Money, The Price Level, and Inflation

Introduction

This chapter explores the nature and functions of money, the role of banks and the Federal Reserve System, and how these elements interact to influence the price level and inflation in the economy. Understanding these concepts is essential for analyzing macroeconomic policy and financial stability.

What Is Money?

Definition and Functions of Money

• Money is any commodity or token that is generally acceptable as a means of payment.

• Means of payment refers to a method of settling a debt.

• Money serves three main functions:

  • Medium of exchange: Used to facilitate transactions for goods and services.

  • Unit of account: Provides a standard measure for stating prices and comparing values.

  • Store of value: Can be held and used for future purchases.

Medium of Exchange

• A medium of exchange is an object accepted in exchange for goods and services.

• Without money, transactions would require barter, which is the direct exchange of goods and services.

• Barter is inefficient because it requires a double coincidence of wants—both parties must want what the other offers.

Unit of Account

• The unit of account function allows prices to be stated and compared easily.

• Money simplifies price comparisons across different goods and services.

Store of Value

• Money can be held over time and used for future transactions.

• This function allows individuals and businesses to save and plan for future expenditures.

Money in the United States Today

• Money consists of currency and deposits at banks and other depository institutions.

• Currency refers to notes and coins held by individuals and businesses.

• Notes and coins inside banks are not considered currency, as they are not in circulation.

• Deposits are considered money because they can be used to make payments.

Official Measures of Money

• The two main official measures of money in the United States are M1 and M2:

• M1: Currency plus demand deposits and other checkable deposits owned by individuals and businesses that can be withdrawn on demand.

• M2: M1 plus small-denomination time deposits and retail money market mutual funds.

What Is Not Money?

• Checks and debit cards are instructions to transfer money, not money themselves.

• Credit cards and mobile wallets are not money; they facilitate transactions but must be settled with money.

Depository Institutions

Definition and Types

• A depository institution is a firm that takes deposits from households and firms and makes loans to other households and firms.

• Main types:

  • Commercial banks: Licensed private firms that receive deposits and make loans.

  • Thrift institutions: Includes savings and loan associations, savings banks, and credit unions.

  • Money market mutual funds: Funds operated by financial institutions that sell shares and hold assets like U.S. Treasury bills.

Functions and Regulation

• The goal of banks is to maximize the wealth of their owners by lending at higher interest rates than they pay on deposits.

• Banks must balance profit and prudence, ensuring depositors can access their funds.

• Banks invest in three main types of assets:

  • Cash assets: Notes and coins in vaults or deposits at the Federal Reserve.

  • Securities: U.S. government Treasury bills, commercial bills, and bonds.

  • Loans: Commitments of money for agreed-upon periods.

• Depository institutions are regulated to minimize risk, required to hold reserves and capital above regulatory minimums.

• Deposits are insured up to $250,000 per depositor per bank by the FDIC (Federal Deposit Insurance Corporation).

The Federal Reserve System (The Fed)

Role and Structure

• The Federal Reserve System is the central bank of the United States.

• It regulates depository institutions and controls the quantity of money.

• The Fed's goals include keeping inflation in check, maintaining full employment, moderating the business cycle, and supporting long-term growth.

• The federal funds rate is a key interest rate for overnight loans between banks.

Structure of the Fed

• Board of Governors: Seven members appointed by the President, confirmed by the Senate, serving staggered 14-year terms. One member serves as chairman.

• Regional Federal Reserve Banks: Twelve regions, each with its own board and president.

• Federal Open Market Committee (FOMC): Main policy-making group, includes Board of Governors, president of the New York Fed, and four other regional presidents (rotating).

• The FOMC meets every six weeks to set monetary policy.

Policy Tools of the Fed

• Open market operations: Buying and selling government securities to influence bank reserves.

• Discount window and discount rate: Lending to banks at the discount rate, set by the Board of Governors.

• Interest on reserves rate: Interest paid to banks on reserves held at the Fed.

Conduct of Monetary Policy

Open Market Operations

• Purchasing government securities increases bank reserves and the money supply.

• Selling government securities decreases bank reserves and the money supply.

• Open market operations are the primary tool for influencing the quantity of money.

Discount Window and Discount Rate

• The discount window allows banks to borrow from the Fed as a last resort.

• The discount rate is the interest rate charged on these loans.

Interest on Reserves Rate

• Banks earn interest on reserves held at the Fed, both required and excess reserves.

• This rate is set by the Board of Governors and influences banks' willingness to lend.

How Banks Create Money

The Money Multiplier

• The money multiplier is the ratio of the change in the quantity of money to the change in the monetary base.

• Formula:

• Example: If the Fed increases the monetary base by $1 million and the quantity of money increases by $2.5 million, the money multiplier is 2.5.

The Money Market

Demand for Money

• The demand for money is the relationship between the quantity of money demanded and the nominal interest rate, holding other factors constant.

• The opportunity cost of holding money is the nominal interest foregone by not holding interest-earning assets.

• As the interest rate rises, the quantity of money demanded decreases; as the interest rate falls, the quantity demanded increases.

Supply of Money

• The supply of money is the relationship between the quantity of money supplied and the nominal interest rate, holding other factors constant.

• The quantity of money supplied is determined by the Fed and banks' plans to create currency and deposits.

Money Market Equilibrium

• Equilibrium occurs when the quantity of money demanded equals the quantity supplied.

• Short-run adjustments depend on the money supply regime.

• Long-run adjustments differ fundamentally from short-run adjustments.
