Fiscal Policy: Principles, Mechanisms, and U.S. Government Budget

Fiscal Policy

Introduction

Fiscal policy is a central topic in macroeconomics, focusing on how government spending and taxation influence the overall economy. This study guide covers the definition, mechanisms, and effects of fiscal policy, with a particular emphasis on the U.S. context.

What is Fiscal Policy?

Definition and Scope

• Fiscal Policy refers to changes in federal taxes and government purchases that are intended to achieve macroeconomic policy goals, such as stable growth, low unemployment, and controlled inflation.

• Economists typically restrict the term to actions by the federal government that affect the national economy.

Types of Fiscal Policy

• Automatic Stabilizers: Government spending and taxes that automatically increase or decrease with the business cycle, helping to moderate economic fluctuations without new legislative action.

  • Example: Unemployment insurance payments rise during recessions; tax revenues fall as incomes decline.

• Discretionary Fiscal Policy: Deliberate actions by the government to change spending or taxes.

  • Example: Tax rebates or stimulus payments enacted by Congress and the President.

Classifying Fiscal Policy Actions

• Increasing government spending on disaster recovery (e.g., rebuilding after a hurricane) is discretionary fiscal policy.

• Declining income tax revenue during a recession is an automatic stabilizer.

• Temporary payroll tax cuts enacted by Congress and the President are discretionary fiscal policy.

Government Budget

Structure of the Government Budget

• The government budget equals total revenue minus total expenditures.

• Revenue: Primarily comes from taxes (income, payroll, corporate, etc.).

• Expenditures: Consist mainly of government purchases (goods and services) and transfer payments (such as Social Security, Medicare, and unemployment benefits).

Government Expenditures and Revenues in the U.S.

Trends in Expenditures

• Government expenditures as a fraction of GDP have fluctuated over time, often rising during recessions or periods of crisis (e.g., financial crises, pandemics).

• Major components include consumption expenditures, transfer payments, and interest payments on debt.

Trends in Revenues

• Government revenues are primarily derived from taxes, which can vary with economic conditions.

• During recessions, revenues typically decline due to lower incomes and profits.

Year	Consumption Expenditures	Current Transfer Payments	Interest Payments
2020	Approx. $1.3 trillion	Approx. $3.5 trillion	Approx. $0.4 trillion
2021	Approx. $1.4 trillion	Approx. $3.7 trillion	Approx. $0.4 trillion
2022	Approx. $1.5 trillion	Approx. $3.8 trillion	Approx. $0.5 trillion

Learning Goals

• Identify whether a policy measure is fiscal policy, and if so, whether it is discretionary or an automatic stabilizer.

• Define fiscal policy and its macroeconomic goals.

• Analyze the effects of fiscal policy using the static and dynamic AD-AS models.

• Use multipliers to assess the impact of fiscal policy changes on real GDP.

• Understand basic facts about the U.S. government budget.

Key Terms and Concepts

• Aggregate Demand (AD): The total demand for goods and services in an economy at a given overall price level and in a given period.

• Automatic Stabilizer: A feature of fiscal policy that automatically changes government spending or taxes in response to economic conditions.

• Discretionary Fiscal Policy: Policy actions that are initiated by the government to influence the economy.

• Transfer Payments: Payments made by the government to individuals, primarily through social programs, without receiving goods or services in return.

• Government Purchases: Expenditures on goods and services that directly absorb resources.
