Define the following terms and explain their importance to the study of macroeconomics:
a. money
b. M1
c. near money
d. bank run
a. Money is the standard object used in the exchange of goods and services. Therefore, money serves as the medium of exchange. Changing the amount of money in circulation is a tool of macroeconomics, because money is a major determinant of aggregate demand.
b. M1 is the narrowest definition of the money supply. It is the sum of all coins and paper currency in circulation, conventional checking accounts, travelers' checks, and checkable deposits at banks and savings institutions. It consists of the most liquid (spendable) financial assets that can be used to make payments.
c. Near money is a liquid asset that is a close substitute for money. However, it is not nearly as spendable as the items in M1 . Some near monies include savings accounts and money market deposit accounts.
d. A bank run occurs when many bank depositors attempt to withdraw their funds all at once. This can pose a danger for banks in a fractional reserve system, because a bank usually does not have sufficient cash on hand to meet demands for withdrawals from all accounts.
