Chapter 7: GDP: Measuring Total Production and Income Gross Domestic Product Measures Total Production Production, Income, and the Circular-Flow Diagram FIGURE 7-1 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. 7.1 LEARNING OBJECTIVE Explain how total production is measured.

Chapter 7: GDP: Measuring Total Production and Income Gross Domestic Product Measures Total Production Production, Income, and the Circular-Flow Diagram FIGURE 7-1 (continued) 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.

National income is calculated as GDP minus the consumption of fixed capital, or depreciation. Disposable personal income is equal to personal income minus personal tax payments. Personal income is income received by households.
