Review Questions

• How did John Maynard Keynes' ideas challenge classical economic theories regarding market self-correction?
  • Keynes' ideas introduced the concept that markets do not always self-correct, particularly during economic downturns. He argued that without government intervention, economies could remain in prolonged periods of low demand and high unemployment. This was a significant departure from classical economics, which maintained that markets are efficient and can recover on their own without outside influence.
• Discuss the role of fiscal policy in Keynesian economics and how it can be used to manage economic cycles.
  • In Keynesian economics, fiscal policy plays a critical role in managing economic cycles by using government spending and taxation to influence overall economic activity. During recessions, Keynes advocated for increased government spending to boost aggregate demand and create jobs. Conversely, during times of economic boom, he suggested reducing spending or increasing taxes to cool down an overheated economy, ensuring balanced growth.
• Evaluate the long-term implications of Keynesian economics on modern economic policies and its relevance today.
  • Keynesian economics has had profound long-term implications on modern economic policies, emphasizing the need for government intervention in times of economic distress. Today, many governments still utilize Keynesian principles when crafting fiscal policies during recessions, such as stimulus packages or infrastructure spending. The relevance of these ideas continues as policymakers navigate challenges like unemployment and inflation, often relying on Keynes' insights to inform their decisions about managing the economy effectively.
