AP Macroeconomics (copy)
UNIT 1: Basic Economic Concepts
Scarcity: unlimited wants with limited resources
Macroeconomics: study of the economy as a whole
Microeconomics: study of small economic units
4 factors of production: land, labor, capital, entrepreneurship
opportunity cost: the loss of potential gain when choosing to produce one thing over another
households provide in the product market: money
households demand in the product market: goods
firms provide in the product market: goods
firms demand in the product market: money
households demand in the factor market: wages
households supply in the factor market: labor
firms demand in the factor market: labor
firms supply in the factor market: wages
Absolute advantage: can produce the most output or requires the least input
comparative advantage: lowest opportunity cost
UNIT 2: Economic Indicators
GDP: the total dollar value of all final goods and services produced within a country's borders in a given year
formula to calculate GDP: C+I+G+Xn
3 things not counted in GDP: intermediate goods, non production transactions, nonmarket/illegal activities
intermediate goods: goods inside the final goods
non production transactions: nothing produced or used goods, transfer payments
non market and illegal activities: things made at home
transfer payment: welfare, social security, subsidies
GNP: the value of all finished goods and services owned by a countries citizens
GDP per capita: GDP/population, used to calculate standard of living
frictional unemployment: in-between jobs or looking for first job
structural unemployment: skillset isn’t needed anymore
cyclical unemployment: caused by a recession or economic downturn
formula for calculating unemployment rate: unemployed/labor force x 100
who is in the labor force: at least 16, willing and able to work
discouraged worker: no longer looking for work
natural rate of unemployment: frictional+structural unemployment
expenditure approach for calculating GDP: C+I+G+(x-m)
income approach: wages+interest+rent+profit
expenditure approach=income approach because: one person’s spending is always equal to another’s income
who is helped by inflation: borrowers
hurt by inflation: lenders, ppl with fixed income, savers
CPI: (price of market basket/price of basket in particular year)x100
inflation rate: (new-old)/old x 100
real GDP: (nominal/deflator) x100
real interest rate nominal-inflation rate
nominal interest rate: real + inflation rate
UNIT 3: National Income and Price Determination
why is the AD downward sloping: wealth effect, interest rate effect, foreign trade effect
wealth effect: higher price levels reduce the purchasing power of money, which decreases the quantity of expenditures
interest rate effect: when the price level increases lenders need to charge higher interest rates to get a real return on their loans
Foreign trade effect: when us price level increases, foreign buyers purchase less us goods and Americans buy more foreign goods
wages and resource costs in the short run: fixed
wages and resources in the long run: flexible
shifters of the aggregate demand curve: consumption spending, investment spending, government expenditures, net exports
shifters of SRAS: resource costs, actions by the government, productivity
shifters of LRAS and PPC: change in resource quantity or quality, change in technology
cost push inflation: higher production costs increase prices
demand pull inflation: demand increases AD which increases price levels
stagflation: high employment, low GDP, high price levels
expansionary fiscal policy: increase gov spending, decrease income taxes, creates budget deficit
contractionary fiscal policy: decrease gov spending, increase income taxes, creates budget surplus
spending multiplier: 1/MPS
tax multiplier: one less than spending multiplier
does the spending or tax multiplier have a larger impact on RGDP: spending
discretionary fiscal policy: Congress creates a new bill to change AD through gov spending or taxation
Non discretionary fiscal policy: automatic stabilizers
UNIT 4: Financial Sector
common assets: reserves, government bonds/securities, loans
common liabilities: demand deposits
formula for money multiplier: 1/reserve requirement
government bonds/securities: IOUs, represent the debt that must be repaid to the lender
discount rate: interest charged by the fed for overnight loans
federal funds rate: interest charged by commercial banks for overnight loans
expansionary monetary policy for limited reserves: buy bonds, decrease discount rate, decrease reserve requirement
contractionary monetary policy for limited reserves: sell bonds, increase discount rate, increase reserve requirement
administered rates: interest on reserves (IOR) and discount rate
expansionary monetary policy: decrease administered rates
contractionary monetary policy: increase administered rates
3 functions of money: medium of exchange, unit of account, store of value
medium of exchange: used to buy goods and services
unit of account: measures the value of goods and services
store of value: store purchasing power for the future
crowding out: deficit spending raises interest rates which decreases the amount of investment spending.
UNIT 5: Long-Run Consequences of Stabilization Policies
equation of exchange: MxV=PxQ
M: money supply
V: velocity
P: price
Y: RGDP, quantity of output
why is SRPC downward sloping: there is a tradeoff between unemployment and inflation
why is LRPC vertical: there is no tradeoff between unemployment and inflation
what causes the LRPC to shift: change in the NRU, change in unemployment compensation
UNIT 6: Open Economy International Trade and Finance
net exports: exports-imports
current account: a country's net income over a period of time
what’s in a country’s current account: goods and services, investment income, net transfers
capital/financial account: net change of assets and liabilities during a particular year
current and capital account must ________ : equal each other
appreciation: the increase of value of a country’s currency with respect to a foreign currency
Depreciation: loss of value of a country’s with respect to a foreign currency
4 shifters of the FOREX: changes in, taste, relative income, price levels, and relative interest rates
