1
Q
absolute advantage
A
a situation in which a person or country can produce more of a particular product from a specific quantity of resources than some other person or country
2
Q
capital
A
human-made resources (buildings, machinery, and equipment) used to produce goods and services; goods that do not directly satisfy human wants; also called capital goods
3
Q
ceteris paribus
A
The assumption that factors other than those being considered are held constant
4
Q
comparative advantage
A
a situation in which a person or country can produce a specific product at a lower opportunity cost than some other person or country; the basis for specialization and trade
5

9
Q
inferior goods
A
A good or service whose consumption declines as income rises, prices held constant
10
Q
law of demand
A
The principle that, other things equal, an increase in a product’s price will reduce the quantity of it demanded, and conversely for a decrease in price
11
Q
law of supply
A
The principle that, other things equal, an increase in the price of a product will increase the quantity of it supplied, and conversely for a price decrease
12
Q
macroeconomics
A
The part of economics concerned with the economy as a whole; with such major aggregates as the household, business, and government sectors, and with measures of the total economy
13
Q

23
Q
final goods
A

31

32
rule of 70
the number of year it will take for some measure to double, i.e for price level doubling, divide 70 by annual inflation rate
33
demand-pull inflation
inflation caused by there being more demand than there is output at the existing price levels
34

43
financial account
Part of the balance of payments which consists of purchases and sales of international assets such as stocks, bonds, factories, buildings, and currency by a central bank
44
Expenditure Approach for calculating GDP
Adds together Consumption + Investment + Government Spending + Exports - Imports (C+I+G+X-M)
45
Income Approach for calculating GDP
Add together Wages + Profits + Interest + Rent (W+P+I+R)
46
GDP Deflator (Price Index)
a measure of the price level, calculated by dividing nominal GDP by real GDP and multiplying by 100
47
Non-discretionary Fiscal Policy
Automatic Stabilizers (permanent laws, wellfare, unemployment, income tax)
48
Discretionary Fiscal Policy
Congress creates a bill that is designed to change AD through gov spending or taxation (lag time is an issue)
49
Stagflation
Slow growth, high unemployment rate, high inflation (SRAS shifts left)
50
Crowding Out
The decrease in private expenditures that occurs as a consequence of increased government spending or the financing needs of a budget deficit
51
Discretionary Demand-Side Fiscal Policy
Deliberate changes of government expenditures and/or taxes to achieve particular economic goals
52
Expansionary Demand-Side Fiscal Policy
Increases in government expenditures and/or decreases in taxes to achieve particular economic goals
53
Fiscal Policy
Changes in government expenditures and/or taxes to achieve economic efficiency
54
Interest Rate Effect
The changes in household and business buying as the interest rate changes
55
International Trade Effect (Net Export Effect)
The change in foreign sector spending as the price level changes.
56
Marginal Propensity to Consume (MPC)
The fraction of any change in income spent on domestically produced goods and services; equal to the change in consumption divided by the change in disposable income.
57
Marginal Propensity to Save (MPS)
The fraction of any change in income that is saved; equal to the change in savings divided by the change in disposable income.
58
MPC + MPS = 1
The fraction of an increase in disposable income that is spent (MPC) plus the fraction that is saved (MPS) must equal 1.
59
Multiplier Effect
The increase in total spending in an economy resulting from an initial injection of new spending. The size of the multiplier effect depends upon the spending multiplier. An effect in economics in which an increase in spending produces an increase in national income and consumption greater than the initial amount spent.
60
Spending multiplier
= 1/(1-MPC) or 1/MPS. This tells you how much total spending an initial interjection of spending in the economy will generate. For example, if the MPC = .8 and the government spends $100 million, then the total increase in spending in the economy = $100 x 5 = $500 million.
61
Sticky wage and price model
The short-run Aggregate-Supply Curve is sometimes referred to as the "sticky wage and price model," because workers' wage demands take time to adjust to changes in the overall price level, and therefore, in the short-run an economy may produce well below or beyond its full employment level of output.
62
Real Balances Effect = Wealth Effect
One of the reasons the aggregate demand curve slopes downward: The tendency for increases in price level to lower the real value (or purchasing power) of financial assets with fixed money value and, as a result, to reduce total spending and real output. The idea that any wealth that you may have in the form of a cushion or securities becomes less valuable as prices rises because higher prices reduce real spending power, prices and output are negatively related.
63
2 Tools of Fiscal Policy
Federal Government engages in fiscal policy. Tool # 1 = Government Spending. Tool # 2 = Personal Income Taxes.
64
Classical Economic Theory
The view that an economy will self-correct from periods of economic shock if left alone. Also known as "laissez-faire" and derived from the thinking of Adam Smith, Thomas Malthus, and David Ricardo. Neoclassical theories are up-to-date versions of similar belief systems. Key idea that price levels and wages are fully flexible both upwards and downwards.
65
Transfer Payment
A payment made when no good or service is exchanged. Allowances are private transfer payments; social security checks are governmental transfer payments. Transfer payments are NOT included in GDP because they do NOT represent production.
66
factors of production
resources; includes land, labor, capital, and entrepreneurship.
67
marginal utility
extra usefulness a person gets from consuming one more unit of a product.
68
diminishing marginal utility

69
movement along the demand curve
change in quantity demanded, caused only by a change in price
70
price ceiling

96
Money Supply Curve
shows the relationship between the quantity of money supplied and the interest rate. This curve is vertical and can only shift because of monetary policy
97
Money Demand Curve
a graphical representation of the negative relationship between the quantity of money demanded and the interest rate; the money demand curve slopes down because, other things equal, a higher interest rate increases the opportunity cost of holding money
98

104
supply for loanable funds
Direct relationship between real interest rate and loanable funds supplied. People will invest more at higher interest rates. The amount of savings made available to be loaned out
105
National Savings (Closed Economy)
Total amount of private and public savings. Closed economy means there is no trade occurring.
106
National Savings (Open Economy)

115
why does monetary policy work?
bc the money multiplier!
116
velocity of money
measures the number of times that the average dollar bill is spent in a year, the ratio of nominal GDP to the money supply
117
what do the letters stand for in M x V = P x Y
m = money supply, v = velocity of money, p = price, y = real gdp
118
money neutrality
changes in the money supply have no real effects in the economy
(in the LR, the only effect of the increase in the money supply is an increase in APL)
119
assumption about fixed income
people on fixed incomes will lose if there is high inflation (because APL goes up and their income does not change with it)
120
assumption about banks making fixed loans
banks who make loans on fixed interest rates will lose if there is high inflation
121
assumption about inflation rates and saving
when inflation rates are high, people will hold less money
122

123
seigniorage
the government's right to print money
124

133
long-run phillips curve
shows the relationship between unemployment and inflation after expectations of inflation have had time to adjust to experience
134
debt deflation
the reduction in aggregate demand arising from the increase in the real burden of outstanding debt caused by deflation
135
Keynesian theory
-emphasized the short-run effects instead of long-run
-SRAS is upward sloping, not vertical
