Supply-side economics

Definition

Review Questions

• How does supply-side economics propose to stimulate economic growth, and what are the main mechanisms behind this approach?
  • Supply-side economics proposes to stimulate economic growth by lowering taxes and reducing regulation. The main mechanisms behind this approach include providing tax incentives for businesses to invest in production capacity, thereby increasing job creation. It argues that as companies save on taxes, they will have more capital available for expansion and innovation, leading to overall economic growth.
• What are some potential criticisms of supply-side economics regarding its impact on income distribution and government budgets?
  • Critics argue that supply-side economics primarily benefits the wealthy, as tax cuts often favor high-income earners and corporations. This can exacerbate income inequality as wealth accumulates at the top. Additionally, if tax revenues decline without corresponding cuts in government spending, it can lead to budget deficits, undermining fiscal stability and essential public services.

  • The long-term effects of supply-side economics on economic performance have sparked significant debate. Supporters claim that policies from the Reagan era led to robust GDP growth and job creation.

This has led to calls for a reevaluation of tax policies to ensure a more equitable distribution of resources while maintaining economic vitality.
