Anything used as money – whether a deerskin, a barrel of oil, or a dollar bill – should fulfill the following four functions:  MEDIUM OF EXCHANGE  UNIT OF ACCOUNT  STORE OF VALUE  STANDARD OF DEFERRED PAYMENT

Glenn Hubbard, Anthony Patrick O’Brien CHAPTER 15: Money, Banks, and the Federal Reserve System 5 of 37 What Can Serve As Money? The five criteria of a suitable good as a medium of exchange.  The good must be acceptable to (that is, usable by) most traders.  It should be of standardized quality, so that any two units are identical.  It should be durable, so that value is not lost by spoilage.  It should be valuable relative to its weight so that amounts large enough to be useful in trade can be easily transported.  The medium of exchange should be divisible because different goods are valued differently. Fiat money: Money, such as paper currency, that is authorized by a central bank or governmental body and that does not have to be exchanged by the central bank for gold or some other commodity money.

Glenn Hubbard, Anthony Patrick O’Brien CHAPTER 15: Money, Banks, and the Federal Reserve System 6 of 37 How Do We Measure Money Today? M1: The Narrowest Definition of the Money Supply M1: The narrowest definition of the money supply: the sum of currency in circulation, checking account balances in banks, and holdings of traveler’s checks. It includes: 1.All the paper money and coins that are in circulation – meaning what is not held by banks or the government. 2.The value of all checking account balances at banks. 3.The value of traveler’s checks.

Glenn Hubbard, Anthony Patrick O’Brien CHAPTER 15: Money, Banks, and the Federal Reserve System 7 of 37 How Do We Measure Money Today? M2: A Broader Definition of Money M2: A broader definition of the money supply: M1 plus savings account balances, small-denomination time deposits, balances in money market deposit accounts in banks, and non-institutional money market fund shares. Two key points about the money supply to keep in mind are: 1.The money supply consists of both currency and balances in checking accounts and traveler’s checks. 2.Because balances in checking accounts are included in the money supply, banks play an important role in the process by which the money supply increases and decreases.
