ECON CH 6 Flashcards
GDP measures (3)
- total production (Y) of G&S in the economy
- aggregate income (Y) of everyone in the economy
- aggregate expenditure (AE) on G&S produced in the economy
GDP measures (3)
- total production (Y) of G&S in the economy
- aggregate income (Y) of everyone in the economy
- aggregate expenditure (AE) on G&S produced in the economy
why does income(Y)=expenditure (AE)
because every dollar of expenditure by a buyer is a dollar in revenue for the seller
GDP is a method used to measure (2)
- national output
2. national income
GDP definition
is the aggregated market value of all final goods and services produced by all factors of production located within a country in the current year (or quarter)
GDP only includes what
the final good of the production
EX: steel is not included in GDP b/c its included in the car (as the final good)
final goods and services refers to
goods and services produced for final use (or consumption) only
EX: tires you buy to replace a flat tire
intermediate goods are
goods produced by one firm for use in further processing by another firm
EX: tires mounted on the wheels of a new car before the car is sold
GDP does not include what (2)
- used goods
EX: used car - paper transactions
EX: buying shares of stock
GDP measures the
output produced by factors of production located within the domestic economy
GNP
measures the output of all U.S. owned factors of production, regardless of where the output is produced
EX: chevy produced in factory in mexico would be counted in the US GNP b/c is owned by a US company
GDP=
Y=AE=C+I+G+(EXP-IMP)
C=70%
I=17%
G=20%
NX= -5%
the expenditure approach
a method of computing GDP that measures the total amount spent (AE) on domestically produced goods and services during a given period
the expenditure approach
a method of computing GDP that measures the total amount spent (AE) on domestically produced goods and services
the expenditure approach (GDP=AE) which is the sum of what 4 components
- personal consumption expenditures ( C )
- durable goods, nondurable goods, services - gross private domestic investment (I)
- nonresidential investment, residential investment, change in inventories - government expenditures (G)
- federal, state, and local - net exports (NX=EX-IM)
- exports and imports
the expenditure approach (GDP=AE) which is the sum of what 4 components
- personal consumption expenditures ( C )
- durable goods, nondurable goods, services - gross private domestic investment (I)
- nonresidential investment, residential investment, change in inventories - government expenditures (G)
- federal, state, and local - net exports (NX=EX-IM)
- exports and imports
unsold output goes into
inventory investment, whether it was intentional or not
change in inventories=
GDP-total sales
debbie spends $200 to buy her husband dinner at the finest restaurant in Boston
Consumption ( C ) and GDP will rise by $200
Sabrina spends $1800 on a new laptop in her publishing business. the laptop was build in china
investment (I) rises by 1800, net exports fall by 1800, and GDP is unchanged
Jane spends $1200 on a computer to use in her editing business. she got last years model on sale for a great price from a local manufacture
current GDP and investment do not change, b/c the computer was built last year

why do we care about GDP (2)
- most important macro variable (statistic)
- best recipe for happiness macro has to offer
- large GDP enables people to enjoy better schools, cleaner environment, better health care, and longer life
- many indicators of the quality of life are positively correlated with GDP

current GDP and investment do not change, b/c the computer was built last year
general motors builds $500 mill worth of cars, but consumers only buy $470 mill of them
consumption rises by 470 mill, inventory investment rises by 30 mill, and GDP rises by 500 mill
base year
the year chosen for the weights in a fixed-weight procedure
nominal GDP
values output using current year prices (current dollars or nominal dollars)
- not corrected for inflation
- year=(PxQ)+(PxQ)
real GDP
values output using the prices of the base year
- is corrected for inflation
- base year= (base PxQ)+(base PxQ)
base year (fixed weight) procedure
use the prices of the same year (base year) as weights when determining the value of real GDP
-a weight is the importance attached to an item within a group of items
chain weight procedure
uses prices (weights) of two adjacent years
%change NGDP
NGDP big/little= NGDP big- NGDP little
divided by NGDP little x100
economics are concerned with how the overall price level ℗ changes b/c
they want to keep inflation under control
calculate inflation
%changeP big/little= P big- P little divided by P little x100
overall price level ℗ is calculated by using two methods
- the GDP deflator
2. the consumer price index
the GDP deflator in a year
Pyear= GDP delf year= NGDP year/RGDP year x100
GDP / Capita = (3)
- economic well being
- national welfare
- standard of living
GDP does not include (6)
- the quality of the environment
- leisure time
- non-market activity
- an equitable distribution of income
- underground economy (shadow economy)
- many, many other “thinks” that make our lives worth living
why do we care about GDP (2)
- most important macro variable (statistic)
- best recipe for happiness macro has to offer
- large GDP enables people to enjoy better schools, cleaner environment, better health care, and longer life
- many indicators of the quality of life are positively correlated with GDP
nonresidential investment
expenditures by firms for machines, tools, plants, and so on
residential investment
expenditures by households and firms on new houses and apartment buildings
change in business inventories
the amount by which firms` inventories change during a period. inventories are the goods that firms produce now but intend to sell later
-(production-sales)
depreciation
the amount by which an assets value falls in a given period
net investment
gross investment minus depreciation
gross investment
the total value of all newly produced capital goods produced in a given period
national income
the total income earned by the factors of production owned by a country`s citizen
dispositional personal income or after-tax income
personal income minus personal income taxes. the amount that households have to spend or save
current dollars
the current prices we pay for goods and services
-negatively related with the central producer
base year
the year chosen for the weights in a fixed-weight procedure
5 steps to calculate CPI and inflation rate
- Q in the basket
- P for GS in the basket
- calculate COD
- CPI year= COB year/ COB base x100
- inflation rate= %change overall price level
