Chapter 14: Money and Its Functions

Definition of Money in Economics

Money is any asset that is generally accepted as a medium of exchange for goods and services. It serves as a standard unit of account, a store of value, and a means of deferred payment.

• Medium of Exchange: Money is used to facilitate transactions and eliminate the need for barter.

• Unit of Account: Money provides a common measure for valuing goods and services.

• Store of Value: Money can be saved and used for future purchases.

• Standard of Deferred Payment: Money is used to settle debts payable in the future.

Example: U.S. dollar bills are used to buy groceries, pay rent, and settle debts, illustrating all functions of money.

Liquidity and the Most Liquid Asset

Liquidity refers to how quickly and easily an asset can be converted into cash without significant loss of value. The most liquid asset is currency (cash) itself, followed by demand deposits (checking accounts).

• Most Liquid Asset: Currency (cash) is the most liquid because it is immediately spendable.

• Other Liquid Assets: Checking accounts, savings accounts, and money market funds (in decreasing order of liquidity).

Why Do People Hold Money?

• Transaction Motive: To make everyday purchases.

• Precautionary Motive: To cover unexpected expenses.

• Speculative Motive: To take advantage of future investment opportunities.

Dollar Bills in the Modern Economy

• Dollar bills serve as fiat money, meaning their value is not backed by a physical commodity but by government decree.

• They function as a medium of exchange and a unit of account.

Chapter 15: Monetary Policy and the Federal Reserve

What is Monetary Policy?

Monetary policy refers to the actions taken by a country's central bank (in the U.S., the Federal Reserve) to manage the money supply and interest rates to achieve macroeconomic objectives.

• Tools: Open market operations, discount rate, reserve requirements.

• Objectives: Control inflation, manage employment, stabilize the financial system, and promote economic growth.

Four Monetary Policy Goals of the Federal Reserve

• Price Stability: Keeping inflation low and predictable.

• High Employment: Striving for the natural rate of unemployment.

• Stability of Financial Markets and Institutions: Ensuring the financial system operates smoothly.

• Economic Growth: Promoting sustainable increases in real GDP.

Historical Policy Goals of the Federal Reserve

• 1913 (Founding): The main goal was to provide the nation with a safer, more flexible, and more stable monetary and financial system.

• 2007-2008 Financial Crisis: The Fed focused on stabilizing the financial system and providing liquidity to prevent a collapse of credit markets.

Federal Reserve Actions to Manage Monetary Policy

• Open Market Operations: Buying and selling government securities to influence the money supply.

• Discount Rate: Changing the interest rate charged to commercial banks for short-term loans.

• Reserve Requirements: Adjusting the amount of funds banks must hold in reserve.

Chapter 16: Fiscal Policy and Government Finance

Discretionary Fiscal Policy

Discretionary fiscal policy involves deliberate changes in government spending and taxation to influence economic activity.

• Examples: Stimulus packages, tax cuts, increased infrastructure spending.

Contractionary Fiscal Policy

Contractionary fiscal policy is used to slow down economic growth, typically during periods of high inflation. It involves decreasing government spending or increasing taxes.

• Purpose: Reduce aggregate demand and control inflation.

Fed Policy vs. Fiscal Policy

• Fed Policy (Monetary Policy): Managed by the Federal Reserve, focuses on money supply and interest rates.

• Fiscal Policy: Managed by the government, involves changes in taxation and government spending.

Objectives and Classification of Fiscal Policy

• Objective: Stabilize the economy by influencing aggregate demand.

• Classification: Can be expansionary (stimulate growth) or contractionary (slow growth).

Automatic Stabilizers

Automatic stabilizers are government programs that automatically increase or decrease with the business cycle, helping to stabilize disposable income and consumption.

• Examples: Unemployment insurance, progressive income taxes.

Federal Government Revenue and Expenditures (2022 and Forward)

The largest sources of federal government revenue and the order of expenditures are important for understanding fiscal policy.

Additional info: The order of expenditures may vary slightly by year, but Social Security, Medicare, and Medicaid are consistently the largest categories.

Government Transfer Payments

Transfer payments are payments made by the government to individuals without any goods or services being received in return. They are a major component of government spending.

• Examples: Social Security, Medicare, Medicaid, unemployment benefits.

Social Security

• Purpose: Provide income support to retirees, disabled individuals, and survivors of deceased workers.

• Type of System: Pay-as-you-go system, where current workers' taxes fund current beneficiaries.

• Problems Facing Social Security: Aging population, longer life expectancy, and a declining worker-to-beneficiary ratio threaten the system's long-term sustainability.

Additional info: The 2025 Fiscal Statement likely highlights the need for reform to ensure future solvency.

Medicaid and Medicare

• Medicaid: A joint federal and state program providing health coverage to low-income individuals and families.

• Medicare: A federal program providing health insurance to people aged 65 and older, and some younger people with disabilities.

Fiscal Policy Actions: Tax Cuts and Increases

• Tax Cuts (Expansionary): Designed to stimulate spending and economic growth during a recession by increasing disposable income.

• Tax Increases (Contractionary): Used to slow economic growth and control inflation by reducing disposable income and aggregate demand.

Key Formulas

• Government Spending Multiplier: where is the marginal propensity to consume.
