7.1 Explain how total production is measured.
7.2 Discuss whether GDP is a good measure of well-being.
7.3 Discuss the difference between real GDP and nominal GDP.
7.4 Become familiar with other
measures of total production
and total income.

Gross Domestic Product Measures Total Production
Learning Objective 7.1
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.

Measuring GDP by the Value-Added Method
Value added The market value a firm adds to a product.
Table 7-1
Calculating Value Added
FIRM VALUE OF PRODUCT VALUE ADDED
Cotton Farmer Value of raw cotton = $ Value added by cotton farmer = 1
Textile Mill Value of raw cotton woven into cotton fabric = $3
Value added by cotton textile mill = ($3 – $1) = 2
Shirt Company Value of cotton fabric made into a shirt = $15
Value added by shirt manufacturer = ($15 –$3) = 12
L.L. Bean Value of shirt for sale on L.L. Bean’s Web site = $35
Value added by L.L. Bean = ($35 – $15) = 20
Total Value Added = $35

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.)
