Review Questions

• Explain how adjusting income tax rates can be used as a fiscal policy tool to fight recession and unemployment.
  • Lowering income tax rates can be used as a fiscal policy tool to stimulate the economy during a recession and help reduce unemployment. By increasing the disposable income of consumers and businesses, lower tax rates can lead to increased spending and investment, which can boost aggregate demand and economic growth. This, in turn, can create new job opportunities and help reduce the unemployment rate. Conversely, raising income tax rates can be used to cool an overheating economy and curb inflation by reducing disposable income and aggregate demand.
• Describe the role of the marginal tax rate in economic decision-making and its relationship to fiscal policy.
  • The marginal tax rate, which applies to the last dollar of income, is often more important for economic decision-making than the average tax rate. Individuals and businesses tend to base their economic decisions, such as investment and spending, on the marginal tax rate rather than the average rate. This is because the marginal tax rate directly affects the incentives and rewards for earning additional income. Governments can use changes in marginal tax rates as part of their fiscal policy toolkit to influence economic behavior and achieve policy objectives, such as stimulating investment or curbing inflation.
• Analyze how the progressivity of the tax system, with higher-income individuals paying a larger share of their income in taxes, can impact economic outcomes.
  • The progressivity of the tax system, where higher-income individuals pay a larger percentage of their income in taxes, can have significant implications for economic outcomes. A more progressive tax system can help reduce income inequality and redistribute wealth, which can promote social stability and economic growth. However, it can also reduce the incentives for high-income individuals to work, save, and invest, potentially dampening economic activity. Governments must carefully balance the trade-offs between equity and efficiency when designing the tax system as part of their fiscal policy approach to address economic challenges like recession, unemployment, and inflation.
