Gross Domestic Product
(GDP)
Definition: The market
value of all final
goods and services
produced in a
country in a year
– Current/nominal GDP
(measured for the given year,
reflects inflation )
– Real GDP
(set on a constant base year)
Gross Domestic Product
(GDP)
GDP is measured by
totaling money
spent on four
categories:
– Consumption (C)
– Investment (I)
– Government Spending
(G)
– Net Exports
• Exports (X) - imports (M)
– GDP= C+I+G+ (X-M)
Consumer and Government
Spending
• Consumer: The spending by
households on goods and
services.
– A new car, food, clothes,
college tuition, sporting
event, health insurance.
– Makes up 66% of GDP
• Government: Spending by
all levels of government on
goods and services

Investment

Spending by
capital
– machinery, factories,
equipment, tools,
computers, new
buildings, inventory
– 12-14% of total GDP
Net Exports
• Definition: Spending by
people outside the United
States on US produced
goods and services (exports,
or X) minus spending by
people in the United States
on foreign goods and service
(imports, or M)
– (X-M) = Net Exports
– (X) Jonas Brothers sell CDs
in Japan
– (M) You buy a camera made

Gross Domestic Product
How to Calculate
• GDP is calculated by multiplying
the quantity of each final good
and service produced (Q) in a
year by their estimated price (P)
to get the dollar value (DV), and
then adding all dollar values of
each to get the total GDP.
• GDP = C + G +I + (X-M)
Consumer Spending Q x P = DV
+
Investment
Q x P = DV
+
Govt. Spend
Q x P = DV
+
Net Exports
(X- M)
Gross Domestic Product
How to Calculate
Calculation Example
# in the millions
Cons. Goods 6m cars x \$20,000= \$120,000m
Cons. Service 150m haircuts x \$15= \$2,250m
Bus. Invest. 2m buildings x \$300,000= \$600,000m
Govt. Spend. 1m roads x \$5,000= \$5,000m
Net Exports 40m apples (export) x \$1= \$40m(X)
50m apples (import) x \$1= \$50m (M)
GDP=
\$120,000m cars
\$ 2,250m haircuts
\$600,000m buildings
\$727,350m
10m net loss in apple exports
\$727,250m

transactions
– Increase in leisure and

work
Genuine Progress Indicator (GPI)
Subtracts for
• Crime = \$40 billion/yr
• Pollution and loss of natural
resources
– Counts \$1.2 billion in toxic
clean-up costs decrease
• Health care expenditures for
preventable illness
– Heart attacks
– High blood pressure
• Loss in infrastructure
– From natural disasters or war
• Foreign debt counts as
negative
– GDP can count as positive
government spending
