2. Keynesians believe that prices and wages are sticky, meaning they do not adjust quickly to changes in supply and demand, necessitating government intervention.
3. The multiplier effect is a key concept in Keynesian economics, suggesting that an initial increase in spending can lead to a larger overall increase in economic activity.
4. During recessions, Keynesian economists advocate for expansionary fiscal policy, which includes increased public spending and tax cuts to stimulate demand.

Review Questions

• How does Keynesian Theory explain the role of government intervention during economic downturns?
  • Keynesian Theory asserts that during economic downturns, aggregate demand falls, leading to increased unemployment and reduced output. To counteract this, the theory advocates for government intervention through fiscal policies such as increased public spending and tax cuts. By stimulating demand, the government can encourage consumer spending and investment, helping to boost the economy back towards full employment.
• Analyze how the multiplier effect is utilized in Keynesian Theory to promote economic recovery.
  • In Keynesian Theory, the multiplier effect is crucial as it illustrates how an initial increase in government spending can lead to a more significant overall increase in national income. For example, when the government invests in infrastructure projects, it creates jobs, which then increases income for workers. This income leads to higher consumer spending in the economy, generating further income and production. Therefore, understanding the multiplier effect helps policymakers gauge the potential impact of their fiscal interventions.
• Evaluate the criticisms of Keynesian Theory concerning its effectiveness during long-term economic challenges.
  • Critics of Keynesian Theory argue that its reliance on government intervention may lead to inefficiencies and distortions in the market. They contend that prolonged fiscal stimulus can result in increased public debt without delivering sustainable growth. Additionally, some economists assert that during certain conditions like a liquidity trap, traditional Keynesian measures may become ineffective as individuals hoard cash rather than spend it. Evaluating these criticisms highlights the ongoing debate about the appropriate balance between market forces and government involvement in addressing long-term economic challenges.
