23
Bond market terms
bond: certificate of indebtedness that specifies the obligations of the borrower to the buyer of the bond dat of maturity: time at which the loan will be repaid principal: promise of interest and eventual repayment of the amount borrowed term: length of time until the bond matures Perpetuities: bonds that never mature credit risk: probability that the borrower will fail to pay some of the interest or principal default: failure to pay tax treatment: way the tax laws treat the interest earned on it Municipal bonds: bond owners are not required to pay federal income tax on interest income (may not need to pay state and local taxes either) inflation protection: Treasury inflation-protected securities (TIPS) generally pay lower interest rate than similar ones without this feature
24
Stock market
stock: represents partial ownership in a firm and is a claim to some of the profits firm makes equity finance: sale of stock to raise money debt finance: sale of bonds stock index: computed as an average group of stock prices
25
Financial intermediaries
financial institutions through which savers can indirectly provide funds to borrowers
26
Banks
primary job: take in deposits from people who want to save and use these deposits to make loans to people who want to borrow medium of exchange: checks, electronic payment, debit card store of value: wealth that people have accumulated in past saving
27
Mutual funds
institution that sells shares to the public and uses the proceeds to buy a selection, to portfolio, of various types of stocks, bonds, or both stocks and bonds allow people with small amounts of money to diversify their holdings funds give ordinary people access to the skills of professional money managers index funds: buy all stocks in a stock index, perform somewhat better on average than mutual funds
28
Identity
equation that must be true because of the way the variables in the equation are defined
29
closed vs. open economy
closed: one that does not interact with other economies open: interact with other economies around the world
30
closed economy GDP equation
Y = C + I + G total income: (Y - C - G) S = I -> S = Y - C - G or S = (Y - T - C) + (T - G)
31
National saving
total income in the economy that remains after paying for consumption and government purchases
32
Private saving
amount of income that households have left after paying their taxes and paying for their consumption Y - T - C
33
Public saving
amount of tax revenue that the government has left after paying for its spending T - G -> positive: surplus negative: deficit
34
Investment
refers to the purchase of new capital, such as equipment or buildings
35
Saving
depositing unspent income in a bank or using it to buy some stock or a bond from a corporation
36
Market for loanable funds
all savers deposit their saving in this market, and all borrowers take out their loans there income people have chosen to save and lend out rather than use for their own consumption and to the amount that investors have chosen to borrow to fund new investment projects
37
Supply of loanable funds
saving is the source of the supply of loanable funds
38
Demand for loanable funds
investment is the source of the demand for loanable funds
39
Affect of higher interest rate
encourage saving (increasing the quantity of loanable funds supplied) and discourage borrowing for investment (decreasing the quantity demanded)
40
Impact of tax laws
reform of the tax laws encourages great saving, the result is lower interest rates and greater investment
41
Investment tax credit
tax reform aimed at making investment more attractive gives tax advantage to any form building a new factory or buying a new piece of equipment does not affect the supply of loanable funds demand for loanable funds moves to the right encourages greater investment, the result is higher interest rates and greater saving
42
Government debt and balanced budget
debt: accumulation of past government borrowing balanced: government spending exactly equals tax revenue
43
Crowding out
government borrows to finance its budget deficit, crowds out private borrowers who are trying to finance investment
44
Affect of reducing national saving
when government reduces national saving by running a budget deficit, interest rate rises, and investment falls long-run growth: government budget deficits reduce economy's growth rate
45
Affect of budget surplus
increases the supply of loanable funds, reduces the interest rate, and stimulates investment higher investment = greater capital accumulation and more rapid economic growth
46
Money
set of assets in the economy that people regularly use to buy goods and services from each other
47
Three functions of money
medium of exchange: item that buyers give to sellers when they purchase goods and services unit of account: yardstick people use to post prices and record debts store of value: item that people can use to transfer purchasing power from the present to the future

50
Commodity money
money takes form of a commodity with intrinsic vale intrinsic value: item would hav value even if it were not used as money
51
Fiat money
money without intrinsic value fiat: order of decree, and fiat money is established as money by government decree
52
Money stock
quantity of money circulating in the economy currency: paper bills and coins in public hands demand deposits: balances in bank accounts that depositors can access on demand simply by writing a check or swiping a debit card
52
Federal reserve
central bank designed to oversee the banking system and regulate the quantity of money key determinants of inflation in the long run and employment and production in the short run
53
Dual mandate of the fed
stable prices and maximum sustainable employment
54
Lender of last resort
lender to those who cannot borrow anywhere else - to maintain stability in the overall banking system
55
Money supply and monetary policy
supply: fed controls the quantity of money available in the economy, closely connected to the level of interest rates policy: setting of the money supply by policymakers in the central bank
56
Open-market operation
purchase and sale of US government bonds
57
Reserves
deposits that banks have received but have not loaned out if banks hold all deposits in reserve, banks do not influence the supply of money
58
Fractional-reserve banking
banking system in which banks hold only a fraction of deposits as reserves
59
Reserve ratio
fraction of deposits that banks hold as reserves determined by a combo of government regulation and bank policy when banks hold only a fraction of deposits in reserve, banking system creates money
60
Reserve requirement
fraction of total deposits that a bank holds as reserves
61
Excess reserves
hold reservers above the legal minimum
62
Money multiplier
amount of money that results from each dollar of reserves reciprocal of the reserve ratio higher the reserve ratio, the less of each deposit banks loan out, and the smaller the money multiplier
63

66
How the fed influences the quantity of reserves
open-market operations: buys or sells government bonds fed lending to banks: banks borrow from the fed when they do not have enough reserves on hand either to satisfy bank regulators etc.
