Review Questions

• Explain how the Keynesian perspective differs from the classical view on the role of government in the economy.
  • The Keynesian perspective emphasizes the importance of government intervention in managing aggregate demand to stabilize the economy and promote full employment. This contrasts with the classical view, which holds that the economy will automatically return to full employment equilibrium through the free market mechanism without the need for government intervention. Keynesian economists believe that during economic downturns, government fiscal and monetary policies can be used to stimulate aggregate demand and boost economic growth, whereas the classical view relies more on the self-correcting mechanisms of the free market.
• Describe the Keynesian perspective on the concept of a liquidity trap and its implications for economic policy.
  • The Keynesian perspective recognizes the possibility of a liquidity trap, a situation where interest rates are so low that monetary policy becomes ineffective, and the economy remains stuck in a recession. In a liquidity trap, Keynesian theory suggests that fiscal policy, such as government spending and tax cuts, can be more effective in stimulating aggregate demand and promoting economic recovery. This is because when interest rates are near zero, consumers and businesses may be reluctant to borrow and invest, even with lower rates, and instead prefer to hold cash. In this scenario, the Keynesian view emphasizes the need for the government to step in and directly boost aggregate demand through fiscal interventions.
• Analyze how the Keynesian perspective on the drivers of economic growth differs from the classical view, and explain the implications for economic policy.
  • The Keynesian perspective emphasizes the role of consumer spending and investment as the primary drivers of economic growth, rather than relying solely on the self-correcting mechanisms of the free market, as in the classical view. Keynesian economists believe that during economic downturns, the economy can get stuck in a state of underemployment equilibrium, where unemployment remains high due to insufficient aggregate demand. In this scenario, the Keynesian view suggests that government intervention through fiscal policy, such as deficit spending and tax cuts, can be used to stimulate aggregate demand and promote full employment. This contrasts with the classical view, which holds that the economy will automatically return to full employment equilibrium without the need for government intervention. The Keynesian perspective, therefore, has significant implications for economic policy, as it justifies a more active role for the government in managing the economy to achieve macroeconomic stability and promote economic growth.
