Review Questions

• How does the marginal tax rate influence personal financial decisions regarding additional earnings?
  • The marginal tax rate directly impacts how much money individuals retain from their additional earnings. When considering taking on extra work or investments, knowing the marginal tax rate helps assess whether the after-tax income from those earnings is worth the effort. A higher marginal tax rate means more of that extra income goes to taxes, potentially discouraging individuals from pursuing higher earnings.
• Compare and contrast the marginal tax rate with the effective tax rate and discuss their relevance in understanding overall taxation.
  • The marginal tax rate focuses on the percentage taxed on the last dollar earned, while the effective tax rate represents the average taxation across all income. The marginal rate is essential for understanding how much additional income will be taxed, helping individuals make choices about work and investment. In contrast, the effective tax rate provides a broader perspective on how much of total income is paid in taxes, giving a sense of overall financial burden.
• Evaluate the implications of changes in marginal tax rates on economic behavior and government revenue.
  • Changes in marginal tax rates can significantly influence economic behavior by altering incentives for work, saving, and investing. For example, if marginal rates increase, individuals may decide to limit their work hours or invest less due to lower returns after taxes. Conversely, lower marginal rates might encourage more economic activity. These changes can impact government revenue; higher rates might reduce overall activity and collections, while lower rates could stimulate growth but potentially decrease revenue if not balanced correctly.