67
Discount rate
interest rate on the loans that the fed makes to banks higher discount rate discourages banks from borrowing from the fed, decreasing the quantity of reserves in the banking system and, in turn, the money supply
68
How the fed influences the reserve ratio
reserve requirements: regulations on the minimum amount of reserves that banks must hold against deposits interest on reserves: the interest rate paid to banks on the reserves held in deposit at the fed
69
Problems in controlling the money supply
fed does not control the amount of money that households choose to hold as deposits in banks monetary controls is that the fed doesn't not control the amount that bankers choose to lend
70
Federal funds rate
short-term interest rate that banks charge one another for leans
71
Inflation
increase in the overall level of prices measured through percentage change in CPI hyperinflation: extraordinary high rate of inflation
72
Deflation
where prices fall
73
What happens are price level rises
value of money falls determined by supply and demand
74
Long-run: money supply and money demand
brought into equilibrium by the overall level of prices
75
Quantity theory of money
quantity of money available in an economy determines the value of money, and growth in the quantity of money is the primary cause of inflation
76
Effects of monetary injection
create an excess supply of money increases demand for goods and services
77
Nominal variables
variables measured in monetary units
78
Real variables
variables measured in physical units
79
Monetary neutrality
the proposition that changes in the money supply do not affect real variables and affects nominal variables
80
Velocity of money
rate at which money changes hands V = (P x Y) / M P: price level Y: quantity of output (real GDP) M: quantity of money
81
Quantity equation
M x V = P x Y
82
Five points on the quantity theory of money
-The velocity of money is relatively stable over time. -Because velocity is stable, when the central bank changes the quantity of money (M), it causes proportionate changes in the nominal value of output (P × Y). -The economy’s output of goods and services (Y) is determined by factor supplies (labor, physical capital, human capital, and natural resources) and the available production technology. In particular, since money is neutral, money does not affect output. -Because output (Y) is fixed by factor supplies and technology, when the central bank alters the money supply (M) and induces a proportional change in the nominal value of output (P × Y), this change is reflected in a change in the price level (P). -Therefore, when the central bank increases the money supply rapidly, the result is a high rate of inflation.
83
Inflation tax
the revenue the government raises by creating money inflation tax is like a tax on everyone who holds money
84
Real interest rate equation
real interest rate = nominal interest rate - inflation rate
85
Effect of increase of rate of money growth
long-run result: equal increase in the inflation rate and the nominal interest rate fisher effect: one-for-one adjustment of the nominal interest rate to the inflation rate
86
Shoeleather cost
resources wasted when inflation encourages people to reduce their money holdings
87
Menu costs
costs of changing prices
88
Expected real interest rate equation
nominal interest rate - expected inflation rate
89
Actual real interest rate equation
actual real interest rate = nominal interest rate - actual inflation rate
90
Fisher effect equation
nominal interest rate = real interest rate + expected inflation rate
91
Nominal interest rate equation
nominal interest rate = real interest rate + expected inflation rate
92
After-tax nominal interest rate equation
after-tax nominal interest rate = nominal interest rate x (1- tax rate)
93
After-tax real interest rate equation
after-tax real interest rate = after-tax nominal interest rate - inflation rate
94
Price level equation
P = (M x V) / Y
95
M1 vs M2
M1: currency + demand deposits, savings deposits, traveler's check, and other checkable deposits M2: M1 + retail money market mutual fund balances, money market deposit accounts, and small denomination time deposits
