Money, Monetary Policy, and Fiscal Policy: Key Concepts and Applications

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. In economics, money must fulfill specific functions to be considered as such.

• 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 retrieved in the future, retaining its value over time.

• 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, fulfilling all four 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.

• Most Liquid Asset: Currency (cash) is the most liquid asset because it is immediately accepted as payment.

• Other assets, such as stocks or real estate, are less liquid because they must be sold before they can be used for transactions.

Why Do People Hold Money?

• Transaction Motive: To make everyday purchases.

• Precautionary Motive: To have funds available for unexpected expenses.

• Speculative Motive: To take advantage of future investment opportunities or avoid losses from holding other assets.

Role of Dollar Bills in the Modern Economy

• Dollar bills serve as the medium of exchange in the U.S. economy.

• They are also a unit of account and a store of value.

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.

• Objectives include controlling inflation, managing employment levels, and stabilizing the financial system.

Four Monetary Policy Goals of the Federal Reserve System

• Price Stability: Keeping inflation low and stable.

• 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.

Main Policy Goal and Purpose of the Federal Reserve System in 1913

• The Federal Reserve was established in 1913 primarily to provide the nation with a safer, more flexible, and more stable monetary and financial system.

• Main Goal: To prevent banking panics and ensure financial stability.

Federal Reserve's Main Goal During the 2007-2008 Subprime Mortgage Crisis

• The Fed focused on stabilizing the financial system and preventing a collapse of major financial institutions.

• Actions included providing emergency lending and lowering interest rates.

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 borrowing from the Fed.

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

Summary Table: Monetary Policy Tools and Goals

Tool	Description	Goal
Open Market Operations	Buying/selling government bonds	Control money supply, interest rates
Discount Rate	Interest rate for bank borrowing from Fed	Influence lending, liquidity
Reserve Requirements	Minimum reserves banks must hold	Control bank lending capacity

Chapter 16: Fiscal Policy

Discretionary Fiscal Policy

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

• Examples include stimulus packages or tax cuts enacted by Congress.

Contractionary Fiscal Policy

Contractionary fiscal policy is used to reduce aggregate demand, typically by decreasing government spending or increasing taxes, to control inflation.

• Example: Raising income taxes to slow economic growth.

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 (Congress and the President), focuses on government spending and taxation.

Fiscal Policy: Objective and Classification

• Objective: To influence macroeconomic conditions, including aggregate demand, employment, and inflation.

• Classified as: Either expansionary (to stimulate the economy) or contractionary (to slow the economy).

Automatic Stabilizers

Automatic stabilizers are government programs that automatically increase or decrease with the business cycle, without new legislative action.

• Examples: Unemployment insurance, progressive income taxes.

Largest Sources of Federal Government Revenue (2022 and Forward)

• Individual Income Taxes

• Payroll Taxes (for Social Security and Medicare)

• Corporate Income Taxes

• Other sources (excise taxes, tariffs, etc.)

Order of Federal Expenditures in 2022

• Social Security

• Medicare

• Medicaid

• Defense

• Other mandatory and discretionary spending

Government Transfer Payments

Transfer payments are payments made by the government to individuals without any goods or services being received in return.

• Examples: Social Security, unemployment benefits, welfare programs.

Social Security

• Purpose: To 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 fewer workers per retiree threaten long-term sustainability.

Additional info: The 2025 Fiscal Statement likely discusses projected shortfalls and the need for reform.

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 Cut to Stimulate Spending: Reducing taxes increases disposable income, boosting consumer spending and aggregate demand during a recession.

• Tax Increase to Slow Growth: Raising taxes reduces disposable income, decreasing spending and aggregate demand to control inflation.

Key Fiscal Policy Formulas

• Government Spending Multiplier:

$\text{Multiplier} = \frac{1}{1 - MPC}$

• Tax Multiplier:

$\text{Tax Multiplier} = -\frac{MPC}{1 - MPC}$

Where MPC is the marginal propensity to consume.
