-
Real GDP
- short for real gross domestic product
- total value of all final goods and services produced during a particular year or period that is adj to eliminate effects of changes in prices
-
business cycle
- series of expansions and contractions of the real GDP
- begins at peak continues thru a recession, a trough and expansion new cycle begins at next peak
-
peak
point of business cycle at which expansion ends & a recession begins
-
recession
sustained period in which the real GDP is falling from the peak to trough
-
trough
- point at which recession begins and expansion begins
- real GDP starts to rise
-
expansion
- from trough to peak
- a rise in real GDP until it peaks at which time the new cycle begins
-
price indexes
- current cost of basket divided by base period cost of basket
- base period always has a price index of 1
-
4 steps in computing price index
- 1. select kinds & quantities of goods & services to be included (a market basket)
- 2. determine what it would cost to buy them in some period (base period) for comparision often 1 year
- 3. compute cost of market basket in current period
- 4. compute price index (current cost/base period cost)
-
Price index formula
current cost of basket / base period cost of basket
published often multiplied by 100
-
base period
time period against which costs of market basket in other periods will be compared in computing price index is always at 1
-
Consumer Price Index (CPI)
- price index reflects changes in prices of goods & services typically purchased by consumers
- change in cost of living (same as PI)
-
producer price index (PPI)
measure of average prices received by producers for raw materials, intermediate & final goods
-
Implicit price deflator
- price index for all final goods & services produced
- ratio of nominal GDP to Real GDP
- most board based price index available
-
Computing rate of inflation/deflation
- % rate of change in price index between 2 periods
- (price index for current period - price index for base period)/price index for base period
-
real value of money
- value expressed in units of constant purchaing power always at the base period
- nomial value $/price index of base period
-
nominal value
value expressed in dollars of the current period
-
labor force
- defined as all residents over the age of 16 who are not institutionalized and looking for work or working
- employed + unemployed but looking for work
-
unemployement rate
- unemployed but looking for work/labor force
- % of labor force unemployed
-
Frictional unemployement
short term, usually because workers and employers have to find one another
-
structural unemployment
- reflects imperfect match up of employee skills & skill requirements of available jobs or permanent reduction in demand for industry's output
- can be cuased by advancements in technology
-
cyclical unemployement
product of business cycle flucutations increases during recession and decreases during growth of economy
-
seasonal unemployment
product of regular, recurring changes in hiring needs of certain industries on monthly or seasonal basis (retail sales during non holiday season)
-
discouraged worker
workers who have looked for work in the past year but stopped because they believe they will not be hired
-
underemployement
employement of workers in jobs that do not utilize productive skills
-
natural level of employment
employment level at which quantity of labor demanded equals quantity supplied
-
natural rate of unemployment
excluded cyclical unemployment
-
Gross Domestic Product (GDP)
- market value of final goods and services produced within a country during a specific time period, usually a year
- (only final goods and services count, excludes financial transaction & income transfers, within the geographic boundaries and net additions to inventory are current period output so included)
-
value added
sum of the intermediate goods used to produce the final output
-
GDP as Expenditures
- sum of amount each sector spends on final user goods & services
- personal consumption expenditures (C)
- gross private domestic investment (I) not stock
- goverment purchases of goods & services (G)
- net exports (X) (exports - imports)
- GDP = C+I+G+X
-
GDP as Income
- adding up the income of all sectors
- wages (including benefits)
- interest (net interest paid by business plus net interest received from foreigners)
- rent (earned from seeling use of real estate
- profits (sum of corporate profits plus proprietors income)
- Capital Consumption Allowance (depreciation of capital goods plus value of accidental damage to capital goods)
- indirect business taxes (taxes collected by business & turned over to governments)
- Statistical discrepeancy (miscellaneous money allowing GDP to equate with GDI (Gross Domestic Income)
-
Gross National Product (GNP)
- total value of final goods & services produced during a given period by citizens of country no matter where they live (goods & services are produced by the "nationals" of the country)
- GDP + foreign nationals production
-
Net National Product (NNP)
- GNP net of depreciation, includes net investment instead of gross investment
- (gross investment minus CCA (capital consumption allowance - depreciation))
-
National Income (NI)
- NNP less statistical discrepancy
- measure of income payments that actually go to resources
-
Personal Income (PI)
national income plus income currently received but not earned minus income currently earned but not received
-
Disposable Personal Income
personal income (PI) minus personal taxes
-
Nominal GDP
measure of national output based on current prices of goods & services
-
Real GDP
measure of quantity of final goods & services produced, obtained by eliminating the influence of price changes from nomial GDP statistics
-
consumption
flow variable measuring value of goods & services purchased by households during time period
-
private investment
value of all goods produced for use in production of other goods & services; expenditures by buesiness on assets, on new residential houseing & changing in business inventories
-
government purchases
purchases of goods & services plus output produced by government agencies (does not include SS, welfare & unemployment compensation (transfer payments))
-
net exports
total sales of goods & services to buyers elsewhere in the world minus imports from foreign countries
-
Net Domestic Product (NDP)
GDP minus depreciation
-
nominal vs real GDP
real does not record items produced but not exchanged like a periosn preparing own dinner, or bartering & unreported income
-
investment spending
spending by firms to buy capital or produce inventory or on new residential housing
-
aggregate demand
relationship between real GDP & price level (implicit price deflator)
-
aggregate demand curve
- graphical representation of aggregate demand
- shows relationship between total quantity of output demanded (measured as real GDP) & price level (implicit price deflator) with neg relationship between price level & total quantity of goods/services demanded suggesting ordinary demand curve
-
multiplier
change in real GDP demanded at each level divided by initial change (in components of AD)
-
change (real GDP demanded at each price level)
multiplier times inital change
-
Aggregate supply (AS)
total supply of goods & services at given price level
-
long term run of AS
vertical line where AD & AS meet at a certain price level (is potential output)
-
factors changing AS
quantity of goods & services supplied, decrease/increase in price of natural resources
-
factors changing AD
any of the factors in GDP
-
wealth effect
tendency for change in price level to affect real wealth and thus alter consumption
-
interest rate effect
tendency for change in price level to affect interest rate & thus affect quantity of investment demanded
-
potential output
level of output an economy can acheive when labor is employed at its natural level
-
inflationary growth
increase in AD
-
contraction
decrease in AD
-
deflationary growth
increase in AS
-
stagflation
decrease in AS
-
sticky price
price that is slow to adjust to equilibrium level creating sustained periods of shortange or surplus
-
implicit price inflator
same as price index (nominal GDP)/(real GDP) all times 100
