuts were exhausted. Understanding why monetary policy can fail despite aggressive action requires recognizing institutional constraints on credit transmission, not just interest rate mechanisms.

Answer: C — The correct answer (C) reflects a fundamental principle of monetary policy: transmission lags. Policy changes take considerable time to affect real economic variables like inflation because they must work through multiple channels (bank lending, investment decisions, wage-setting behavior, etc.). A researcher observing only short-term outcomes would miss the delayed effects. Option A represents a misconception about policy immediacy and misunderstands how complex economies function. Option B incorrectly identifies the discount rate as the most powerful tool (open market operations are primary) and assumes instantaneous effects. Option D reverses the expected relationship and ignores the distinction between monetary expansion in different economic conditions (during slack vs. demand-pull inflation). This question tests the student's ability to apply knowledge of policy transmission mechanisms to evaluate real-world policy assessments.

Answer: B — B is correct because it accurately traces the transmission mechanism: lowering the discount rate reduces the cost of borrowing reserves for banks, which increases their incentive to lend. Lower lending rates then encourage businesses and consumers to borrow for investment and consumption, expanding aggregate demand and economic activity. This reflects the actual sequential process by which monetary policy affects the real economy. A is incorrect because it confuses the direction of inflation (more money does not automatically decrease inflation—it typically increases it) and oversimplifies by ignoring time lags. C reflects the crude quantity theory misconception that money supply changes mechanically translate to proportional price changes with no real effects; in reality, monetary policy affects output and employment in the short run. D misrepresents consumer behavior and ignores the primary mechanism—instead of saving, consumers and businesses respond to lower rates by borrowing and spending, not by anticipating future rate increases.

Answer: B — The correct answer is B) The money supply increases, and interest rates fall. When the Fed purchases government securities in the open market, it injects more money into the economy, increasing the money supply. This excess liquidity reduces the demand for bonds, causing interest rates to fall. This expansionary monetary policy action stimulates economic growth by increasing borrowing and spending.
