Review Questions

• How does Keynesian economics explain the relationship between government spending and economic recovery?
  • Keynesian economics posits that increased government spending can directly stimulate aggregate demand during economic downturns. By injecting funds into the economy through various public projects or social programs, the government creates jobs and increases income for individuals. This rise in income leads to greater consumer spending, which further boosts demand for goods and services, facilitating a cycle that helps to pull the economy out of recession.
• Evaluate the effectiveness of fiscal policy tools recommended by Keynesian economics in stabilizing an economy during a recession.
  • Fiscal policy tools like increased government spending and tax cuts are central to Keynesian economics. During a recession, these measures are thought to be effective in stimulating demand when private sector spending is insufficient. However, critics argue that such policies may lead to budget deficits or public debt. The effectiveness often depends on timely implementation, the magnitude of spending, and public confidence in recovery.
• Analyze how Keynesian economics addresses potential limitations in classical economic theories regarding market self-correction.
  • Keynesian economics challenges classical theories that assert markets are always efficient and self-correcting. While classical theories suggest that economies naturally return to full employment without intervention, Keynes argued that prolonged periods of unemployment can occur due to inadequate demand. This viewpoint suggests that without active government intervention, economies can remain stuck in a downturn for extended periods, highlighting the necessity for policies that actively stimulate demand to encourage recovery.
