Review Questions

• How did Keynes's ideas challenge classical economic theories regarding employment and market self-regulation?
  • Keynes challenged classical economic theories by asserting that markets do not always self-correct efficiently and that prolonged periods of unemployment can occur without government intervention. He argued that during recessions, insufficient aggregate demand leads to unemployment, contrary to the classical belief that supply creates its own demand. This shift in thinking emphasized the importance of active government involvement to stimulate demand through fiscal policies.
• Discuss the role of government spending according to Keynesian economics and its impact on aggregate demand during economic downturns.
  • In Keynesian economics, government spending is viewed as a critical tool for boosting aggregate demand during economic downturns. Keynes believed that when private sector demand is insufficient, increased public expenditure can fill the gap and stimulate economic activity. This counter-cyclical approach suggests that effective fiscal policy can mitigate recessions by creating jobs, increasing consumption, and ultimately leading to recovery.
• Evaluate the long-term implications of Keynes's theories on modern fiscal policy and how they have shaped responses to recent economic crises.
  • Keynes's theories have had profound long-term implications for modern fiscal policy, particularly in how governments respond to economic crises. His advocacy for proactive fiscal measures has shaped responses to crises like the 2008 financial collapse and the COVID-19 pandemic. Policymakers increasingly rely on stimulus packages and increased public spending as tools to combat recessionary pressures, demonstrating the enduring relevance of Keynesian principles in addressing contemporary economic challenges.
