Review Questions

• How did Keynes’ ideas challenge classical economic theories during times of economic distress?
  • Keynes’ ideas challenged classical economic theories by suggesting that markets do not always self-correct and that prolonged unemployment could persist without government intervention. He argued that aggregate demand is crucial for economic stability, contradicting the classical view that supply would create its own demand. This perspective was particularly relevant during the Great Depression when traditional methods failed to revive economies across Europe.
• In what ways did Keynesian economics influence post-World War II economic policies in Europe?
  • Keynesian economics significantly influenced post-World War II economic policies in Europe by promoting government intervention as a tool to ensure full employment and stimulate growth. Many European nations adopted Keynesian principles, implementing welfare programs and public investment strategies aimed at rebuilding economies. This shift helped shape modern welfare states and established frameworks for managing economic cycles through active fiscal policies.
• Evaluate the long-term impact of Keynes’ theories on contemporary economic policy debates, particularly regarding government spending during recessions.
  • The long-term impact of Keynes’ theories on contemporary economic policy debates is profound, especially concerning the role of government spending during recessions. His emphasis on using fiscal policy to counteract downturns has remained relevant, influencing responses to economic crises such as the 2008 financial meltdown. Debates continue over the effectiveness of stimulus measures versus austerity; however, many policymakers still lean towards Keynesian solutions as a means to mitigate recession impacts and ensure economic recovery.
