Review Questions

• How did Keynes' theories challenge traditional views on market equilibrium and the role of government?
  • Keynes challenged the classical view that markets are self-regulating and always move toward equilibrium. He argued that during recessions, insufficient aggregate demand can lead to prolonged unemployment and economic stagnation. This belief prompted him to advocate for active government intervention through fiscal policies to stimulate demand, contrasting sharply with the idea that economies naturally correct themselves without any external influence.
• Discuss the implications of Keynesian economics on modern banking systems and their approach to financial crises.
  • Keynesian economics emphasizes the importance of government intervention during financial crises, influencing modern banking practices. In times of economic distress, banks often rely on government support or central bank policies aimed at increasing liquidity and stabilizing financial markets. This approach is rooted in Keynes' belief that maintaining confidence in the banking system is essential for restoring aggregate demand and preventing deeper recessions.
• Evaluate the impact of Keynes' ideas on the development of mixed economies and social welfare programs in the 20th century.
  • Keynes' ideas significantly shaped the development of mixed economies in the 20th century, where both private enterprise and government play crucial roles in economic management. His advocacy for social welfare programs arose from his belief that economic stability could be achieved by addressing social inequalities through government action. As a result, many countries adopted policies aimed at improving social welfare, reducing poverty, and regulating markets to ensure more equitable growth.
