Gross Domestic Product
Measures Total Production
7.1 LEARNING OBJECTIVE
Explain how total production is
measured.
Chapter 7: GDP: Measuring Total Production and Income
Measuring Total Production: Gross Domestic Product
Gross domestic product (GDP)
The market value of all final goods
and services produced in a country
during a period of time, typically one
year.
GDP Is Measured Using Market Values, Not Quantities
The word value is important in the
definition of GDP.

Gross Domestic Product
Measures Total Production
7.1 LEARNING OBJECTIVE
Explain how total production is
measured.
Production, Income, and the Circular-Flow Diagram
FIGURE 7-1
Chapter 7: GDP: Measuring Total Production and Income
The Circular Flow and the
Measurement of GDP
The circular-flow diagram illustrates
the flow of spending and money in the
economy.
Firms sell goods and services to three
groups: domestic households, foreign
firms and households, and the
government.
To produce goods and services, firms
use factors of production: labor,
capital, natural resources, and
entrepreneurship. Households supply
the factors of production to firms in
exchange for income in the form of
wages, interest, profit, and rent.
Firms make payments of wages and
interest to households in exchange for
hiring workers and other factors of
production.
The sum of wages, interest, rent, and
profit is total income in the economy.
We can measure GDP as the total
income received by households.

Production, Income, and the Circular-Flow Diagram
FIGURE 7-1 (continued)
Chapter 7: GDP: Measuring Total Production and Income
The Circular Flow and the
Measurement of GDP
The diagram also shows that
households use their income to
purchase goods and services, pay
taxes, and save. Firms and the
government borrow the funds that
flow from households into the
financial system.
We can measure GDP either by
calculating the total value of
expenditures on final goods and
services or by calculating the value
of total income.

Consumption accounts for 70 percent of GDP, far more than any of the other components. In recent years,
net exports typically have been negative, which reduces GDP.

7.1 LEARNING OBJECTIVE
Explain how total production is
measured.
An Equation for GDP and Some Actual Values
• Consumer spending on services is greater than the sum
of spending on durable and nondurable goods.
Chapter 7: GDP: Measuring Total Production and Income
• 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.

Discuss the difference between

Comparing Real GDP and Nominal GDP
FIGURE 7-3
Chapter 7: GDP: Measuring Total Production and Income
Nominal GDP and
Real GDP, 1990–2008
Currently, the base year for
calculating GDP is 2005. In
the years before 2005,
prices were, on average,
lower than in 2005, so
nominal GDP was lower
than real GDP. In 2005,
nominal and real GDP were
equal. After 2005, prices
have been, on average,
higher than in 2005, so
nominal GDP is higher than
real GDP.

Other Measures of Total
Production and Total Income
7.4 LEARNING OBJECTIVE
Become familiar with other
measures of total production and
total income.
Gross National Product (GNP)
Gross national product (GNP) is the value of final goods and
services produced by residents of the United States, even if the
production takes place outside the United States.
Chapter 7: GDP: Measuring Total Production and Income
National Income
National income is calculated as GDP minus the consumption of
fixed capital, or depreciation.
Personal Income
Personal income is income received by households.
Disposable Personal Income
Disposable personal income is equal to personal income minus
personal tax payments.

Measures of Total Production
and Total Income, 2008
The most important measure of total production and total income is gross domestic product (GDP). As we will see in
later chapters, for some purposes, the other measures of total production and total income shown in the figure turn
out to be more useful than GDP.

The Division of Income
FIGURE 7-5
The Division of Income
We can measure GDP in terms of total expenditure or as the total income received by households. The
largest component of income received by households is wages, which are more than three times as large
as the profits received by sole proprietors and the profits received by corporations combined.
