Why Do We Care About GDP?
• Large GDP  afford better schools,
cleaner environment, health care…
• Many indicators of the quality of life
are positively correlated with GDP.

So what is Gross Domestic
Product?
Gross Domestic Product
(GDP)
Gross Domestic Product is the market value of
all final goods and services produced within a
country in a given period of time
…the market value of all final goods &
services produced within a country
in a given period of time.
Gross Domestic Product (GDP) Is…
Market prices
 Same units, value to buyer and seller
 No market value  excluded from GDP
 i.e. housework you do for yourself.
…the market value of all final goods &
services produced within a country
in a given period of time.
Gross Domestic Product (GDP) Is…
Final goods: intended for the end user
Intermediate goods: inputs to produce other
goods
Final goods include intermediate goods

Services i.e. cell phone service, lawn mowing (if
purchased), dry-cleaning…
…the market value of all final goods &

In each of the following cases, determine if it would
be counted in Gross Domestic Product.
A. Caroline goes to the store a buys chocolate chip
cookies to eat.
B. Bob goes to the store and buys chocolate chip
cookies for his catering business to include in an
order
C. Jim mows his own lawn
D. Nancy pays someone to clean her house

Consumption (C)
is total spending by households on g&s.
• Note on housing costs:
• Renters and Homeowners both
“consume” “housing services”
Consumption (C)
• Renters:
C includes rent payments.
• Homeowners:
C includes the “imputed rental value”
of the house
Gov’t counts homeowner as both
• Landlord
• Renter
Renter Landlord
Rental Expense = Rental income
And… rental expense (imputed rent) counted in consumption
Consumption (C)
– “as if” renting their home (from themselves)
– Not the purchase price or mortgage
payments
• Purchase of home is “investment” which
produces “housing services”
• Renters:
C includes rent payments.
• Homeowners:
C includes the “imputed rental value”
of the house
Investment (I)
is total spending on goods that will be
used in the future to produce more goods
and services.
includes spending on
capital equipment (e.g., machines, tools)
structures (factories, office buildings, houses)
inventories (goods produced but not yet sold)
Note: “Investment” does not mean the
purchase of financial assets like stocks and
bonds.

If you own:

Government Purchases (G)
is all spending on the g&s purchased
by govt
at the federal, state, and local levels.
G excludes transfer payments, such as
Social Security or unemployment
insurance benefits. They are not
purchases of g&s.
Net Exports (NX)
NX = exports – imports
• Exports represent foreign spending
on the economy’s g&s.
• Imports are the portions of C, I, and
G
that are spent on g&s produced
abroad.
• Adding up all the components of
GDP gives:
Y = C + I + G + NX
Y = C + I + G + NX

In each of the following cases, determine how much GDP
and each of its components is affected (if at all).
A. Debbie spends $200 to buy her husband dinner
at the finest restaurant in Boston.
B. Sarah spends $1800 on a new laptop to use in her
publishing business. The laptop was built in China.
C. General Motors builds $500 million worth of cars,
but consumers only buy $470 million worth of them.
D. Jane spends $1200 on a computer to use in her editing
business. She got last year’s model on sale for a great
price from a local manufacturer.

Real vs. Nominal GDP
GDP over time
• Which is worth more?
 Did you value each in dollars?
 Same thing for GDP across time, value of dollar
changes, need constant dollar…
Changing Dollar Value
• 1950
=
 Today
=
Need to use a “constant” dollar to compare values across time!
PCoke = $.05
PCoke > $1.00
Real versus Nominal GDP
Nominal GDP values output using current
prices.
– Not corrected for inflation
– Changing prices obscure changes in Q produced
– Need to hold P constant to see ΔQ
Real GDP values output using the prices of
a base year (2012?).
– RGDP is corrected for inflation
– Use RGDP to measure changes in output

Not Perfect – Why Use It?
• How do you measure happiness?
– No accepted standard
• Income isn’t everything…
… but more income  can do what’s important
• Takes $ to provide:
– Healthcare
– Food
– Protect the environment
• “Money isn’t everything, but given the
choice, I’ll take rich”
