Learning Objectives
19.1 Explain how total production
is measured.
19.2 Discuss whether GDP is a good
measure of well-being.
19.3 Discuss the difference between
real GDP and nominal GDP.
The business cycle does not
affect all industries in the same
way. For example, some
trucking firms experienced
slow sales during 2006 while
airlines were prospering.
19.4 Become familiar with other
measures of total production
and total income.

Gross Domestic Product Measures Total Production
Measuring Total Production: Gross Domestic Product
Gross domestic product (GDP)

and services produced in a country
during a period of time, typically one
year.

An Equation for GDP and Some Actual Values
• Consumer spending on services is greater than the sum
of spending on durable and nondurable goods.
• Business fixed investment is the largest component of
investment.
• Purchases made by state and local governments are
greater than purchases made by the federal government.
• Imports are greater than exports, so net exports are
negative.

An Inside LOOK
Trucking Industry Depends on the
Goods—Not Services—Component of GDP
Economic Slowdown Slams Breaks on Trucking Sector
As goods decline as a percentage of GDP, so does the demand for ground-freight transportation
services. (The goods and services shares of GDP do not sum to 100 percent because GDP is
composed of goods, services, and structures.)
