3. Keynesian economists argue that in a liquidity trap, fiscal policy (government spending and taxation) may be more effective than monetary policy at boosting aggregate demand.
4. Central banks may resort to unconventional monetary policy tools, such as quantitative easing, to try to stimulate the economy during a liquidity trap.

Review Questions

• Explain how a liquidity trap relates to the Keynesian perspective on market forces.
  • The Keynesian perspective emphasizes the role of aggregate demand in driving economic outcomes, and a liquidity trap represents a situation where monetary policy becomes ineffective at boosting demand. In a liquidity trap, individuals and businesses prefer to hold cash rather than spend or invest, leading to a lack of demand and a stagnant economy. Keynesian economists argue that in such a scenario, fiscal policy may be more effective than monetary policy at stimulating the economy and increasing aggregate demand.
• Describe how a central bank might execute monetary policy in the context of a liquidity trap.
  • In a liquidity trap, traditional monetary policy tools, such as lowering interest rates, become less effective at stimulating the economy. Central banks may resort to unconventional policy measures, such as quantitative easing, to try to increase the money supply and encourage spending and investment. Quantitative easing involves the central bank purchasing government bonds or other financial assets from banks and the public, with the goal of injecting more liquidity into the financial system and lowering long-term interest rates. However, even these unconventional policies may have limited effectiveness in a liquidity trap, as individuals and businesses may still prefer to hold cash rather than spend or invest.
• Analyze how a liquidity trap can impact the outcomes of monetary policy and the broader economy.
  • In a liquidity trap, monetary policy becomes less effective at influencing economic outcomes, such as inflation and employment. With interest rates already at or near zero, further reductions in interest rates may have little impact on consumer and business spending. This can lead to a prolonged period of economic stagnation, with low inflation or even deflation, and high unemployment. The ineffectiveness of monetary policy in a liquidity trap may prompt central banks to resort to unconventional policy tools, such as quantitative easing, in an effort to stimulate the economy. However, even these measures may have limited success, as individuals and businesses may remain reluctant to spend or invest. In such a scenario, Keynesian economists argue that fiscal policy, such as increased government spending, may be more effective at boosting aggregate demand and promoting economic recovery.
