2. Keynesian theory challenges the classical economic assumption of full employment equilibrium and argues that the economy can reach a state of underemployment equilibrium, requiring government intervention.
3. Keynesian economists believe that changes in aggregate demand, rather than changes in aggregate supply, are the primary drivers of economic fluctuations in the short run.
4. Keynesian fiscal policy emphasizes the use of government spending and tax policy to influence the level of economic activity and employment in the economy.
5. Keynesian theory suggests that government policies aimed at reducing trade deficits, such as tariffs or currency devaluations, can have a positive impact on the trade balance and overall economic performance.

Review Questions

• Explain how Keynesian economics relates to shifts in aggregate demand.
  • Keynesian economics emphasizes the role of aggregate demand in determining the level of economic activity and employment. According to Keynesian theory, when aggregate demand falls, the economy can reach a state of underemployment equilibrium, requiring government intervention through fiscal policy to stimulate demand. Keynesian economists believe that changes in aggregate demand, rather than changes in aggregate supply, are the primary drivers of economic fluctuations in the short run. Therefore, Keynesian policies aim to influence aggregate demand through government spending and tax policies to promote full employment and economic stability.
• Describe the relationship between Keynesian fiscal policy and the trade balance.
  • Keynesian theory suggests that government policies aimed at reducing trade deficits, such as tariffs or currency devaluations, can have a positive impact on the trade balance and overall economic performance. Keynesian economists believe that fiscal policy, including government spending and tax policy, can be used to influence the level of economic activity and employment in the economy. By stimulating aggregate demand through fiscal policy, Keynesian theory suggests that the government can potentially improve the trade balance by increasing domestic production and reducing the reliance on imports, while also boosting exports through a more competitive exchange rate.
• Evaluate the role of government intervention in the Keynesian economic framework and its implications for economic stability and growth.
  • The Keynesian economic framework emphasizes the importance of government intervention and active fiscal policy in stabilizing the economy and promoting full employment. Keynesian economists argue that the economy can reach a state of underemployment equilibrium, where aggregate demand is insufficient to maintain full employment. In this scenario, Keynesian theory suggests that government intervention through increased spending and reduced taxes can stimulate aggregate demand and boost economic activity. By actively managing fiscal policy, the government can influence the level of economic output, employment, and overall economic stability. This contrasts with the classical economic assumption of full employment equilibrium and the belief in the self-correcting nature of the market. The Keynesian approach has significant implications for the role of government in the economy and the potential for macroeconomic policies to promote economic growth and stability.
