Supply-side economics

Review Questions

• How does supply-side economics propose to stimulate economic growth, and what are its main assumptions?
  • Supply-side economics suggests that economic growth can be stimulated by lowering taxes and reducing regulation. The main assumptions include the belief that lower tax rates provide incentives for businesses to invest more, increase production, and create jobs. It operates on the premise that if businesses thrive due to these incentives, the resulting increase in economic activity will benefit the entire economy, including workers and consumers.
• Discuss the potential criticisms of supply-side economics and how they relate to its impact on income inequality.
  • Critics argue that supply-side economics primarily benefits wealthy individuals and corporations, leading to greater income inequality. They contend that while tax cuts may promote investment, they often do not translate into proportional benefits for lower-income groups. Additionally, opponents point out that increased deficits resulting from lowered tax revenues could lead to cuts in essential public services, further exacerbating social inequities.
• Evaluate the effectiveness of supply-side economics in real-world applications, citing specific examples from different administrations.
  • The effectiveness of supply-side economics can be evaluated through its implementation during various administrations, such as Ronald Reagan's presidency in the 1980s. Advocates argue it successfully stimulated growth and lowered inflation; however, critics highlight rising deficits and income inequality during this period. Similarly, attempts at supply-side policies in subsequent administrations have led to debates on their overall impact on long-term economic stability versus short-term gains. Analyzing these real-world outcomes helps illustrate whether supply-side economics can achieve its intended goals without negative side effects.
