Fiscal Policy

Introduction to Fiscal Policy

Fiscal policy refers to the use of government spending and taxation to influence the economy. It is a central tool for achieving macroeconomic objectives such as high and sustained economic growth and full employment.

• Federal Budget: An annual statement detailing the revenues, outlays, and surplus or deficit of the U.S. government.

• Purposes of the Federal Budget:

  • To finance the activities of the federal government

  • To achieve macroeconomic objectives

• Fiscal Year: A year that begins on October 1 and ends on September 30.

The Federal Budget

Budget Outcomes

• Budget Surplus: Occurs when government tax receipts exceed government expenditure.

• Budget Deficit: Occurs when government tax receipts are less than government expenditure.

• Balanced Budget: Occurs when government tax receipts equal government expenditure.

National Debt and Transfer Payments

• National Debt: The total amount of government debt outstanding, arising from past budget deficits.

• Transfer Payments: Payments such as Social Security, Medicare, Medicaid, and unemployment benefits provided to individuals and firms.

Sources of Tax Revenue

• Personal Income Taxes: Taxes on wages, salaries, and interest; the largest source of federal revenue.

• Social Security Taxes: Taxes paid by workers and employers to fund Social Security benefits; the second largest source.

• Corporate Income Taxes: Taxes on corporate profits; a smaller contributor.

• Sales and Excise Taxes: Indirect taxes such as sales, customs, and excise taxes; the smallest source of revenue.

Government Outlays

• Transfer Payments: The largest item on the spending side, including Social Security, Medicare, Medicaid, and unemployment benefits.

• Expenditure on Goods and Services: Includes defense and homeland security spending.

A Fiscal Policy Challenge

Demographic Pressures and Debt

The aging population, particularly the "baby boomers," presents a significant fiscal challenge as more individuals become eligible for Social Security and Medicare, increasing government obligations.

• By 2030, all baby boomers will be supported by Social Security and Medicare, doubling benefit payments.

• Social Security obligations are considered a form of government debt.

• Estimated in 2014: $68 trillion in obligations, growing by $2 trillion per year (Gokhale, The Government Debt Iceberg).

• In 2014, U.S. GDP was $17 trillion; thus, obligations equaled about 4 years of GDP.

Policy Alternatives to Address Fiscal Imbalance

• Raise income taxes

• Raise Social Security taxes

• Cut Social Security benefits

• Cut other federal government spending

To address the fiscal gap, a combination of these measures is likely required (e.g., raising income taxes by 69%, Social Security taxes by 95%, or cutting benefits by 56%).

Key Terms

• Fiscal Imbalance: The present value of the government's commitments to pay future benefits minus the present value of its future tax revenues.

• Generational Imbalance: The division of the fiscal imbalance between current and future generations.

• Fiscal Stimulus: An increase in government outlays or a decrease in tax revenue designed to boost real GDP and create or save jobs.

Fiscal Policy and Aggregate Demand

Impact on Aggregate Demand (AD)

Fiscal policy changes—whether in government spending or taxation—affect aggregate demand. These changes can be automatic (responding to economic conditions) or discretionary (resulting from legislative action).

• Any change in government budget items alters AD.

• These changes may occur automatically or through new policy decisions.

Types of Fiscal Policy

• Automatic Fiscal Policy: Built-in features that stabilize real GDP without explicit government action (e.g., unemployment benefits, progressive taxes).

• Discretionary Fiscal Policy: Policy actions initiated by Congress, such as changing tax rates or government spending.

Automatic Stabilizers

• Induced Taxes: Taxes that vary with real GDP, such as income taxes.

• Needs-Tested Spending: Spending that benefits qualified individuals or businesses and varies with real GDP (e.g., unemployment benefits).

Discretionary Fiscal Policy

• Initiated by legislative action (e.g., increasing defense spending, cutting income tax rates).

• Can involve changes in government outlays or tax revenues.

Budget Balances

• Structural Surplus/Deficit: The budget balance if the economy were at full employment.

• Cyclical Surplus/Deficit: The budget balance arising from deviations from full employment.

• The actual budget balance is the sum of the structural and cyclical balances.

Fiscal Policy Multipliers

Multiplier Effects

Changes in government spending or taxation have a multiplied effect on aggregate demand, meaning the total change in AD exceeds the initial policy change.

• Government Expenditure Multiplier: The effect of a change in government spending on goods and services on aggregate demand.

• Tax Multiplier: The magnification effect of a change in taxes on aggregate demand.

• Transfer Payment Multiplier: The effect of a change in transfer payments on aggregate demand.

• Balanced Budget Multiplier: The effect on aggregate demand of a simultaneous change in government purchases and taxes that leaves the budget unchanged.

Key Equations:

• Government Expenditure Multiplier: $\frac{1}{1 - MPC}$

• Tax Multiplier: $-\frac{MPC}{1 - MPC}$

• Balanced Budget Multiplier: $1$

Where MPC is the marginal propensity to consume.

Discretionary Fiscal Policy: Expansionary and Contractionary

Types of Discretionary Fiscal Policy

• Expansionary Fiscal Policy:

  • Reduces taxes

  • Increases government expenditure

  • Shifts aggregate demand to the right, increasing real GDP and the price level

• Contractionary Fiscal Policy:

  • Increases taxes

  • Reduces government expenditure

  • Shifts aggregate demand to the left, decreasing real GDP and the price level

Example: An increase in government spending during a recession is an expansionary policy, while a tax increase during inflation is contractionary.

Limitations of Discretionary Fiscal Policy

• Law-making Time Lag: The time required to pass new fiscal policy measures.

• Shrinking Area of Law-Maker Discretion: Many budget items are mandatory, limiting flexibility.

• Estimating Potential GDP: Difficulty in accurately measuring the economy's capacity.

• Economic Forecasting: Uncertainty in predicting future economic conditions.

Supply-Side Effects: Potential GDP and Growth

Supply-Side Effects of Fiscal Policy

Fiscal policy can influence the economy's productive capacity and long-term growth rate.

• An increase in government purchases that enhance productive services and capital raises potential GDP and aggregate supply (AS).

• A decrease in such purchases reduces potential GDP and AS.

Full Employment and Potential GDP

• When the quantity of labor demanded and supplied equals the full-employment quantity, real GDP equals potential GDP.

• Government budgets influence potential GDP through spending on public goods and services that enhance productivity.

Public Goods and Productivity

• Government expenditure on infrastructure, education, and technology can increase labor productivity and potential GDP.

Tax Wedge and Labor Market Effects

Tax Wedge

• The gap created by a tax between what a buyer pays and what a seller receives.

• In the labor market, it is the difference between the before-tax and after-tax wage rate.

Effects of Income Tax

• Taxes reduce the equilibrium quantity of labor employed, decreasing potential GDP.

• A tax cut increases aggregate demand (by boosting consumption) and increases potential GDP.

Supply-Side Effect of Taxes

• Taxes fund productive services and capital, but higher taxes can discourage work and investment, reducing potential GDP and AS.

• Lower taxes can incentivize work and investment, increasing potential GDP and AS.

Combined Demand and Supply Side Effects

Fiscal policy can simultaneously affect both aggregate demand and aggregate supply, influencing real GDP and the price level.

Long-Run Fiscal Policy Effects

• If budget deficits crowd out investment, economic growth slows and potential GDP declines.

• Persistent deficits increase debt, reduce confidence in the currency, and can lead to inflation.

• Controlling deficits and government outlays is essential for restoring a balanced budget at full employment.
