Federal Deficits and the National Debt

By the end of this section, you will be able to:
- Explain the U.S. federal budget in terms of annual debt and accumulated debt.
- Understand how economic growth or decline can influence a budget surplus or budget deficit.

The federal budget encompasses two key components: revenue (taxes) and expenditure (spending).
The annual budget deficit or surplus is defined as the difference between tax revenue collected and government spending within a fiscal year, which runs from October 1 to September 30 of the following year.

Budget Surplus: Occurs when tax revenue exceeds government spending.
Budget Deficit: Occurs when government spending exceeds tax revenue.
Historical Context:
  - The pattern of annual federal budget deficits and surpluses has been tracked since 1930 as a percentage of GDP.
  - Significant deficits were recorded during:
    - World War II
    - The 1930s
    - The 1980s
    - The early 1990s
    - The 2008-2009 recession.
  - The federal government has predominantly run budget deficits, with a short-lived surplus in the late 1990s before returning to deficit in the early 2000s and deeper deficits during the 2008-2009 recession.

The national debt represents the total amount the government has borrowed over time.
Annual Deficit vs. National Debt:
- The budget deficit refers to how much the government has borrowed in a specific year, while the national debt is the sum of all annual deficits and surpluses over time.
Debt/GDP Ratio Trends (1940-2014):
  - Post-1970s, the debt/GDP ratio exhibited distinct trends:
    - Large deficits in WWII raised the ratio significantly.
    - From the 1950s to the 1970s, surpluses or small deficits led to a declining ratio.
    - Significant deficits in the 1980s and early 1990s caused the ratio to rise sharply.
    - Surpluses from 1998 to 2001 resulted in a declining debt/GDP ratio.
    - The 2008-2009 recession caused a noticeable increase in the debt/GDP ratio due to rising deficits.

Factors Influencing Budget Deficits and Surpluses:
  - The gap between government spending and taxes determines the budget deficit/surplus.
  - The recession starting in late 2007 led to higher spending and lower taxes, resulting in a substantial deficit in 2009.
  - Government Spending Trends (1990-2014):
    - Declined steadily through the 1990s due, in part, to reduced defense spending and lower interest payments.
  - Tax Revenues:
    - Increased dramatically in the late 1990s, rising from 18.1% of GDP in 1994 to 20.8% in 2000 due to significant economic growth.
    - Factors contributing to tax revenue booms included:
      - Increases in personal income due to economic growth, leading to higher personal income taxes.
      - Increased payroll taxes due to higher employment levels.
      - Rising corporate profits resulting in higher corporate income taxes.
    - On the expenditure side, reduced government spending on transfer payments occurred due to increased employment rates.

Forecasting Long-term Deficits:
  - Predictions indicate that large deficits may recur due to the demographic shift following the baby boom—an increase in the proportion of elderly Americans.
  - By 2030, one in five Americans will be over age 65.
  - Projected combined spending on Medicare and Social Security is expected to rise from 8.3% of GDP in 2009 to approximately 20% by 2080 without an increase in tax revenues.
Future Options to Address Budget Deficits:
  - Options to balance projected spending increases could include:
    1. Increasing taxes substantially.
    2. Cutting spending dramatically in other areas.
    3. Raising the retirement age and/or increasing the age for receiving Medicare benefits.
    4. Accepting and managing large budget deficits.
Other suggestions include adjusting payroll tax caps to affect higher-income earners and conceptualizing Social Security and Medicare as programs where workers save for their retirement and healthcare.
The United States faces challenges similar to many European nations and Japan regarding maintaining promised benefits for an aging population amidst a declining proportion of workers.

In the next module, the discussion will shift to fiscal policy tools used to counteract business cycle fluctuations.
The upcoming content will also cover proposals for maintaining a balanced budget, ensuring government spending and taxes are equal annually.
Considerations on how government borrowing influences national saving, economic growth, and trade imbalances will also be included.
