Explanations of GDP and its
Components
It is common to see the following equation in
economics textbooks:
GDP = C
+ I + G + NX
Consumption spending (C)
consists of consumer spending on goods and services. It is often divided into
spending on durable goods, non-durable goods, and services. These purchases
accounted for 70 percent of GDP in the first quarter.
- Durable goods are items
such as cars, furniture, and appliances, which are used for several years
(9%).
- Non-durable goods are
items such as food, clothing, and disposable products, which are used for only
a short time period (21%).
- Services include rent
paid on apartments (or estimated values for owner-occupied housing), airplane
tickets, legal and medical advice or treatment, electricity and other
utilities. Services are the fastest growing part of consumption spending
(41%).
Investment spending (I)
consists of non-residential fixed investment, residential investment, and
inventory changes. Investment spending accounts for 15 percent of GDP, but
varies significantly from year to year.
- Non-residential fixed
investment is the creation of tools and equipment to use in the production of
other goods and services. Examples are the building of factories, the
production of new machines, and the manufacturing of computers for business
use (10%).
- Residential investment is
the building of a new homes or apartments (5%).
- Inventory changes consist
of changes in the level of stocks of goods necessary for production and
finished goods ready to be sold (0%).
Government spending (G) consists of federal,
state, and local government spending on goods and services such as research,
roads, defense, schools, and police and fire departments. This spending (19%)
does not include transfer payments such as Social Security, unemployment
compensation, and welfare payments, which do not represent production of goods
and services. Federal defense spending now accounts for approximately 5 percent
of GDP. State and local spending on goods and services
accounts for 12 percent of GDP.
Net Exports (NX) is equal to exports
minus imports. Exports are items produced in the
U.S. and
purchased by foreigners (10%). Imports are items produced by foreigners and
purchased by
U.S. consumers
(14%). Thus, net exports (exports minus imports) are negative, about - 4% of the
GDP.
